  • Debating all-in-one vs charge controller+multiplus...

    I'm building out my second rv system and I'm planning to with two (2) 48v solar rack batteries paired with 2200w of panels (Renogy 550w). Originally I was going to do a separate Victron charge controller paired with the Multiplus II. However, now I am wondering if an all-in-one (EG4) is a better...

  • Any third-party software available for MPP solar systems?

    I have the MPP Solar 2424LV-MSD, and while it's been great so far, the software is just...well not so great. For one, the mac app doesn't seem to work no matter what I do. The windows app is fine, but I don't use windows very often. I would love something else that is more modern and...
  • Random clicking coming from MPP Solar 24V system. Is this normal?

    Every few hours, there is this clicking sound coming from the inverter. It sounds the same as when you turn the inverter on or off and the click you hear when it initiates, but I think it's a little louder. It may be a surge from the fridge (though I can't hear when the fridge kicks on), but it...
