The Solis energy storage kit, consisting of a Solis S6-EH3P6K-H-EU three-phase hybrid inverter rated at 6 kW, three FlexHome 5 kWh-H battery modules with a total capacity of 15 kWh and a FlexHome-CB50A-H BMS control module, 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 inverter works with high-voltage (HV) LiFePO₄ batteries and offers efficiency of up to 97%, switchover to backup power in less than 10 ms, support for dynamic energy tariffs and peak shaving. The FlexHome 5 kWh-H modules, managed by the FlexHome-CB50A-H BMS, provide a total of 15 kWh of capacity, and their modular design allows the storage to be expanded to as much as 40 kWh in a single system. Together they form a modern system that increases energy independence and the security of your home's power supply.

The Solis 6 kW + FlexHome 15 kWh kit includes:

• Solis S6-EH3P6K-H-EU 6 kW hybrid inverter
• 3 × Solis FlexHome 5 kWh-H battery module
• Solis FlexHome-CB50A-H BMS control module
