PV array properly
PV array
open-circuit
Confirm whether the
connection of the PV array is
correct and tight
The wire connection is correct;
the controller is not working.
The battery
voltage is lower
than 8V.
Please check the voltage of
the battery(at least 8V voltage
to activate the controller).

blink
Battery over
voltage
Check whether the battery
voltage is higher than OVD
(over voltage disconnect
voltage) and disconnect the
PV array connection.
Battery over
discharged
① When the battery voltage is
restored to or above LVR(low
voltage reconnect voltage),
the load recovers.
② Other ways to recharge the
battery.
Battery over
heating
While the battery temperature
decline to 55°C or below, the
controller resumes work.
Load O LOAD OFF Overload
① Please reduce the number
of electric devices.
② Restart the controller or
press the button to clear
faults.
Load and Fault Load short-circuit
① Check carefully loads
connection, clear the fault,
② Restart the controller or
press the button to clear
faults.
① When the load current goes higher than 1.02-1.05 times, 1.05-1.25 times,
1.25-1.35 times, and 1.35-1.5 times the rated value, the controller may
automatically turn ooads in 50 seconds, 30 seconds,10 seconds, and 2
seconds respectively.
