The Sofar energy storage kit, consisting of a Sofar HYD-10K-LT1 three-phase hybrid inverter rated at 10 kW and four SF-5KWH-L1 battery modules with a total capacity of 20.48 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-5KWH-L1 modules with integrated BMS provide a total of 20.48 kWh of capacity, and the storage can later be expanded to 16 modules connected in parallel (approx. 81 kWh). Together they form a modern system that increases energy independence and the security of your home's power supply.

The Sofar 10 kW + SF-L1 20 kWh kit includes:

• Sofar HYD-10K-LT1 10 kW hybrid inverter
• 4 × Sofar SF-5KWH-L1 5 kWh battery module
