Left the rig for the night with just the fridge running and everything seemed fine, inverter was turned off. Put her back in storage and plugged her in under a roof. All other times the Zamp solar charger would go dark because being under a roof, but this time it stayed on, dimmer, but still on. This morning the Zamp was still on showing 12.8 volts while the inverter panel showed 13.5. I unplugged and drove for 20 minutes and both the Zamp and the inverter showed 13.0 amps. I have never seen my batteries (lithos) that low. It is back under roof and the Zamp is still on. Any ideas?

What were the circumstances on you running the generator? Was the coach sitting for a while? The 3200 watt onan should easily run the AC and the Microwave. I'm sure you would know if other heavy power items were plugged in. Were you using the induction range by chance? If not, and if your lithium batteries were really low (part 2 of your question), the charger is capable of sending 80 amps to your batteries. So if you had AC and your charger running at 80 amps, the microwave would cause the surge.
You mentioned you keep your coach plugged in, if so your batteries should have been about 13.4 volts. The zamp controller can stay on if you have slight light breeding through from your cover.
