Solar Hybrid PCU PWM
Solar Hybrid PCU is called Solar Power Conditioning Unit that works on Grid power & Solar power along with the battery to store the Energy from the grid power & the solar power, gives backup power in case of a power failure, uses Solar Energy to run the load on the Grid, Solar, Battery and create a balance of power.
Su-vastika Solar Hybrid PCU PWM has a feature where the battery charging is done through Solar Energy, and once the battery is charged, it shifts the emphasis from Grid to Solar energy and saves the power bills. It comes with Inbuilt Solar Charge Controller based on PWM technology. So in layperson’s terms, Solar Hybrid PCU is a Solar System which provides power to the house and office in case of a power failure, and it saves the power bill by running the loads on the Solar power even when the grid power is available.
Solar Hybrid PCU is required in areas with a Grid, but power cuts or outages also occur. Solar Grid feed system does not have storage, so this Solar PCU provides power in case of Power failures or power cuts. These are called Stand Alone Inverters also.

Remote Monitoring
What Is ATC?
Automatic Temperature Control/ATC is a unique sensor added to Su-vastika Pure sine wave UPS. ATC allows our UPS to switch between 6-stage charging based on the outside temperature.
Why Is ATC Important?
A battery gets adversely affected because of the ambient temperature. ATC allows choosing the right charging stage whenever there is a temperature fluctuation. This is extremely important in places where temperature varies throughout the year. So, when the temperature increases, a generic battery might stop charging, but the Su-vastika UPS series with ATC will keep on charging. With this feature, on average, the battery’s lifespan is increased by up to 1 year.
Adaptive Performance Using ATC
Su-vastika UPS with ATC is designed for rough weather conditions. It has an ambient sensor placed right upon it. With advanced Automatic Temperature Compensation (ATC) built right into the microprocessor, Su-vastika UPS senses the temperature around it and then makes intelligent adjustments. For example, the temperature is high in summer or hotter regions, so the battery is charged to a lower voltage for the same power backup performance. This saves you some extra bucks while ensuring the battery doesn’t overheat, loose water, or get damaged.
Similarly, in winter or colder places, the temperature is lower, so the battery is charged to a higher boost voltage to ensure you get the required or expected amount of power backup. This makes our UPS with ATC a perfect choice for any climate; from the extremes of Northern America and Europe to the beating heat in Middle-East and South-East Asia, we are ready for a rough world.
Ability To Control Wirelessly (Optional)
Su-vastika has developed Bluetooth and WiFi app for all its Inverters/UPS/Home UPS/ Solar Hybrid PCU/ERD/ESS that helps to monitor and control UPS through Mobile app or direct PC and loaded with the patented software.
This feature offers many advantages over regular Inverters/UPS.
- Ease of installation
- Remote monitoring
- Real-time data
- Digital Warranty
- Voltage and frequency
- Shows charging percentage of the battery
Compatible With LiFePO4 Battery
One can buy a Lithium Ion Phosphate LifePO4 battery and install it with our Solar hybrid PCU without making any changes. We have changed the charging software along with the limits of Low battery and boost voltage according to the lithium battery. In our Bluetooth-based Solar Hybrid PCU, the user can select the switch on the mobile application and make the changes very easily. In the mobile application, there is a provision for seeing which battery you have selected so the user doesn’t change the settings by mistake. Otherwise, there may be a problem with the charging profile.
Isolation Transformer
Su-vastika Solar Hybrid PCU has Built-in Isolation Transformer also called galvanic isolation, implies that no direct path exists for the current to flow from the source to the load. An isolation transformer provides isolation between the electrical devices and the source powering these devices. In other words, the output power circuit is electrically and physically isolated from the input power circuit with an isolation transformer. As a result, the isolation transformer provides safety to the users and the appliances. This feature protects our Solar PCU in case of High and Low voltages and spikes and surges in the areas where the power is fluctuating or where the power is not very stable. Most areas have a weak neutral, and the High frequency based Solar PCUs can’t withstand this condition. In our Solar PCU, the ruggedness in the dusty environment, power variations, etc., can be handled because of this well-designed Isolation transformer.
