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).
