StirCrazy, I understand about the bar fridge, but there are other advantages to upgrading solar and batteries. We started out with 1200 watts solar and 618 ah of LFPs. Then added 400 more watts, then I added 2 more LFPs. I'm about maxxed out, not much room on the roof for more solar and adding more would require a controller upgrade.
oh ya definatly, I have three 180 watt 12V panels on the fith with a PWM controler and four 6V batteries so a usable 200ish AH. when I do that upgrade I am going to switch to three 350ish watt 24V panels MPPT controler and then Ill put about 900AH of LFP in there. I figure that battery capacity will give me about a 9-10 day reserve at my current usage, or once I start running the bar fridge that could drop down to a 3-4 day reserve if the solar ***** out. the increase in solar should put me up to around 60 amps or more of charging for the good 4 or 5 hours so thats more than enough to charge and run the bar fridge through the day. I do have the advantage of not needing my AC and a lot of the 120V stuff in normal situations. I carry two coffee pots a perculator and a kieurg, a regual toaster and a camp stove toaster and so on so if we are having issues with power it isn't a hardship to reduce my power usage.
