This is a great kit. It comes with almost everything you need. Fuses, wiring, controller, mounts, panels and all the bolts and screws you need. I had to buy a solar array disconnect switch separately. The system took me about 6 hours to install. Most of that time was spent fishing wires through my camper walls. I wired the panels in 2 series, 2 parallel. Once hooked up I put my camper in a sunny area and was getting 260 watts, will work even better in full sun. Not bad given there was some small shaded areas on the panels and they are laying flat. Don't expect to get 400 watts unless your panels are directly facing full sun. That is how solar works. I bought the BL1 Bluetooth as well and it is awesome for monitoring the system which I have hidden out of sight. I can camp anywhere for any amount of time now with no shortage of power. Great value for the money. There are no instructions. If you don't know what you are doing, pay someone who does or educate yourself accordingly.

This setup is the perfect kit to add a decent amount of solar to a motorhome to support 12v operation. It comes with everything you need (the panels get hooked up in series (+-+-+-+-) and the cables are all sized accordingly. I have been 'logging on' to the renogy app on my phone to monitor my production and consumption. Ive been very pleased with my findings. These mppt controllers are way nicer than that cheap h+rb+or freight one I started out with. Because they are wired in series the mppt controller always has enough volts to give the batteries the level they need. Sometimes it holds them at 13.7, sometimes it goes into boost mode to give them a good charge... I know just enough to be dangerous about solar, and I had no problem hooking it up or using it. If you have a screwdriver, wrench, and a drill, you can install this. Only thing you may need is a good sealant if you go thru the roof with the two solar wires.Don't waste your money on those cheap kits with the cheap controllers. Invest in a product that will do what you want it to do, not fall short of your expectations time and time again. Highly recommend this Renogy 400w mppt solar kit. You can't beat it for the price!!!

Arrived in record time, 2 days, awesome! Unfortunately one panel was shattered and I had to send it back. Would i purchase again? Yes! I figure eventually I'll get one with all the pieces intact.

I had researched solar builds and decided my shed would be a good proof of concept to later do a full build on my house. Its a standard 28x70 ranch. The shed was 10x12. I bought the Renogy kit after reviewing the Eco product and similar others. The equipment arrived promptly and I was quite fortunate as no parts were broke in shipment. Renogy's kit takes out all of the guess work. It had 4 x 100w Solar Panels, the 40a MPTT charge controller and the cabling as well as the bluetooth module. As well I followed "DIY Solar Power with Will Prowse". He will teach you everything you ever wanted to know about setup of solar, ad nausem :-) As you can see I added in a ANL bus bars. The batteries were 2 x 12v 50a LiPOFe. They are a bit pricey but allow a drain as low as 5-10%. That alone is worth the money.I use the power for the shed lights, and outlets. I can hold a 1/2 " corded drill on for a good 10mins at full spin using the Renogy 2000w inverter and it only degrades the batteries 20-30%. But that is not real work. I used my electric chain saw for 2-3 hours no worries. And my electric log splitter. During peak of day, the 4 x 100w panels keep the batteries full while I work. Not even sure it degrades much. I did drain the batteries one time by leaving all dc lights on and the 2000w inverter with a 12 inch electric fan running. But that was only once and proved that the system could recharge the batteries within 4 - 6 hours or less.The bluetooth modules maximizes the value. The Renogy DC Home app collects monthly data and provides realtime metrics for the system. I keep the inverter directly off the battery and not the charge controller. The load on the controller is only rated I couldn't be happier. I have been running successfully from late August '21 to present mid Dec '21. I do not anticipate issues.UPDATE:I am now at May '24 and the system still runs like a champ. I did upgrade my battery to a 2800wh LiFOe. I wanted to run wireless bridge from my house to a small switch and a small PC for a "remote" site. The power last a weekend without sun.Has proven a fine investment.