Bi-directional Technology
Su-vastika’s Solar Hybrid PCU works on Revolutionary Bi-directional technology. A Bi-directional technology is a technology that allows for two-way charging due to its ability of two-way conversion—from AC to DC and from DC to AC. A Bi-directional technology uses the same PWM (Pulse Width Modulation) based MOSFET (metal–oxide–semiconductor field-effect transistor) circuit to charge and discharge the battery.
Safe Voltage Range (Brain With A Muscle)
When there is a sudden high voltage spike, home’s MCB might not be able to protect the appliances, but Su-vastika Solar Hybrid PCU will.
It will rapidly switch from the mains to the battery. In fact, Solar Hybrid PCU can take up to 2.5x its load capacity, supporting your entire load during that high voltage spike. It then intelligently reminds you to turn off the extra appliances, so that the load can be reduced.
Advanced Protection
Short circuits are very common in homes. Therefore every household is equipped with an MCB or Main fuse. However, these can be slow and inefficient at protecting your appliances from damage.
We know how much you love your appliances. Therefore, we have designed Solar Hybrid PCU to add a smart layer of protection to them. It has an inbuilt Special MCB, which trips and protects all your appliances even before the traditional MCB can respond.
Charging Selection
There are multiple types of Batteries available in the market, which have advantages and disadvantages, and accordingly, we charge them based on their characteristics.
For example, if we have to charge a Tubular Lead Acid battery, we have to take a minimum of 10 hours before we completely charge it. If we try to charge faster, these Batteries will be short-lived and need frequent water topping will be required. If we have to charge the Valve Regulated Lead Acid Batteries (VRLA), which are called sealed Maintenance Free batteries, they need to be charged in 6 to 8 hours, and if we try to charge them faster than that, their life is also reduced. In the case of Lithium Batteries, we can charge them in 2 to 4 hours, and they have a life cycle nearly 5 times that of Lead Acid Batteries. It’s very important how the charger of a UPS is designed to take care of the battery as the life of the battery will majorly dependent on the charger technology. Our Solar PCU has a charging capacity of 15 Amp, which can charge the 150 Ah battery in 10 hours. So the charger size is very important to check before buying any UPS.
The next parameter is how the charging is done. Is it flat charging, or it’s done in stages? In Lead Acid battery, charging must be fast until 80 per cent of the charge. Still, the rest, 20 per cent, needs little slow charging because the water is hot inside the battery when we are charging it, so we need to follow a pattern by which we reduce the heating when we are charging it so that water doesn’t evaporate and the more we control the heating inside the battery life of the battery is increased.
Adaptive Performance Using ATC
Su-vastika Solar Hybrid PCU is designed for rough weather conditions. It has an ambient sensor and antenna placed. With advanced Automatic Temperature Compensation (ATC) built right into the microprocessor, Su-vastika Solar Hybrid PCU senses the temperature around it and then makes intelligent adjustments.
For example, in summers or hotter regions, the temperature is high, and hence the battery is charged to a lower voltage for the same power back-up performance. This saves you some extra bucks while also making sure the battery doesn’t overheat, loose water, or get damaged. Similarly, in winters or colder places, the temperature is lower and hence the battery is charged to a higher boost voltage to make sure you get the required or expected amount of power back-up. This makes Su-vastika Solar Hybrid PCU a perfect choice for any climate, from the extremes of Northern America and Europe to the beating heat in Middle-East and South-East Asia, we are ready for a rough world.
Low Voltage Charging
In Low voltage areas, user uses a Voltage stabiliser and PCU to charge the battery properly. In our Solar Hybrid PCU, we also have the charging at low voltages, so there is no need for a stabiliser.
Automatic Bypass
What if your UPS has a technical error and is unable to switch your load back to the main supply? And imagine this happens in the middle of a summer night, and an electrician can only come the next morning. Intolerable, right?
This is common with almost every UPS or Inverter but not in Su-vastika Solar Hybrid PCU models because it has a feature of ‘Automatic bypass system’ which bypasses the Mains supply even when the UPS is faulty.
Battery Selection Switch
Every battery is built to accept a certain maximum allowed charging speed. A Tubular Lead-Acid battery needs a minimum of 10 hours, a Sealed Maintenance Free (SMF) battery requires 6-8 hours, while a Lithium-Ion battery requires 2-4 hours to get fully charged healthily.
Charging the batteries faster than these healthy limits reduces the battery’s life and increases maintenance costs and hassles. That’s why Solar Hybrid PCU is built with the Right Charger that charges batteries at optimum speed.
