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).

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. 
1. Check that controller is mounted in a clean, dry, and ventilated area. 
2. Check wiring going into the charge controller and make sure there is no wire damage or wear. 
3. Tighten all terminals and inspect any loose, broken, or burnt up connections. 
4. Make sure LED readings are consistent. Take necessary corrective action. 
5. Check to make sure none of the terminals have any corrosion, insulation damage, high 
temperature, or any burnt/discoloration marks. 
For best controller performance, it is recommended that these tasks be performed from time to time. 
Risk of Electric Shock! Make sure that all power is turned off before touching the 
terminals on the charge controller.
