RENOGY Premium Solar Panel Kit 300W Polycrystalline Off Grid: 3pc 100W Poly solar panel UL Listed+ 40A MPPT Charge Controller+ MC4 20ft Adapter Kit+ Mounting Z Brackets

I originally bought the 100 watts panel kit that came with a PWM 30a charge controller, which is an OK system, . But it could not fully charge my Vmax 125ah battery with a 8-9 hours of full sun. So I purchased this system, it came with a nice BIG charge controller with heat sink. I currently have four 100 watts panel in parallel and within 2 hours, it was able to fully charged my 125ah battery. I am planning on getting another battery since the panels/charger can easily charge my battery. My setup also include a 1500 watts Tiger Claw which I also like. One thing I like to see included in the package are the MC4 Y connectors so I would not have to spend extra for those. Overall, I am very happy with this package.

preformed as expected, I was happy with the quality, price was reasonable although not a "super" deal, delivery was as stated, and I would purchase from the seller again.

I am still trying to figure out how to heat a green house during tge day and still have enough energy to heat at night. Things will get worse as winter sets in. Tech support is great but in a different time zone.

Nice system installed on my 5th wheel seems to be working great. Received the controller and it was damaged, contacted the company and received excellent service. Called customer service they were very helpful .Would have liked to had all the parts included branch connectors and MC4 connectors .

could use male a female connections.

I put this kit on my fifth wheel trailer and so far I have been on 3 trips and has work very well. I wish they would give you the adapters to run the solar in parralell not just series. They only let you run in series with the cables provided.
