I’ve given this some thought with regards to small-scale off-grid solar and battery use. Last summer I installed 540Ah (12v) in a houseboat and was able to power a small air conditioning unit overnight to allow our family to sleep comfortably when the temps are >80F/26C. Most nights we would wake with about 40% charge, allowing us to cook breakfast on an induction cook top. At least in my small world of river glamping, having an efficient battery/solar/appliance system leads me to use and rely on it more. If you have it you may as well use it, especially if it’s renewable once it’s installed. This may all seem totally obvious but keep in mind one of the first steps to building out this kind of system is tallying up your intended energy usage. We didn’t “need” to have A/C but it makes the entire experience that much more accessible/enjoyable with small children in small spaces. The spreadsheet of usage can quickly snowball as watt-creep sets in and you think: “well if I’ve got this efficient refrigerator to store breakfast then I’ll probably need a kettle for coffee” etc. Can’t wait for summer!
