6. Troubleshooting and Support
High DC ripple is usually caused by loose DC cable connections and/or too thin DC wiring. After the inverter has switched off due to high DC ripple voltage, it waits 30 seconds and then restarts. After three restarts followed by a shutdown due to high DC ripple within 30 seconds of restarting, the inverter will shutdown and stops retrying.

How bad is it to undervoltage a 12-volt lead-acid battery?
You notice battery cells become sulphated when the battery voltage can be driven high and battery receives no current. Typically a healthy and slightly discharged 12V 70Ah battery drops to 15-20 Amps after a few minutes at 14.4V chharging. When sulphated You can apply 15-30V and barely no current flows at all. Then you are in trouble.
