The Sofar energy storage kit, consisting of a Sofar HYD-8K-LT1 three-phase hybrid inverter rated at 8 kW and a SF-16KWH-L1 battery with a capacity of 16 kWh, is a complete solution for residential photovoltaic systems. The system efficiently stores surplus energy generated by the PV installation and makes it available during peak demand hours, increasing self-consumption and reducing the amount of energy drawn from the grid.

The LT1 series inverter works with low-voltage (LV) 51.2 V LiFePO₄ batteries and offers efficiency of up to 97.6%, BACKUP power with a switchover time of approx. 4 ms, short-term overload of up to 200% of rated power for 10 seconds and the option to work with a generator. The SF-16KWH-L1 battery with integrated BMS provides 16 kWh of capacity, and the storage can later be expanded to 16 batteries connected in parallel (up to 256 kWh). Together they form a modern system that increases energy independence and the security of your home's power supply.

The Sofar 8 kW + SF-L1 16 kWh kit includes:

• Sofar HYD-8K-LT1 8 kW hybrid inverter
• Sofar SF-16KWH-L1 16 kWh battery