Battery Selection Switch is an innovative feature of Solar Hybrid PCU that enables you to select the battery type you have installed so that it can control and optimize the charging speed to keep your battery healthy. This makes Solar Hybrid PCU compatible with Tubular, SMF and Lithium LifePO4 batteries.
In our Bluetooth and WiFi based Solar PCU one can select the battery type from the setting on mobile application.
Battery Sizing Selection Switch
Su-vastika Solar Hybrid PCU has a feature to select the size of the battery through Bluetooth and Wi-fi application
Battery Reserve Feature OR Settable LCV For Battery
With prolonged usage, a battery’s life gets reduced. This is what happens to every battery after multiple charge-discharge cycles, even inverter batteries. Nerds call it battery fatigue.
Su-vastika Solar Hybrid PCU knows how to beat this problem too. When the battery is being used to power your appliances and is about to get empty (but not fully empty), Solar Hybrid PCU places a reserve. This means it doesn’t let the battery get fully or deeply discharged, hence extending the life of the battery by leaps and bounds.
This is similar to the reserve tank we have in our cars and scooters. It makes sure that even after you run out of battery power, you are still left with the reserved capacity to get done with emergency situations, by simply pressing a button.
Battery Reserve Mode setting % and battery low cut voltage:-
- At 0% the battery low cut voltage will be 10.5V
- At 3% the battery low cut voltage will be 10.8V
- At 5% the battery low cut voltage with be 11V
- At 8% the battery low cut voltage will be 11.2V
- At 10% the battery low cut voltage will be 11.4V
LCD Display Message
Overload & Short-circuit Feature
In Su-vastika Solar Hybrid PCU, We have given a special overload feature in which when the hybrid Solar PCU once get overloaded will retry eight times before it shuts down. This feature is very important for the user as when the extra load is run, which the Solar PCU cannot support, it switches off immediately and keeps warning. Then the user has to reduce the load and go to the ups and reset the front switch, which is very uncomfortable for the customer because, at times, the whole house gets into darkness, and for the user to switch off the load and reaches the ups is tough as it laying in one corner of home or office. So we have given a special feature in our ups; in case of overload, our ups give you eight times switching on and offload; in that time user can reduce the load, and there is no sudden darkness in the house/office.
Just like overload retries, our Solar PCU also has a feature of short circuit retries. With this feature, our Solar PCU will shut down automatically and start again whenever there is a short circuit. In this process, our Solar PCU will check whether the short circuit’s condition has been eliminated. If the short circuit has been eliminated, the UPS will start working normally. If the short circuit’s condition continues, our Solar PCU will retry 4 times before permanently shutting down. To make it operational again, reset the front switch of UPS.
Advantages Of Lithium Battery VS Lead Acid Batteries
Lithium Battery ESS Is Cheaper Than Traditional Inverters With Lead Acid Batteries
Having built SMF battery and Lithium inbuilt BESS, has a price difference of 50%, but the life is five times the battery life of the same capacity.
The life of the battery in the Lithium is more than 12 years for home and office backup purposes as the cycle life pf Lithium LifePO4 battery is 3000 cycles compared to a Lead Acid battery which gives a maximum of 400 cycles, that too if you do the proper maintenance by filling the battery with water topping in time. Lithium has 6 to 8 times the life cycle of a tubular battery, which will have a life of 12 years, in which period you will be changing at least four Lead acid batteries. So the cost of 5 Lead acid batteries compared to one Lithium battery is too low.
If we take the cost of a 70Ah Lithium battery compared to a 150Ah tubular battery, the price is almost 30 to 40% extra initially, but the life is a minimum of 4 times where the Lithium wins in the pricing part.
