    This is an excellent solar system. I’ve installed 2 in separate off-grid systems. Both the shop and my cabin were designed for solar and these kits supply all the power I need for lights and a few tools.

    We purchased this for our overland rig 19 months ago. It is one of the best investments we have made. We do feel the cable should be upgraded to 4 or 6 gage to increase efficiency. We have not needed to plug our vehicle in since this was installed. With two 90 Ah deep cycle batteries we power the water pump, LED interior lights, twin compressor Luna fridge, a 52qt ARB fridge, and charge phones. During overcast and rainy days we bring in double the energy required to run the fridges. I was worried about the roof mount set up on our Northstar popup truck camper, but it works fine. We can feel the weight on the manual crack up roof, but there hasn’t been a problem. We did install a wind deflector to ease our minds at highway speeds but after 20k miles there has been no issue. I periodically inspect the attachment points and they are secure and sealed. We used the grey putty tape and as a precaution to keep the screws from coming loose we used the LocTite adhesive sealant on the screw threads. It seems to have locked them in place with zero issues. We spend time off road twisting around and over rough roads along with some severe high wind areas to include side winds. The only issue has been our wind deflector has flexed a bit but absolutely no issues with the panels, wires, connectors or mounts. Great product as we approach year two and are looking for options to use on a cabin.

    Easy to assemble. Printed wiring diagram from online. Used at our summer cabin. Put it together in an afternoon.

    We hired someone to install on our toyhauler. So far they work great.

    After a few anxious moments, and two calls to support, all works better than expected. I had switched polarity at the controller, which caused toe controller to indicate there was no input from the panels. It would be helpful if this problem was mentioned in the troubleshooting list.My batteries were down to 40% at sun-up when the panels began charging (4 panels). By noon,the batteries were fully charged.. This was WAY faster than I expected. Our camp is in the shade, but there is one part of the roof that gets full sun for 70% of the day, if it’s not cloudy. We will be adding more panels and batteries as we add more appliances. Right now it powers house lights, toaster, coffee maker and some power tools during the day. VERY happy.

    Outstanding system. I purchased this for my Class A RV. This is turnkey. Everything you need is included for easy installation. All manuals, directions and more are available online. Links given to easily print out what you need. The directions are straight forward, and very easy to understand. Not like some manuals with horrible translation.Everything was well packaged. UPS damaged the box but yet everything inside was intact.And the shipping time? Top notch. Quick. Professional.Look no further for a great solar kit.
