Easy installation and works as intended.

I installed this 400 watt rated system two weeks ago. The panels are on the pilot house roof of my powerboat connected in series. I installed the supplied 10A fuse. The Rover MPPT charge controller is in the engine room. The system charges a 260 AH flooded lead acid battery bank. I also have a Renogy battery monitor.
The system is intended to allow full time operation of an undercounter refrigerator while the boat is on it’s mooring. The system is operating as intended. The battery monitor indicates 100% battery capacity by early afternoon even on fully overcast days.
I am very happy.

Wiring not correct

The panels and controler are 5 star but the wiring connectors and fuses do not work. Had to buy a 4 way connector and a 30 amp inline fuse to make it work.

Needs better instructions

The quality cannot be understated however as someone who's never worked with electronics and was under the assumption the instructions would be helpful in assisting the set up I was wrong. The instructions include everything you need to know about the control box but not a lick about proper instalation into the box or connecting your battery to the solar panels and the panels to eachother for the price I paid for a no doubt quality system I would like to see at least 5 more pages of instructions on how to connect everything and what everything should look like when put together and what to look for in improper instalation.

Great system

Fairly easy to install. Just got back from a 10 day hunting trip and I didn’t need to run the generator the whole time. So far a great product. The only complaint was all the wire leads are fairly short. It limits your options on how you position the panels on the roof. I also had to buy longer wire to run from the charge control to the battery. But over all The system works great and has been a good investment

I like your products but unfortunately it looks as if you guys no longer use bread pay financial as means of payment. I was looking forward to purchasing more of your products but because you no longer use bread pay I may not be able to.

Great Kit!!! Need option for longer wires

Verified Purchase:Yes
Such a great starter kit. Arrived perfect! Panels are doing great, actually pulled 415 watts on my rv yesterday with the panels angled at the correct degree to the south. Charge controller is awesome and all wires and hookups work great. Two things to note: the charge controller on the app will read out what the controller is converting at that moment for your batteries current needs. Can be confusing to think you’re only getting 2 amps when you have 79 volts and 200-300 watts - but it’s likely because your batteries are charged and it’s just sending all that is needed. Second, if you have a 5th wheel or longer trailer, the PV wires from the panels to the controller WILL NOT be long enough. I order 40ft and it was perfect. Prob about 6-8 ft left over. Wish that was an optional upgrade at checkout.

Great kit!! Everything you need.

I don't usually write reviews, but I figured I would in this case: The main reason I purchased this kit is because you can actually call Renogy, and they actually have someone to answer the phone who is eager to answer questions and assist in tech advise. To me, that's huge!
Anyways, I installed this 3 years ago for my off-grid tiny beach house in Mexico. It has functioned perfectly and is holding up great. The only maintenance I've performed is just cleaning the panels. This system is small, but perfect for a low voltage setup (like tiny home or RV) - my home is all 12v, with a small inverter for light AC needs.
The kit was easy to install, and came with everything I needed. I fabricated a simple rack for the panels (see pic). For batteries, and purchased 4 "VMAX" 6V (225Ah) AGM Deep Cycle Batteries from Amazon (connected them in series and parallel - see pic). I couldn't be happier with this system - Thanks Renogy.
