System Status Troubleshooting
PV indicator
Troubleshoot
Off during
daylight
Ensure that the PV wires are correctly and tightly secured inside the
charge controller PV terminals. Use a multi-meter to make sure the
poles are correctly connected to the charge controller.
BATT Indicator
Troubleshoot
Solid orange
Disconnect loads, if any, and let the PV modules charge the battery
bank. Use a multi-meter to frequently check on any change in battery
voltage to see if condition improves. This should ensure a fast
charge. Otherwise, monitor the system and check to see if system
improves.
Solid Red
The controller will have cutoff the output of the battery to ensure that
it charges. Make sure there are no excessive loads and give the
system appropriate time and sunlight to charge. Monitor readings
with a multi-meter to see if they system improves. If system does not
charge, then the user must find another means for charging battery
since it is too low for the controller to register.
Flashing Red
Battery is over-temperature and must be secured in a cooler
location. Disconnect PV panel(s), then disconnect the battery before
changing the battery’s location to a cooler area.
Quickly flashing
green
The battery voltage is higher than the over voltage disconnect. Use
a multi-meter to check the battery voltage to determine whether it is
too high. Then disconnect and reconnect the PV modules.
Work Mode
Troubleshoot
All LED flashing
(battery LED

The temperature of the controller is too high and is probably
exceeding 85
o
C. The controller will automatically cut the input and
output of the circuit. Once the controller registers a lower
temperature, it will resume functioning normally.
All LED flashing
(battery LED
red)
This indicates a system voltage error. Check whether the battery
voltage matches the controller’s working voltage. If correct,
disconnect and reconnect all connections. Solar modules are first
when disconnecting and battery is first when reconnecting.
