I've wanted to go solar with my rv for several years. I've gotten estimates, gone back and forth over what I needed, etc. My rv is small, but my goal was big - to hopefully not ever need my generator. Well, with this system and adding a 2nd solar panel (and 3 more aux batteries) I've done it. I actually had my generator taken out and this system installed. Because I removed the generator, the system was installed through it's connections and I didn't need the controller included. Made installation a tad easier. It's only been a week, but I've been using solar only - and only had one sunny day. The overcast/cloudy days have still recharged the batteries (and I've needed to run my heat every night) and during the sunny day I put things to a test - vacuuming, etc - and it kept up with me.
I can run my microwave, but that's really pulling the charges - so don't intend to while boondocking (I never used the ac when boondocking before, so that's not a loss). I also added another 12 volt connection off the inverter to allow me to do some things (like charge my phone/computer/camera batteries, etc) without pulling as much as the inverter does. Used that every day it was cloudy.
I'm very impressed and wish I'd done this a couple years ago. Better late than never!
Things to consider - the 1500 watt inverter included is strong - if you only have 1 or 2 batteries, you'll need to add a couple if you want to take advantage of this. You'd be able to drain 1 or 2 batteries quickly if you used the power the inverter provides. I went to 4 batteries, and have room for 2 more if wanted. The controller, since I didn't install it, I can't comment on. I also didn't install the remote - as my rig is so small that there is no need for it.
This is still so new to me - will update if things change/occur that should be mentioned.
