General troubleshooting
To make sure that the battery in your generator works correctly, it should be checked for its voltage. This is done by comparing the DC voltage readings on the battery and the generator's controller. If the battery doesn't measure as having at least 12.5 VDC, Give the battery 24 hours to charge.
- If charging for 24 hours does not resolve the issue, then the battery may require replacement.
- If the voltage is over 12.5 VDC, check the battery charger for proper operation.
Additionally, performing a hard reset may clear this error. See How Do I Perform a Hard Reset on a Home Standby System? for more information.
