I was checking the voltage, but using the Xantrex Inverter display. It was 12.3 which I thought would be enough. But it's worth double checking. Thank you!
Yeah, don't go by that display. Disconnect house battery and check there with a meter. 12.3v at your battery would indicate its not charging to capacity any longer. Should show closer to 14v.
