Invertor power consumption
My new to me RV came with a xantrex freedom 458 invertor with two new 8D AGM batteries.I set the panel for that type of battery. How long should those batteries last with a tv and fan going? The reas...

I disconnected the power and it dropped down to 12.5 amps on the display panel. I had set the incoming charge to 10 amps. I'll leave the invertor on overnight and see if the batteries drop further with the power unplugged.
The charge level should be at much more than 10 amps, that might be your problem.
Set the incoming power supply at 15 amps, and let the charger run at 100% charge rate. Or set the incoming power at 30 amps.
The charger plugged in - the battery voltage should be 13.5 volts or slightly higher.
If you only have the charger set at 10 amps max, then you might not be charging at all! It would take a long time to refill a pair of 200 AH batteries at only 10 amps per hour, and having draws coming from the batteries during that time.
Also the 100 watt solar panel is barely enough to keep up with the draws from the CO detector and propane leak detector. Together they can draw 0.8 amps, or about 20 AH daily.
I had friends with the Trace 458 inverter, and they accidentally set the incoming power level to only 5 amps. When more than 5 amps was passing through the inverter, then it would stop charging. By leaving it at 30 amps, everything worked normally again.
Good luck,
Fred.
