4.3 Troubleshooting
If the following faults occur, check and troubleshoot as follows:

1. The number of
photovoltaic array series
groups is too large;
2. The charging end
voltage is too high;
1. Disconnect the photovoltaic array, reduce the
number of photovoltaic array groups in series, and
ensure that the open-circuit voltage of the
photovoltaic array does not exceed the set value;
2. Check the voltage of the charging end;
Battery over
voltage
(overcharge)
Ubat and the
icon
flicker
1. The overvoltage
protection point of the
lithium battery integrated
machine is below the
highest value of the
charging range;
2. Battery aging;
3. Large and dynamic
change of the load;
1. Remove the battery charging equipment first;
2. Battery aging needs to be replaced with the
battery;
3. Reduce the large and dynamic changes of the
load;
Battery under
voltage
(overdischarg
e)
Ubat and the
icon
flicker
1. The voltage value of
the lithium battery
integrated machine is
lower than the setting
value of the undervoltage
protection
2. Battery aging;
3. The battery is not used
for a long time;
1. Reduce or disconnect the load. If the alarm is
lifted, the battery voltage returns to normal,
indicating that the load power is large or the battery
voltage and capacity are low, and the heavy load is
easy to lead to the under voltage protection
phenomenon;
2. Disconnect the load lithium all-in-one machine
still alarm, the battery voltage is not restored to the
over discharge recovery set point, the need to
charge the battery pack through photovoltaic or
other ways, so that the battery pack voltage reaches
the recovery point set point before the fault is
removed,
Heat radiator
overheating

1. The ambient
temperature is too high,
the equipment heat
dissipation is poor, and
the fan ventilation is not
smooth; 2. The fan is
damaged
1. Check the installation environment of the
equipment, remove the debris of the air duct to
ensure the smooth ventilation of the fan; 2. The fan
is damaged, and the fan should be replaced;

If the reboot for several times can not be solved,
then return to the factory for maintenance;
