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 load from the battery via the EPS terminals. Note: in off-grid mode, the
maximum system output power using only the battery is 5000W, meaning the load power of the
EPS circuit should not exceed 5000W. 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.
6.3.2 Fault State
The RX-7000HY/5000HY has a smart control system that continuously monitors and regulates
system status. When there is a system fault or equipment fault, fault information will be displayed
on the web page /APP, and the LED light will also be on in fault mode.
Notes：

When the system is upgrading firmware, do not power off the unit. When the upgrade is complete,
the system will automatically revert to normal working mode.
6.3.4 Self-check Status
Before entering normal operation mode, RX-7000HY/5000HY will enter self-check mode. If all checks
pass succesfully, the system will return to normal working mode; otherwise, the system goes into
the fault state.
6.3.5 Standby Status
When the system does not fault but certain operating conditions are not met, the system will turn
to standby mode.
6.3.6 Protection Mode
Connecting an oversize load to the EPS terminal will trip the unit and trigger protection mode. The
unit will try to restart 3 times, if the load is still present, the unit will revert to protection mode. Remove
the oversize load and restart the unit. If any circuit breakers have tripped – contact your installation
partner.
