Okay, I'm working with a 2020 T@B 320S Boondock with a solar panel from the factory. I'm still using the original 70ah wet battery.
I'm finding that the solar from factory is enough to support the fridge on a low setting in Spring and early summer. Later in the year, or in shaded locations the fridge will pull that battery down below 12v over night. This should surprise no one here, I'm sure.
I'm considering buying an inverter generator to supplement the electricity and allow the occasional microwave use while boon docking. The models I've been looking at are: Energizer EZV2200P or the Champion 1600W / 2000W Inverter Generator.
This is all well and good BUT...
1. If my battery is down 50% (or to 12v) and I plug in the inverter generator to the trailer, how long will it take to charge the battery back up? An hour? Two hours? 10?
2. Is there a better way? Should I be plugging a battery charger into the inverter generator and boosting the battery directly?
Any thoughts on this are appreciated. We are just looking at keeping the fridge running and enough power to run the tap now and again. When day length is limited we aren''t at that level right now. I know a change of battery is probably warranted, but one small step at a time.
Thanks for your help.
