Troubleshooting
Check that PV and battery wire connections are correct and
tight.
Please restart controller;
if the fault still exists, switch off controller immediately and
contact the supplier to make maintenance.
The controller cut off the output automatically and recover when
fully charged.
switch off the wiring of solar array and measure the voltage of
battery whether is too high.
When operating ambient temperature or battery temperature
reaches exceeds 65º C controller will cut off input and output
circuit automatically.
When the temperature
automatically reconnect input and output circuit.
Check whether the battery voltage is consistent with the system
voltage set by the controller.
①Please reduce the number of electric equipments.
②Restart the controller.
①Check
carefully loads
②Restart the controller.
Please restart controller, if the fault still exists, cut off charging
is below 55℃, controller
connection, clear the
will
fault.
