Thoughts on EcoFlow refurb batteries/power stations for an offgrid cabin?
My offgrid cabin currently runs on a modest 12v solar setup with three 200Ah AGM batteries that are starting to lose capacity. I’m considering switching to lithium instead of replacing the AGMs. A friend mentioned EcoFlow refurbished batteries on eBay.
Has anyone here used EcoFlow refurb batteries long-term in an offgrid setup? Worth it, or would I be better off going with new LiFePO4/server rack batteries instead?
The system is fairly small and currently powers lights, a television, and Starlink, with plans to add a high-efficiency fridge. The cabin is mainly used on weekends and extended hunting trips.
I’m located in the Northeast, so winter performance matters since temperatures can get brutal. Right now I’m running 4×100W ground mounted panels, though I’m planning to upgrade to a larger roof mounted array in the future.
