Our B20K Energy Storage System is built robust using galvanized steel panels to protect against corrosion. The four castor wheels can be removed to install directly to a flat surface.
The B20K incorporates four banks of sixteen Lithium Iron Phosphate (LiFePO4) batteries, providing efficient storage, high energy output and long life.
Our B20K integrates BMS controllers to efficiently manage the charging/discharging and health of the internal batteries. They can be connected to an external Inverter for monitoring purposes and data read out.
The B20K battery does not support series connec- tions however, up to four units can be connected in parallel providing up to 80 KWh of stored energy.
Enerthium warranties our B20K for 3 years. The internal LiFePO4 batteries can be cycled (charged/discharged) 3000 to 5000 times and providing a lifetime of 7-10 years under normal use, when cycled daily.
