Good day all, the MPPT that was in my van when I bought it just crapped out at me. Since I'm replacing it, my partner has asked for something with an App. My question is, if I one like Victron or Renogy with the app built in, am I going to be locked into that equipment system? I'm going to be replacing batteries and panels down the road, but I'm on a very constrained budget so right now I'm looking for flexibility in component interoperability. #lifestyle source
