I installed this on a 1k solar panel powering an offline/grid shop. It powers all my LED lights and chargers with 2 deep cycle batteries. I would do it again and it works great. I got the software working on a laptop in 2019 and it sucked. If they haven't updated it don't buy it and think the software is amazing because it was hard to set up and useless once I did. But a 100 amp block is reliable. I don't even think about it. the thing just works. And that's how I like it.
