The Solis Elite HV energy storage kit, consisting of a Solis S6-EH3P20K-H three-phase hybrid inverter rated at 20 kW, eight high-voltage FlexHome 5 kWh-H battery modules with a total capacity of 40 kWh and a FlexHome-CB50A-H BMS control module, is a complete solution for photovoltaic systems in businesses, commercial buildings and farms. 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 Solis S6-EH3P(12-20)K-H series inverter offers efficiency of up to 97.7%, four independent MPPT trackers, switchover to backup power in less than 10 ms, support for dynamic energy tariffs and parallel operation of up to 6 inverters. The LiFePO₄ FlexHome 5 kWh-H modules, managed by the FlexHome-CB50A-H BMS, provide a total of 40 kWh of capacity at up to 100% depth of discharge and at least 6,000 cycles. This is the maximum configuration of a single FlexHome system (8 modules), and IP66 protection allows indoor and outdoor installation. Together they form a modern system that increases energy independence and the security of the site's power supply.

The Solis 20 kW + FlexHome 40 kWh kit includes:

• Solis S6-EH3P20K-H 20 kW hybrid inverter
• 8 × Solis FlexHome 5 kWh-H battery module
• Solis FlexHome-CB50A-H BMS control module
• iONTEC Connect V2-R1-P02++ EMS energy management system

The iONTEC Connect EMS energy management system combines the PV installation, energy storage and loads into one intelligent system. It automatically decides when to charge and discharge the battery, uses dynamic RCE energy prices, limits grid export and controls selected loads. As a result, it increases self-consumption and lowers energy costs – without manually changing inverter settings.
