How the System Works

During the Day

The 13.97kWp solar array generates electricity from sunlight.

22 × 635W Jinko Panels → SRNE Hybrid Inverter → Connected Loads

The solar energy can be used directly by the connected loads. Where solar production exceeds immediate consumption, available energy can be used to charge the lithium battery bank.

Evening and Night

When solar production decreases or stops, the system can utilize the stored energy:

33.4kWh Lithium Battery Bank → SRNE Inverter → Connected Loads

This allows stored solar energy to continue powering supported loads after sunset.

During a Grid Outage

The battery bank can provide backup energy through the hybrid inverter to supported loads, subject to the inverter’s rated capacity, battery state of charge and the specific installation configuration.
