1800 watts, that's 18, 100 watt panels, even the top of the semi truck enclosed trail doesn't have enough room for all that! It's a massive amount of cables and worrying even if you're using 200 watt panels. I boondock in AZ and there is a guy I see every winter in the desert and has about 4000 watts and he's pulling a 24 foot trailer behind with solar panels on both sides and on top that fold out the batteries are stuffed in between the solar panels I think he's running a 96 volt system. There's probably a half a million people in South Arizona boondocking in the winter time so it's much different than your situation, we have plenty of qrm from Neighbors!!! I'm only running about 300 watts of solar and in the winter time in AZ or in the mountains in the summer I rarely use my generator. It's a lot easier getting a 30 amp controller to be quiet then it is such a large system using 1800 watts of panel, what are you trying to do run your air conditioners?
