Build guides by use case
Solar setups by use case
Different setups have completely different requirements. A van solar system looks nothing like a cabin solar system; an RV with AC needs a whole different bank than one without. Pick the use case that matches yours for the honest build math.
Van life
2.4 kWh/day · 12V 200Ah · 400W array · the no-frills sweet spot
Off-grid cabin
5 kWh/day · 48V 10 kWh · 2 kW array · with honest generator backup math
RV / motorhome
2 kWh/day no-AC; 6–8 kWh/day with AC — two completely different builds
Tiny home / ADU
4–6 kWh/day · 48V 10 kWh · grid-tied or off-grid depending on the lot
Sailboat / cruiser
2 kWh/day · 12V 300Ah · 600W flex on bimini · with the salt-air gotchas
