Faults Possible reasons
The LCD is off
during daytime when PV
sunshine falls on PV disconnection
modules properly
1) Battery voltage is
lower than 9V
Wire connection is

Troubleshooting

array Confirm that PV wire connections
are correct and tight
1) Please check the voltage of
battery. At least 9V voltage to
activate the controller
2) Check the PV input voltage
which should be higher than
battery's
Check if the battery voltage is
higher than OVD point (over
voltage disconnect voltage), and
disconnect the PV.
When the battery voltage
restored to or above LVR point
(low voltage reconnect voltage),
the load will recover
The controller will automatically
turn the system off. But while the
temperature decline to be below
50 ºC, the controller will resume.
Please reduce the number of
electric equipments or
carefully loads connection.
