What did you leave on while gone,
Residential fridge?
Heater/furnace set to high, something sucked all those ampHrs from the batteries,
Yes properly charged batteries would have faired better, but something used that power,
Solar was not enough to resupply the batteries
Leaving the inverter turned on with no load will drain the battery as will the refrigerator on propane. The batteries will also self discharge if left for a while.
I disconnect my batteries if they are going to be idle for long. I have a "battery tender" coming to keep my brand new batteries healthy through the Winter.
