    Combiner Sizing

    I have 6x 200w, 20.4Vmp, 9.8a Imp and 6x 100w, 18.5Vmp, 9.8aImp. The online calculator for 3s4p shows that there will be 1687W, 55.5V and 30.4 amps going to the MPPSolar LV2424 once I combine it all. I am trying to size the combiner to support it. It would be easier to buy pre made but I am not...

    More 12v vs 24v system discussion

    Hi, I am in experiment mode on a small 12x16 shed that I have set up very minimal electrical usage in preparation for a total off-grid 600sf cabin. It has 12v USB charging ports, lights and a small 12v Cosco fridge. There are a couple rarely used 120 AC outlets. I have 2 12v Lead Acid batteries...

    24v Battery bank on 120v Cabin

    I am getting close to pulling the trigger on some 12v batteries for a new 600 sq ft totally off grid cabin I am building. I was working towards a 24v setup by purchasing the MPP Solar 24v charger/inverter with a 24v to 12v stepdown for my shed with lights and a Mini Cosco refridgerator. Works...

    24v to 12v

    Hi, I recently added an mpp solar All in 1 24v converter/inverter. I reconnected my 4x12v Lead Acid batteries to 2x 24v batteries. That's working well. I did have to buy a 60w 24v to 12v 5A reducer for the preexisting cabin wiring Some lights, USB charging ports for my phone and a Costway DC...

    MPP Solar LV2424: 120v cycling

    I just installed my MPP Solar LV 2424 with 4 12v sealed Lead Acid batteries. I have a 24v to 12v converter to run my existing 12v load. I noticed yesterday that when I was trying to charge a Milwaukee tool battery and then today when I was charging my computer, the power was cycling on and off...
