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.

StirCrazy, solar and batteries are kind of like fun, mayo and butter & sour cream - there's no such thing as too much. ![[emoticon]](http://www.rv.net/sharedcontent/cfb/images/smile.gif "smile")

We're currently camping near Bouse, AZ on BLM land. Our Victron solar controller app showed a solar harvest of 7.57 kwh yesterday. Had to cycle the electric water heater to maximize harvest. Typical TV, lights, res fridge, microwave and LP furnace blower loads.
