Adding solar to your RV can be simple and affordable

Greetings Again, Just started watching your channel and you are very helpful.... Thanx, -keith

I bought 8 250 watt solar panels used in Portland Oregon for $85 each! Craigslist. I will hook this up with a MPPT controller, that can accept up to 150 volts or 300 volts DC into the controller, and then charge a 12 volt battery. I will hook this up at my house to a solar system and 48 volt battery. Then run a ductless heat pump on 120 volts, with zero power from the grid! On another fifth wheel, I wired the panels for 24 volts, then connected to a 30 amp MPPT controller, that charges his 12 volt battery fine, with the maximum possible amperage to the battery, and the least amount of voltage loss due to the higher than normal voltage incoming from the solar panels. His solar prep system included a pair of #8 wires to the roof. I had to cut a hole into the roof, to find the wires, and then put a raintight outlet over the hole I created, then put one of the 4 solar panels over the top of that box, so no rain will ever hit that box!

Well documented and great price. One question though, you installed the 300watt, but I noticed on the price sheet the second panel for 1/2 the wattage was the same cost as your 300watt. Is there a quality or performance difference that drives up the cost?

What model do you have and what year? I have a 2019 3120RL and it is my 2nd Montana the old one was a 2015 HC and I hated the cable slides so I upgraded the hydridic. I like the Montana but I have had issues and no every time I take it on long trips I can enjoy it because I worry about Frame Flex I changed the Kingpin to a Lippert air ride to help the flexing I have a hard time believing Keystone would have not seen that in the build and engineering. Before I retired I was a manufacturing Engineer for heavy Oil Well Drilling equipment and I was a structural engineer and it doesn't take a skilled engineer to realize there would be a problem with the roads these days and the hitch weight.

How is your solar system still working out for you? Is that panel still working good for you?
