When Solar Generation Exceeds Load Demand

Jinko PV → Inverter → Battery Bank

Excess solar energy is stored in the 102.4 kWh lithium battery bank for later use.

During the Evening/Night

Battery Bank → Felicity Inverter → Loads

The stored battery energy can supply the loads after solar production decreases.

During Grid Failure

Battery → Hybrid Inverter → Loads

The inverter can provide backup power from the battery bank, subject to the inverter’s output capability and the connected load requirements.

When Battery Energy Becomes Low
