I have been toying with the idea of supplementing my energy usage with solar panels. I have been studying costs and payback time and what I might need. I have been reading this forum for the last year to get ideas. Folks always recommend you do an energy audit to see how much energy you...

Just read this on my phone. I am surprised it is not being discussed here on the forum, or I am missing it? "California’s utility regulator unanimously voted Thursday to significantly reduce subsidies for rooftop solar installations, sparking outrage among solar industry leaders and marking...

I have been using the 120 amp Overkill bms for about a year now on a 12v 280 amp hr DIY battery with prismatic cells. No problems in the year I have been using it. I'm using the Android version. I have both the Chinese and the new overkill versions. For some reason, the blue tooth app in...

Has anyone used their super purlin beams to build a ground mount array? Think of using some of these to build an array. https://powerssolarframes.com/solar-purlin/

Please review this wiring diagram of my system and make any suggestions. I left out the 12 volt DC positive wires for clarity. Please excuse the rough artwork. ;) The inverter has internal bonding between the neutral and the chassis ground.

I finish my install and test it out in the winter sun.

Just uploaded a video detailing my installation of solar panels on my trailer roof. Total of 1480 watts worth of panels on a 7x16 trailer. I think I have the roof covered.

I am installing my 2200 watt Giandle inverter into my Toy Hauler project. I have hooked up my inverter hard wire output directly to my RV power distribution box to the same inputs as my shore power. My inverter only turns on if I press the on button, if the inverter is off and I connect to...

I have 2 brand new BoudgeRV 180 watt panels. Never used, decided to go with much larger panels. $200 for the two of them. Located 20 miles from Cookeville, TN.

I can drive to this location and pick up these panels. Will be putting 4 of these on my cargo trailer conversion. Any opinions on this deal? https://middletennesseesolar.com/product/340-watt-q-cell/

Can someone provide a website/link to a solar panel retailer in Central Tennessee or Florida? I will be traveling to the Tampa area and would like to be able to stop and maybe pick up some panels. When I search the web all I find are installers. I live in Central TN but I bet Florida would...

Anyone order from BougeRV? I ordered panels on 30 Nov and have only received one panel so far. They keep giving me excuses why I haven't received my second panel yet. Anyone have a similar story to tell?

I am installing some xt60 female connectors into the wall of my RV cabinets. Is there a cap I can buy that covers the connector when not in use? I can also use the male end after removing the wire portion of the connector but I thought there might be a product for that purpose.

Advice, experience with dealers selling Victron solar controllers. Specifically the smart solar 100 volt 50 amp model. Give me a recommendation for a good dealer. They all seem to be the same price.

I received the cells that I purchased thru Michael on the group buy. The vendor dropped the ball on shipping my cells and Michael delivered batteries from his own stash that he had ordered. If I had ordered on my own I would probably still be waiting for the cells! The next problem was they...

I know that using a state of charge is not accurate at all, but I need to have some idea of the state of charge of my new batteries. I just received my cells and the voltage reading is 3.274 volts. The sticker on the cell reads Capacity 280 Ah. Can someone give me the general state of charge...
