- Compatible with lithium-ion and lead-acid batteries
Product Overview
The Solis S5-EH1P5K-L works as a grid-tie inverter for self-consumption, directing solar energy to household loads, then battery storage, then grid export. When the grid fails, the inverter switches to backup mode within 20ms, supplying up to 5kW from battery and solar to critical loads. A changeover switch is required for the off-grid backup output.
The intelligent EMS continuously optimises energy flow, allowing users to select operating modes based on electricity tariffs, consumption patterns, and battery state. The 24-hour management function monitors PV plant status in real time and adjusts automatically to changing conditions.
