The Lion Sanctuary System is a powerful solar inverter and energy storage system that combines Lion''s efficient 8 kW hybrid inverter/charger with a powerful Lithium Iron Phosphate 13.5 kWh battery. The combination provides for true energy independence whether you are on-grid (metered or non-metered) or off-grid.
The battery voltage depends upon the system power level. Lower power single phase systems commonly use 48-V battery, while higher power three phase systems use 400-V battery. Intermediate battery voltages are used infrequently. Systems with higher power range of string inverters could use 800-V battery for storage.
