Input limit power protection
When solar panel power exceeds the rated power, the solar charge controller limits
solar panel power within the scope of rated power to prevent damage of the controller by
excessive current, The solar charge controller enters current limit charging.
Battery Reverse connection protection
When storage system is connected reversely, the system does not work and does not
burn out solar charge controller.
Photovoltaic input terminal voltage too high
Photovoltaic array input voltage is too high, and solar charge controller will
automatically cut off PV input.
Photovoltaic input terminal Short circuit protection
After short circuit of photovoltaic array input terminal, the solar charge controller
disconnects charging, and when short circuit condition is removed, charging will be
automatically restored.
PV input reverse connection protection
When polarity of photovoltaic array is connected reversely, the solar charge controller
will not be damaged, and will continue normal operation after correcting wiring error.
Warning: During reverse connection, battery voltage together with
component element voltage must be less than 150V.
Load over-power protection
