ESS Series Energy Storage System (5/10KWh)
ESS series for home energy storage

The ESS Series energy storage system is specifically designed for a family of PV generation system.

It can be use in the family with PV system and with tier electricity price, the ESS could improve PV self-sufficient rate during peak demands, save electricity bills.If there is PV and no mains supply, the system works in off-grid status to supply electricity power, it forms the uninterruptible power supply systems.At night, you can set the charging and discharging time by mains, charge the system at off-peak, and provide power supply at peak demand. The system work in off-grid mode, save electricity bills.
