Solis FlexHome Storage System 20kWh Low Voltage, 4 Modules with BMS
A complete Solis FlexHome system of 20kWh: 4 battery modules of 5kWh and the matching BMS control unit, under one order code. Nothing to piece together: a BMS without modules stores nothing, and modules without a BMS are not a system.
The modules stack, and the low voltage FlexHome range covers 5 to 40kWh in 5kWh steps, with up to 4 units in parallel. The cells are LiFePO4, rated for 100% depth of discharge and more than 6,000 cycles, about ten years of service.
A single module works at a recommended charge and discharge current of 50A, about 2,560W at 51.2V nominal, with a maximum discharge current of 100A; in a taller tower those figures rise with the module count. The complete system weighs 324kg, so handling needs planning. Installation and commissioning are work for a qualified electrician.
The complete system costs less than the same components bought one by one. To see each product on its own and get a quotation, visit SolarGear.eu.
