Go Green with a 20 KVA Lithium Inverter/Energy Storage System
A 20 kVA energy storage system (ESS) is a battery-based system that stores electrical energy from the grid or a renewable energy source, such as solar or wind. The system then delivers it back to the load or for on-site use when needed. The 20 KVA Lithium Inverter, which can be added to the solar system, has been a big competition for the Diesel Generator as it has very distinctive features compared to the Diesel Generator.
20 KVA ESS
ESS systems are becoming increasingly popular for a variety of reasons, including:
- Providing backup power in case of a power outage.
- Improving grid stability by helping to balance supply and demand.
- Reducing reliance on fossil fuels by storing energy from renewable sources.
- Saving money on electricity bills by taking advantage of time-of-use rates.
- Instant Switching: In case of grid failure, the instant backup is given by the Lithium battery
- The Saving of fuel bill: the generator need fuel which need to be refill and stored for the future usage whereas the Lithium ESS get the charge from the grid power or solar power and give the back up in case of power failure and does not require Diesel to fill as in the case of a diesel generator.
- No maintenance: the Diesel Generator need lot of Maintenace and need to change oils and filters after running of 300 hours of operation which is a big inconvenience for the user.
- Life of the ESS: The life of the ESS can be easily used for 50 years compared to the Generator life which is not more than 10 years. The Lithium battery will be replaced after every 7 to 10 years which is very cost effective compared to the fuel cost which is spent for running the Generator.
A 20 kVA ESS is typically sized to provide backup power for a small business or home. It can also store excess solar energy generated during the day for use at night.
Here’s a breakdown comparing a 20 kVA energy storage system (ESS) and a 20 kVA diesel generator for backup power:
Environmental Impact:
- ESS: Clean, silent operation with no emissions. Ideal for urban environments or locations with strict emission regulations.
- Diesel Generator: Produces air and noise pollution. May require permits or regulations depending on location.
Running Costs:
- ESS: Lower ongoing costs. Once installed, the main expense is electricity for charging (potentially offset by renewable sources) and occasional battery replacement.
- Diesel Generator: Higher ongoing costs. Requires purchasing and storing diesel fuel, which fluctuates in price. Regular maintenance is needed.
Maintenance:
- ESS: Relatively low maintenance. Mostly periodic checks on the system’s health.
- Diesel Generator: Requires regular maintenance (oil changes, filter replacements) to ensure reliable operation.
Power Delivery:
- Instant Power: Provides near-instantaneous power backup during outages.
- Diesel Generator: Has a lag time (around a minute) before starting to deliver power.
Scalability:
- ESS: This can be easily expanded by adding additional battery modules.
- Diesel Generator: Adding backup power requires purchasing a larger generator.
Other factors:
- ESS: May have a higher upfront cost compared to a generator.
- Diesel Generator: This may be a better option for areas with frequent, long-duration outages due to longer runtime on a single fuel tank.
Here’s a quick decision chart to help you choose:
- Choose ESS if: Environment, noise, and ongoing costs are priorities. You have access to reliable grid power for charging and have limited space for fuel storage.
- Choose a Diesel Generator if: Upfront cost is a bigger concern, and you experience frequent, extended power outages.
Ultimately, the best choice depends on your specific needs and priorities. Consider consulting a qualified installer to discuss your situation and determine the most suitable backup power solutiou.
Here are some of the key components of a 20 kVA ESS:
- Battery bank: This is the heart of the ESS, and it stores the electrical energy. Lithium-ion batteries are the most common type used in ESS systems due to their high efficiency and long lifespan.
- Inverter: The inverter converts the DC (direct current) electricity stored in the battery bank into AC (alternating current) electricity used by appliances and electronics.
- Charge controller: The charge controller regulates the flow of electricity between the battery bank and the grid or renewable energy source.
- Monitoring system: The monitoring system allows you to track the performance of your ESS, including the state of charge of the battery bank, the amount of energy being stored and used, and any system faults.