Comparison Of Inbuilt Battery ESS VS Traditional UPS/ Inverter With Lead Acid Batteries
Parameter | Inbuilt Lithium Battery ESS | Traditional Inverter With Lead Acid Battery |
---|---|---|
Efficiency | ESS runs with powerful Inbuilt Lithium Ion (LiFePO4) Battery, which has 3 Time higher efficiency than traditional batteries resulting higher back up and output | Traditional Inverters battery have lower efficiency as compared to Lithium-Ion battery |
All-in-one Backup | ESS system is all you need, whether you want to use it for IT/any other sensitive loads and Lighting/home appliances load. It can handle every appliance perfectly without having to buy a separate unit for every backup need in the home. | Users need to buy different Inverter systems for IT equipment and lighting/home appliances load, which means double the cost. |
Looks | ESS looks stunning and modern and perfectly blends with any environment. Its beautiful design is difficult to match with any traditional inverter on the market. | Nothing can be as bland as a traditional Inverter. These inverters look really clunky and are so big that they are bound to look out of place no matter where you keep them. |
Size and Space | The sleek design of ESS ensures that less space is needed. No trolley is needed to stack the battery as is inbuilt inside the ESS. With sleek and elegant design, it can be kept anywhere in the house like drawing rooms | The tubular battery is very heavy and bulky, making it mandatory to change it every 2-3 years. This is quite difficult and cumbersome as it will need two people to hoist it, and if you have stairs, it will be 5difficult to get the 70 KG batteries inside for installation or repair. Additional trolley is needed to store the battery. |
Portable | ESS weighs just 25% of a typical lead-acid based traditional Inverter, hence, it can be used for multipurpose. If one is going out for a short trip, they can take the ESS with them and use its power to give back up to laptop, music systems, mobile charging, camping and all. It can run for up to 20 hours if fully charged. | Traditional Inverter and Lead acid batteries are very heavy and are not portable |
Compact, Safe, Reliable, Ease of Handling | The ESS set-up is clean and safe for everyone in the house. Contrary to the traditional inverter, there are no hanging wires and terminals with ESS which can be hazardous to the safety of children and pets at home | In most of the cases, when the user or dealer refills the battery water than after the battery is charged the water comes out and creates havoc as the water contains acid and the floor is damaged permanently. Hanging wires and terminals can be dangerous to the safety of children and pets at home |
No Maintenance/ Refilling Of Battery Required | ESS doesn’t require refilling as it has a rechargeable LiFePO4 lithium-ion battery. | Tubular batteries with traditional Inverters need refilling of water periodically and it must be done with distilled water each time. Since most consumers and dealers are unaware of this requirement, they frequently use alternative types of water, further shortening the battery’s lifespan. |
Spilling of Harmful Battery Water | ESS is based on LiFePO4 battery, which doesn’t require any harmful liquid refilling. It is easy to manage and replace, making it completely safe for kids and pets | Refilling of battery water can cause water spillage. This water contains acid, often damaging the floor. It is also hazardous for kids and pets, making it a non-family-friendly option. |
Charging Time | ESS gets charged in 3 hours as the Lithium Ion battery charges faster. It can be used 4-5 times a day. Ideal for areas with frequent power cuts, such as India. | Lead acid batteries, especially tubular batteries, take a minimum of 10-12 hours to charge. In winter, acid and water expand and contract, so they can be used only once during the day since the charging takes more time. |
Low Running Cost/ Low Consumption of Electricity | Since charging time of ESS is 1/4th that of a lead acid battery, it uses less electricity than traditional inverter by at least 30%.Being a smart inverter, ESS automatically chooses the best AC power source for battery charging and supporting load during the day, which lowers the power consumption for battery charging and lowers the cost of electricity. | Lead acid batteries, especially Tubular batteries, continue to charge even after being fully charged, which drives up the cost of electricity.Therefore, even when there are no power outages, traditional inverter uses at least 1 unit of electricity. The bigger size of Inverter/UPS even takes 3 to 5 units per day. |
Life of The ESS | ESS has long life of 7 to 10 years as Lithium ion batteries are required to change in 7 to 10 years. It has an extremely long lifespan (3000 cycles) due to a discharge rate of just 20%. | Due to the Lead Acid battery’s dependence on constant water filling, which the consumer cannot monitor, it has a much shorter lifespan than Lithium ion battery and needs to be replaced in every 2-3 years. |
Easy Installation | The Installation of ESS works on Plug and Play model which is completely hassle free for every household. | Need and engineer/expert for installation, connections and settings for Traditional Inverter with Lead acid/SMF batteries |
