Using a multimeter check the battery voltage and verify it is not

exceeding 32 volts.

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.

The Load circuit on the controller is being shorted or

overloaded. Please ensure the device is properly connected to

the controller and make sure it does not exceed 20A (DC).
