B．Off - Grid / EPS Functionality
When the power grid is cut off, the system will automatically switch to off-grid mode. The system
will supply power to the EPS loads through the battery. Note: under off-grid mode, the system power
output rate only using the battery is 5kW. The load power rate of the EPS end should not exceed 5kW.
When the system detects a low battery status, the battery will stop discharging automatically and the
battery will be charged when there is solar or other power supply available.
