How many kilowatt hours per day do you need is the place to start to size the system and battery storage.
I have a small system capable 4 kwh avg daily production with 5 kwh usable battery storage.
It's hybrid off grid/on grid.
Quoting: Remedial_Rebel We're looking at 5300watts off grid. Have 3 main areas to split that power. Aside from water which is covered separately. I'm thinking of dividing the panel powers into separate banks. It's enough to cover us according to our electric bill, but I'm thinking of doing 3 separate systems in effect to make sure we're good. Is that foolish? There's the barn...low except for occasional welder use and a big freezer. Then the enclosed greenhouse which is all to shade tolerant plants and a small aquaponics system, then the house, which is the main digs. Redundancy is a very good idea, but I would have a single system, with replacement components to have the most power available. Appliances like a refrigerator draw about 100w running but surge up to 1000w when starting up. I went with a 3000w/6000w off grid inverter. When you say 5300watts, is that solar panel power? That's not the same as average daily kwh production or need. What is your electric bill monthly kwh usage divided by 30 to get daily kwh usage. My 800w of panels produces 2.5 kwh of power avg per day. Your usage is more important to know than total panel output. Average usage across a year is 600 kw. This doesn't include switching to a attic fan instead of Ac..Not yet. But we can be hot. Imo...Better to be hot than cold. My question lies really in splitting charge controllers across a system. I think. Batts would be lead acid. I have a few gel, but those are committed to the water supply. If you mean 600 kwh per year, that's 1.6 kwh per day. That's a really light load. 800w of panels and 6 golf cart batteries (6v) would I think do the job. I would have a 4000w/2000w continuous inverter, 60 amp charge controller, too. 1 another factor to look up is the avg amount of sunshine you get where you live and a 100w produces on avg. Good luck.
