I don’t power all of it at once, and not direcly off of solar. I could maybe fit another 200W worth of panel on that roof, but for 4000W I’d need seven caravan roofs. That battery is the buffer and it’s a beast. At 300Ah I have 4kWh to pull at 1C.
The fridge sips a nice 30W. Panels put in ~2kWh on a sunny day. So thats a 1.7kWh surplus for running heavy loads - enough to max out that inverter for an hour a day. That’s plenty for microwaving or pumping water.

Sounds like a nice setup. I’m jealous :D
But shouldn’t that only be a 1.3kWh surplus with the fridge drawing 30W*24h=720Wh?
You’re right.
Well, still enough juice to pump all the water we need and heat our meals.
We’ll just have to limit hot showers to once a fortnight. Needs about 800Wh to heat the hot water tank.

I don’t mean to criticise but if you can add anything more (like the other 200w space) I suggest you should. 👍
