Fault State; Firmware Update; Self-Check Status; Standby Status - Redx RX Series User Manual

2．Anti-backflow function disabled:
In Auto Mode – the unit can provide power from the Grid and EPS terminals to any loads (max
2500W).When the system detects that there is excess power available from solar and not being
used by the loads and the battery is full, then power can be sent to the grid. In VPP mode:
RX-2505PW works as per the commands sent from the cloud platform. The unit can be fully
customised with charging times and discharging times and set power levels in Timed mode.
B．Off - Grid Functionality
When the power grid is cut off, the system will automatically switch to off-grid mode. The system
will supply power to the load from the battery via the EPS terminals. Note: in off-grid mode, the
maximum system output power is 2500W, meaning the load power of the EPS circuit should not
exceed 2500W;
When the system detects a low battery status, the battery will stop discharging automatically and
will be charged if there is solar or other power supplied.