No Manual Settings | ESS requires no manual intervention, even when it comes to settings, making it hassle-free for everyday users. | Traditional inverters settings need to be set as per individual requirements, which means you are always in need of an expert. |
Switching Technique | ESS has a fast switching technology which is required by the IT equipment and the heavy machinery which gives them uninterrupted power to them in case if power cuts or power failures. Su-vastika uses advanced Static switches in its ESS that reduce switching time to just 2ms to 5ms, which is fast enough to prevent a computer and most sensitive equipment from resetting. | Traditional Inverter has long switching time which interrupts the working of equipment till battery mode is active |
Back Up Time | ESS’s unique Lithium Ion batteries takes significantly lesser time to charge. In other words, in situations where there are frequent power cuts, ESS will provide greater back up hours simply because of its ability to charge faster. | Lead acid based Traditional Inverter takes greater time to charge and still provides lesser back up time throughout the day. |
High Power Quality | When a load is connected, ESS produces pure sine waves with lower THD than traditional inverter. Due to the extremely low THD variance, ESS generates Pure sinewave output and pure power is continually maintained for IT loads like computers, printers, routers, etc | Traditional Inverters are available in Square wave or Sinewave. When a load is connected to an inverter, the THD always changes, which causes harmonics and is bad for sensitive loads, especially IT loads. |
Pollution and Health Hazards | Fitted with Lithium-ion batteries makes ESS more environmentally friendly as it can be recycled economically. There are no harmful fumes to worry about. The set-up is clean and safe for everyone in the house. | Traditional inverters emit harmful gases that pollute indoor air. It also ends up in landfills which causes land pollution. High-intensity fumes of lead can cause long-term diseases. Lead vapours from the lead acid battery are released in high concentrations when it is charged and discharged, making them extremely dangerous for children and adults. These lead vapours can cause long-term illnesses in people because they immediately enter the bloodstream and raise the level of lead there. |
Self Discharge While Charging | ESS has the new technology in charging. Lithium-Ion batteries are charged faster and once charged 100%, it does not need charging to maintain it to 100% as its self-discharge is very low as compared to Lead Acid battery. | The lead acid batteries specially Tubular batteries never stop charging even when they are charged so the trickle charging keep happening which increases the electricity bill and affect the battery life |
Full Capacity at Different Discharge Levels | The Lithium Ion battery enables ESS to run any load to its full capacity of 100% unlike | Lead-acid based Traditional inverters which if discharged at the rate of 50%, will give only 50% of its rated capacity. |
Self-Diagnostics | ESS provides a self-discharge measurement and a self-diagnosis feature which means no manual intervention is required. | No self-diagnosis mechanism, which means technicians might need to conduct multiple tests to even diagnose small errors. |
Bluetooth/Wifi (Optional) | ESS comes with optional Bluetooth/WiFi connectivity which allows remote monitoring & control. Using the dedicated app, you can now easily check your ESS status and monitor and control it even when you are away. One can also do Remote diagnosis of system by fetching the data through Bluetooth/Wi-Fi | Traditional Inverter has no Bluetooth or WIFI capability, which is really inconvenient for modern users. |
GPS | ESS has an optional GPS feature that makes it an Anti-theft product that is immune to theft, as you can find its location in real-time. | Traditional Inverter can be easily stolen when you’re away from home on vacation, or when you’ve left your home unprotected. There is no option to track it without GPS |
Remote Diagnosis | One can diagnose ESS system even remotely if you have your smartphone with you. With it’s Wi-fi connectivity feature and dedicated mobile app, you can monitor, diagnose and generate reports without having to be physically present. | There is no support for remote diagnosis, meaning whenever there is a problem with your Traditional Inverter, you have to be physically present to do any kind of diagnosis. |
Digital Warranty
Su-vastika brings in a Digital warranty for Inverters, a remarkable, revolutionary, and mindful innovation. Su-vastika’s Digital warranty is linked with the microprocessor in the PCB Mains card of complete range of Inverters, UPS, Online UPS, Solar Hybrid PCU, ERD, ESS.
The warranty shall start only when Inverter is connected to Battery, and when the Battery is disconnected from Inverter, the warranty stops. This addresses one of the common concerns with traditional warranty models. With this approach, the warranty remains valid as long as the Inverter is actively in use, regardless of the reason for its temporary disconnection, such as the Inverter or Battery not working or the owner being away on vacation.
The warranty can be accessed very easily by connecting your Inverter through Su-vastika Bluetooth/ WIFI app or via data transfer wire to computer.
The calculation of the Digital warranty provided by Su-vastika is based on a descending order system, represented in Moths, Days, Hours, Minutes, and Seconds.
