I haven't tested the batteries, so it's possible we either got a bad original set from Airstream factory, or our initial weeks-long dealer service visit allowed them to deplete through neglect.



My estimate of State of Charge is coming from the voltage reported by the Magnum and confirmed by the Victron bluetooth app. I'm assuming that 12.0 or so volts means I'm down to 50% SOC. I realize this is not resting voltage, so maybe I'm underestimating SOC.



How much current does the Nova Kool frige/freezer draw? I have separate units (not sure about the model number). It's a 2017 van.

TAYARA - I think the unit in you GT is a Nova Kool RFU6200. If so it draws 5.2A when the compressor is running. That is based on this spec sheet.

If you van sat for weeks on a dealer lot with no charging with stock setup the original batteries might be damaged. Also you Fusion may still be drawing power as many have reported on this forum. That would draw down the batteries too.

The only way to know what's happening on the load side is to have a shunt based current meter that measures all current flow into and out of the house batteries. I think they can be added to the Victron solar controller. I have one on my BlueSky controller and it is very helpful for monitoring battery health and status.

Thanks. At some point in the future, when the batteries age, we will upgrade our system. There are no AI electrical specialists here in Houston, so we'll need to schedule a trip around it. Things are working now, and we can go one night off grid with no problem. More would be nice, but we can live with and enjoy what we have.

It’s on the name plate on the inside left on both units
