Always refer to your controller''s manual for troubleshooting. At Solar Grid, our team ensures your system operates at peak efficiency, free from common issues like these!
For example, the controller may display an error code when the solar power it is receiving is insufficient to start charging the batteries. This is usually the case when the battery bank is partially discharged.
Disconnect the battery and reconnect it with the correct polarity (positive to positive, negative to negative). Error Code E04: Solar panel over voltage. Diagnosis: Check the solar panel
E04 indicates a load short circuit alarm. You can first follow the steps below to troubleshoot: 1 eck if the battery value appears on the controller load interface, and determine if it
This error shows when the charger is configured to be controlled by a BMS, but does not receive any BMS control messages. In that situation, the charger stops charging by reducing its
I bought a 300W inverter that I want to connect to the Load pins on the controller but when I do so I get a E04 error on the controller. It seems like this means "Output Short Circuit warning".
To reset the controller, you must reconnect all of its wires and make sure it hasn''t been bypassed. A few causes of this error code include reverse polarity, obstructions near the heat sink, or
E04 indicates a load short circuit alarm. You can first follow the steps below to troubleshoot: 1 eck if the battery value appears on the controller load interface, and determine if it
Explore our guide to understand solar charge controller error codes. Get reliable solutions for troubleshooting & quickly fix any issues.
Always connect the charge controller to the battery first. Then connect the solar panel to the controller, but only AFTER the controller has fully booted up on battery power.
