extremely cool! How easy was it to disconnect from the grid? What's your city/county? Also, just curious, why did you decide on NiFe? Most off-grid folks I know

extremely cool! How easy was it to disconnect from the grid? What's your city/county? Also, just curious, why did you decide on NiFe? Most off-grid folks I know either use li-ion for density or lead acid for cost/abundance/ease-of-use.
> At 2pm I have more power than I know what to do with, I could happily run 3kw load for a few hours most days around that time.
A fun and interesting problem to have. This is why we need so much more research into energy storage.
- adamcharnock 7y agoI've moved to rural Portugal (from London). I would have to get the grid extended to my place in order to get grid power, and I was quoted at around €30k. I realised that for a fraction of the price I could get a pretty beefy solar system (and – you know – free power thereafter). I went for NiFe batteries because they they are basically impossible to break. This is my first system, and I wanted to take the reliable and stress-free path. Space wasn't a concern. NiFi batteries also last circa 40 years, so the price per year is actually very cheap. However, my planning horizon is definitely not that long.
