    I am just starting to hook it up and the system will work great for me. You do need to buy fuses and panel mounts to finish it off.

    Installed in a 2008 29’ Winnie Class-C We’ve been using our Windy Nation 400 Watt system all summer now and I have been putting off doing the review until I got a chance to do some real hands on testing of the system. I cannot believe how well this system works, although we made one upgrade to the Kit as it is sold (Upgraded the 1500Watt inverter to a 3K Watt) and added the remote on/off switch for the Solar and a control switch to seamlessly switch the power from Genny to Land and Solar W/O leaving the camper. The system has easily handled the load of our microwave, Refer and waterpump without even showing any signs of stress. On the last leg of a recent 3 week trip we took we spent a week off grid and we had full use of the 120V outlets for our computers, TV and coffee maker along with the other items mentioned. The only time the use of our Genny was necessary was to run the AC in the evening to cool her down. Although I could surely have installed the Kit myself I opted to have it done by a Pro (Cost me about $900 installation and I built the battery box myself) as I did not have the time or location to do the work before camping season started (I bought the kit 2/17/2016) Great job to Windy Nation for such a wonderful product and Kudos to Troy at Saint Louis RV in O’Fallon, MO […] for getting my installation done on time and on budget.

    Total Scam! Junk

    I love Windy Nation! The panels are durable and put out 17V-20V per day in good sunny weather. They’ve held out through some heavy storms and snow on my cargo Van. I was able to fit all 4 panels on the front 2/3rds of the vehicle by offsetting them slightly, 2 on each side. Leaves the perfect amount of space for 2 more if I ever want to upgrade!I was a complete beginner to solar panels, and I can’t say that it was easy to figure out. Honestly, there is not a single solar set up out there that will be easy for beginners, so dive in and embrace the learning curve. The cables attached to the panels were just long enough to be able to connect all 4 together in a 2×2 pattern. I do wish there had been slightly more of the 12 AWG wire, but it was barely long enough for my needs. In the future I’ll probably upgrade to 10 AWG or 8 AWG wire because I lose about 2V from the panel to the charge controller. A larger wire would help improve efficiency in this case.The inverter is pretty standard. It’s a step inverter, so you cannot use high power items like microwaves (for a microwave you need a pure sine wave inverter over 1500 watts). It’s perfect for my laptop, charging my cell phone, and using my flat iron.I have a 12 V DC Fridge/Freezer Dometic that is hooked up 24/7 and this system does really well for that. It can go a full 2 days after a full charge. So I don’t worry about occasional overcast weather. In the wintertime it can be a struggle when there is sometimes a week or two without sun. It will still bring in a charge, but not enough to charge the battery. On these days I charge my phone during the daytime and turn off my fridge at night when nothing is coming in. My panels are fixed on the roof, and I figure if I could tilt them they’d probably do a lot better during low sun. Occasionally they’ll even pick up .1V if I’m under a streetlamp at night.Recently my PWM Controller went on the fritz! It jumped sporadically between 10V to 19V and stopped charging my battery. I checked all connections with a Multimeter. Everything checked out and the only possibility was a faulty Controller. I contacted Windy Nation and went over my process of elimination and they are sending me a replacement! Their customer service was super fast and accommodated my change of address. (Keep up the good work guys!!)Some notes with the installation: You will need to buy your own mounting screws. I’d suggest some self tapping screws + 2 through the sides of each mount so that you have 2 screws per mount. 1 screw per mount may not be enough. Also, get some dicor to seal all your mounts as well as extra 4 AWG cables if you have more than 1 battery. You may also want to consider a fuse panel where you can directly wire your 12v appliances. You will need a bunch of butt splice connectors, some O ring or U ring connectors, a 30 amp fuse and an in-line fuse holder between the panels and controller.This install was not easy, for sure, and I had a lot of help. But the product is durable and the service from Windy Nation is awesome. Eventually I plan to upgrade my controller to an MPPT, and if you can find a kit that has one as well as an inverter, go for that. But for the cheaper option, I’m super satisfied with my solar setup.

    Completely powers our 5th wheel camper/ constuction camp. I have four 6v in a series parallel circut and unless we have a three or four day HEAVY cloud cover we have no problems with power. Powers our flat screen, dvd and suround sound and vacume every night. Power tools, batt chargers, water pumps, automotive batt charger, hair dryer, fans. Its like we are plugged into shore power.

    This is my review of the WindyNation complete 400W solar panel kit. I purchased the full kit with inverter and 400ah batteries. My plan for this kit was to use this for short term power outages to run a few circuits in our house. The kit arrived quickly and most was packaged very well. I think they should consider using heavier boxes for the batteries as the 4 I received were pretty banged up by the time I received them. I ended up not using the mounting brackets that came with the kit and ended up mounting mine on 2 – 10’ pieces of unistrut which are then bolted to a hinged angle iron mount I fabricated. I decided to ground mount the panels for easy access and wanted the ability to put them in a vertical position when I mow and when we have storms in the area with hail.Wiring the kit was pretty straight forward. I did have to purchase a ANL-250 fuse and holder to put in line with the inverter feed and 2 – 40 amp inline fuses for the panel input and battery output of the charge controller. I also decided to add a 300 amp battery disconnect switch inline with the inverter feed as well. I wired the output of the inverter to a manual transfer switch that I built that switches both hots and neutrals on 4 separate circuits in the house.I did have a few questions and WindyNation was quick to respond to each of my email inquiries.The supplied inverter worked great with the refrigerator, microwave and lights, tv, etc. The only problem I had was that 2 UPS’s that I own did not like the modified sine wave from the supplied inverter and refused to switch back to utility power when powered from the inverter. I went ahead and purchased a pure sine wave inverter and that solved the issues with the UPS’s. I will keep the supplied inverter as a spare/backup.I am very happy with the system so far. The panels seem to be working well and even put out more power than I expected on overcast days. I would highly recommend this kit if you are thinking about a solar panel kit.Update: Rewired my panels from a 12V to 24V configuration which eliminated quite a few connections and swapped out the charge controller with a MPPT controller that has remote monitoring capabilities. On decent days now seeings watt output of the panels peaking in the 360 watt range. Just ordered 4 more panels too add to my system.

    This kit is my savior, hurricane stricken, this taking the load of the essentials

  9. Stephen

    Easy installation and has worked perfectly….just make sure you buy the 30 AMP fuses for both the batteries and the solar array.

  10. Amazon Customer

    Great product. Wish I’d known there was an option for a pure sine wave inverter.The modified sine wave inverter Won’t Work with digital devices suck as microwave, computer, tv and such.Now I’m having to swap the inverter with Windynation.
