    Solar for my airplane trailer

    Well I have 32 AH, so that should be plenty. And parked out on the concrete ramp here in full sun, I'd guess we're talking eight hours per day, not three or four.

    Help me design a LiFePO4 battery for my homebuilt airplane

    I'm trying to absorb all of this (remember I'm an idiot) so this is really a place-keeper reply and I'll come back with something more substantial shortly. My plane has foldable wings and will live in a 20-foot enclosed car carrier trailer with its own 12V solar system including a 30 amp-hour...

    Solar for my airplane trailer

    Thanks for all the help. In practice, with so much solar being installed in California, it's often a matter more of what you can pick up on Craigslist than anything else. Find the best deals then choose among them to best match (over-match in this case) your needs. I got a 100 watt solar panel...

    Help me design a LiFePO4 battery for my homebuilt airplane

    I have a homebuilt airplane, a Thorp T-18C, which carries two people and has a Lycoming IO-320-B1A engine rated at 160 hp. I'll shortly be getting it back in the air following a six-year rebuild (the plane was originally built in 1999). It needs a new 12V battery (for starting, radios, etc...

    Solar for my airplane trailer

    Well, it's a white trailer and the goal is just to keep the inside temperature around ambient (that is, if my plane even survives, since we were just evacuated from the Kincaid fire). Still, you could be correct about the system size. I'm a newbie and Bluetti was for me just an example of an...

    Solar for my airplane trailer

    Even this seems a bit much, though you are right that I don't need the inverter. I fly at most twice a week and there is zero shade where the panels will be mounted so there should be plenty of time for charging and battery recovery. The empty weight of the plane is only 900 lbs so it's more...

    Solar for my airplane trailer

    I have a 20-foot enclosed car carrier that I use as a sort of hangar for my homebuilt airplane (a Thorp T-18) that has folding wings. I pay for a $40 per month tie-down at the local airport rather than for a $400 hangar or space in someone else's hangar. Now I want to add a simple solar system...
