Solar Hybrid PCU MPPT 2.5KVA Mobile Application

What is solar hybrid PCU having MPPT technology. https://suvastika.com/what-is-ai-based-solar-pcu-and-how-does-it-work/

Su-vastika 2.5KVA Solar Hybrid PCU with MPPT integrated with Bluetooth and Wi-Fi connectivity, designed for smart energy management and user-friendly control via a dedicated mobile app:

Key Features of the 2.5KVA Solar Hybrid PCU:

1. MPPT Solar Charging:
   • High Efficiency: MPPT (Maximum Power Point Tracking) optimizes solar panel output, ensuring up to 30% more energy harvest compared to PWM controllers.
   • Fast Charging: Faster charging of the batteries compared to the PWM Charge controller
   • Wide Voltage Range: 2.5KVA comes in 24V and 22V model which can take up to 110V from the solar panels. It can support 1000 Watt solar panels which is ideal for Lithium battery 2.4KW capacity or Tubular Lead Acid battery 200Ah capacity 2 numbers.
     

     Solar PCU 2.5KVA solar panel connectivity. It can be connected with 540Watt panels as well.

      

2. Hybrid Power Management
   • 4-in-1 Operation: Seamlessly blends power from:
     • • Solar priority: When the battery is charged to a certain level the load will be shifted to the Solar power even the grid is available so that the power bill can be saved during the solar sunshine.
       • Grid Bypass: The grid will be by passed when the battery is being charged through the solar power so that battery can charge faster and shift the power to solar energy. Bypass of Grid and charging is also done through the grid mode as solar is not available.
     • Battery and Solar Power for Backup: In case of power outages the systems work on battery or solar mode or both on battery and solar power depending upon the solar availability and battery power and load being run on the system.
     • When there is no Solar Power and the system is working on Mains (Grid) mode, then the Solar PCU will Bypass Mains (Grid) to flow directly to the Load and use Mains (Grid) to charge the battery.
       

       Overload Status

     • The Grid and Solar Sharing for Charging: Depends on the solar power availability and battery charged condition, If the battery is not charged properly and solar power is not sufficient to charge the battery then the Grid power will also start charging the battery along with the Solar Power so that battery remain in charged condition in case of power failure.When Mains and Solar are both available, the Solar PCU will use the following logic to determine which source to use for battery charging:
       • If the Mains(Grid) is available and the solar panels generate low current than the set charging current for the battery charging, then the Solar PCU will take the remaining current from the mains(grid) for charging the battery. It is called Grid sharing with Solar energy. For example; if the set charging current is 15A and solar panels generation is 10A then the remaining 5A current will take from Mains(grid).
       • If the mains(grid) is available and the solar panels are producing more current than the required current by the battery for charging, then the Solar PCU only use the solar panel’s current to charge the battery.
       

       Solar & Grid Charging Mains Mode

   • UPS Functionality: Instant switch to battery mode during grid outages (<5ms) for uninterrupted power to critical loads. So all computers and TVs will not be switched off during the load shedding or switching from Solar to Grid mode or vice versa.
