over temperature
The solar charge controller limits the charging power to the
nominal value. Oversized PV systems cannot be operated
at maximum power.
overcurrent
normal working range (8.5 - 15.0 or 20 -
30.0 or 40 - 60.0 V).
Full protection against PV reverse polarity, no damage to the
solar charge controller. Correct the connection to resume
normal operation.
PV Reversal
short circuit
Check whether other sources are overcharging
the battery and whether the parameters
are correct. If not, the solar charge
controller is probably damaged.

Description
Battery polarity
When the battery is charged, the load
is switched on again.
Full protection against battery polarity reversal, no
damage to the solar charge controller. Correct the connection

Error Description
After the temperature has dropped
again, the solar charge controller works
normally again.
PV overcurrent
If a PV short circuit occurs, the solar charge controller will
stop charging. Fix the short circuit to continue normal operation.
The battery voltage Charge or discharge the battery is not in when
starting so the battery voltage is in
Reduce the load, the solar charge
controller will resume normal function
after one minute.
PV short circuit
battery overvoltage
Switch off all loads, eliminate short
circuit. Last is switched on again
automatically after one minute.
