alt Hacker NewsDo you have a website with your system on it? I have an off-grid building I need to add solar to in the next year or so. After I fix the foundation and roof, of course. Naturally I’m exploring options for item 387 on the todo list instead of think about how I’m going to jack the building up.
It's a pretty simple system:
4KW of panels, 400W 48V EG4 6000XP charge controller/ inverter 3x EG4 LifePower4 48V batteries a raspberry pi running solar assistant
I feels like a bit overkill, and there is still a whole mppt unused on the 6000xp so I could still double my panel input. Also solar assistant tells me that I rarly go below 75% battery storage. If I just wanted to run my fridge and assorted convenience loads (and ran things like table saws off a generator) then I could get away with a lot less of a system.
But I'm operating a recording studio, and there were a couple days this winter where I had a full-band session and a couple days of storms and got down to below 50%.
