400 Watt 12 Volt Premium 4 Pcs 100W Panel+40A MPPT Charge Controller+ Bluetooth Module Fuse+ Mounting Z Brackets+Adaptor Kit +Tray Cables Set, 400W, Grid 12V Solar Power System

Great system, after 3 yrs no problems whatsoever. Keeps me charged up. Perfect for a simple off grid application for a decent value.

Renogy, the name in serious solar! Renogy was my gateway into hobby solar. I started with this 400 watt kit as an entry level, but it seriously was more than I expected. My batteries charge quickly and are very happy. It's currently deployed in a garden shed for tool battery charging and for exterior lights. Installation was easy. Setup was a breeze. The app leaves a little more to be desired but it's informative and easy to use. The built in functionality will keep you engaged. With little sun exposure on cloudy days, these small panels are rocking and still providing enough amps to keep the batteries happy. The cables included in this kit are of high quality. Mounting the controller was easy. The kit came with temp sensor and Bluetooth module which is great. When the panels are completely exposed to the sun, I taken my batteries from nearly dead to full charge in a few hours while using them for gardening. If you're looking for a hobby system for home use, a small system for off-grid applications, look no further! This is your last stop.

I bought and installed the Renogy 400 watt kit with the 40amp MPPT controller to install on a campervan in summer 2020. It’s Oct 2025 and it’s still going strong with no issues. Great starter kit for people new to solar and electronics. I’m hooked up to a couple of lithium deep cycle batteries. For winter/cloudy days I installed a dc to dc charger and get power from the alternator when driving. Between these two I have more power than I could ever use.

This has been a great learning journey for me. In my video, I had just set my circuitry up and wanted to run a test to see if it would power my Gaming PC and it works flawlessly. During the day(on the weekends) I can game and depending on the game I'm playing, it can stay topped off at 100% battery charge and only drains about 5 amps at most while the sun's out. My PC normally is around 180 watts and on higher end games draws around 480 watts nearly 20 amps so at night I make sure to only game about 2 to 3 hours before my 200Ah battery gets near 50%. I got my wife using it now and she's become energy cognizant making sure to even remind me to use our solar power system that we setup together. We love it and this is one of my favorite purchases that I've ever made of all time! I got the whole kit during a sale and it was totally worth it. I highly recommend anyone interested in solar to go this route. I accidentally drained my battery to 77A and the solar panels charged it back to 200A in 8 hours and that was with clouds. Usually on a full sunny day you'll be able to run lots of appliances if you get the 2000 watt inverter. We've run a 10A vacuum cleaner with ease, our magic bullet blender, my 10A Bluetooth Aura 3 bass speaker, my work laptop 50-150 watts, Keurig 1500 watts (good for 2 cups only draws a lot of power) , we've charged our rechargeable batteries, our phones , USB lights,etc... The point being this is the best for a beginner like me. It was not super hard to setup. Make sure you get a battery shunt to better monitor your battery. That was why I ended up draining down to 77amps. The Bluetooth feature is nice but as you'll see if you use only that it is totally unreliable for a battery monitor. Either way the best part about it, is you learn so much and gain new skills. Highly recommend this product! I've officially gone solar off grid for my basic appliance needs! Also exuse my cables running everywhere on the floor it was a temporary setup to test what I was trying to do. Excuse the mess in general 😂

I've purchased Renogy products for other applications. Given the overall quality, it's time to do it again. The kit was pretty much as expected. It does the job and works well. I have a few things to criticize: 1) The wiring from the panels to the controller is a bit short. I installed this system on a class A motorhome. The wiring from the roof, down the rear cap, into the electrical box just barely reached. Another meter would be just fine. 2) The 30 amp fuse block is a bit big and clunky. It was hard to find a place to mount it so that all the wiring worked out. 3) There was an extra 10 amp fuse included with panel style connectors on it. Had no idea where to put it as it is underrated for the combined output of the panels. 4) No instructions! Good thing I'm an electrical engineer and know what to do with this stuff. Only the controller had instructions of any kind. 5) The BT-1 remote monitor accessory is a joke. It can't be paired correctly, and takes a long time to get connected and display anything. All I want to do is see what the battery level is and how much current is being pushed. A simpler hardwired panel would be much better and faster to use. Overall, a good value. I'd recommend this to others.

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.

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.
