@Vtecvfr Cool, I would manually set state of charge to correspond to the battery voltage as it is now, so 40%? and then put the genny on in the morning if possible and run until either the sun can finish off charging from 85% to 90% up, or leave the genny on for longer. Ideally you want to get it back to 100% but that''s ideally an 8-12h charge for FLA''s.

The CC voltage with the "Dead Battery Signals" disabled is 0.432V, as would be expected with a 5.1k Rd. With "Dead Battery Signals" enabled, this voltage goes up to 0.644V and the TYPEC_VSTATE_CCx registers start reporting erroneous values (ie: not vRd-USB, as per table 428 in RM0440). I then measured the voltage when the MCU was unpowered.
If the charge controller is an MPPT type, it will require a panel voltage of around 6 volts higher than the batteries maximum voltage (14.4V maximum in the battery, therefor 20.4V minimum panel for example). If the charger is a PWM type, you should use a panel with an output Vmp around the same as the battery max voltage.
By checking your inverter battery voltage, you can detect signs of undercharging or overcharging. If the voltage is too low, it indicates that the battery is not being charged properly, potentially leading to sudden power failure when you need it most. Ensure the probes are firmly connected to the terminals to avoid inaccurate readings. The

But interestingly is the DC voltage goes up back to where it should be as well hmmm. The voltage on Aux 1 and Aux 2 is 4.91 volts pin 1 to pin 5 when O/C Aux 2 has a voltage of 113mv pin 2 to pin 5 and 4.91 when O/C or the ac sensor removed. If I check when the RJ12 is plugged in then its 0.00 on Aux 1. Pin 1 is Aux 1 high. Pin 2 is Aux 2 high

Tests fail when the cranking amperage and/or voltage, along with other criteria, are less than the criteria inputted into the test equipment. That should be a clear-cut case of a bad battery, but that's not always true. It's possible for a result of “replace battery” even if the engine still cranks and starts.
You can accurately diagnose battery-related sensor problems by following a systematic approach that includes visual inspection, voltage testing, and diagnostic scanning. Proper diagnostics ensure accurate identification of issues and help in making informed repairs. Visual inspection: Begin by examining the battery and its connections.
