The Solis Elite HV energy storage kit, consisting of a Solis S6-EH3P40K-H three-phase hybrid inverter rated at 40 kW, four FlexCore-ID 20 kWh battery modules with a total capacity of 80 kWh and a FlexCore-ID 250A BMS module with a mounting accessory package, 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(30-50)K-H series inverter offers efficiency of up to 97.8%, four independent MPPT trackers, support for dynamic energy tariffs and parallel operation of up to 6 inverters. The FlexCore-ID 20 kWh modules with 314 Ah LiFePO₄ cells, managed by the FlexCore-ID 250A BMS, provide a total of 80 kWh of capacity at up to 100% depth of discharge and more than 8,000 cycles. Each module has a built-in fire suppression system; a cluster can be expanded to 13 modules (approx. 261 kWh) and up to 6 clusters can be connected in parallel (approx. 1.5 MWh). The system is designed for indoor installation. Together they form a modern system that increases energy independence and the security of the site's power supply.

The Solis 40 kW + FlexCore-ID 80 kWh kit includes:

• Solis S6-EH3P40K-H 40 kW hybrid inverter
• 4 × Solis FlexCore-ID 20 kWh battery module
• Solis FlexCore-ID 250A HV BMS module
• Solis FlexCore-ID mounting accessories (Accessory Package 1, 3–4 modules)
• 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.
