Features Lithium Batery Freedom 40Kwh

Long Life High Performance Energy
The Freedom Lite Home and Freedom Lite Business range from Freedom Won offers the long overdue next generation energy storage with a quantum increase in service life and operational efficiency at a fraction of the lifecycle cost compared to other energy storage options.

Control Interface for compatible Inverter/Chargers
The BMS provides digital potential free contacts for independent control of the inverter load and the charge from the main charger and solar charge controller through a multi-pin plug on the side of the module, which also includes pins for voltage sense and charge current control for compatible chargers. The BMS is fully configured prior to delivery.

Power Interface
Positive and negative studs are provided for connecting the 48V DC cables to the inverter and solar charge controller. The DC circuit is protected with a shunt trip  circuit breaker.
