  • Very easy to install
Size: 400W + 40A MPPT
Received our kit yesterday, very well packaged it came. Put it together today in about 2 and a half hours on my RV roof. Followed the directions that came with the controller, then put the brackets on the panels, put those up on the roof and screwed them down, I put a little caulk under each bracket. Then hooked up the wires as shown in the diagram above. Put those into a junction box and then into the RV and hooking them into the controller, went back up on the roof and took the cardboard off the panels, started working instantly. This was really easy for me to put together, if I could suggest something to the company... It would be to offer different packages of wire length cuz I'm sure not everyone could get by like I did. ... show more
