10 reviews for Renogy 400 Watt 12 Volt Monocrystalline Solar Starter Kit with Wanderer 

  1. RyanKarla

    These are a great solution if you have an off-grid project and you’re not a solar electrical engineer! They’re plug-and-play. They come with all the wiring and mounting brackets to get the panels mounted and get them connected to the charge controller (also included). The instructions in the box are very basic, but Renogy has a YouTube channel with video demonstrations of how to install, so it’s very easy. The hardest part is figuring out how to run the wires through your camper/van/cabin/whatever. This is a fantastic all-in-one kit and Renogy is a great company.

    I like the Renogy 12V dolor systems. I put a 200 watt system on my old motorhome. I put a 400 watt system on the newer motorhome. We put a 200 watt system on my sons camping trailer. Preparing to install a 200 watt system on my grandsons camping trailer and a 400 watt system on another sons motorhome. With these dolor systems we forget about battery issues. The solar systems work very well keeping the batteries charged. Read up on the renogy controllers. They are amazing. The deep cycle batteries last much longer with these systems also. I highly recommend these Renogy systems.

    I’m loving my solar panels by Renogy. I am making enough power to run my Koi pond at night saving some real money. They and great quality and installation was straight forward. Very satisfied.#AdventureUninterrupted@renogy

    When I got my first Renogy 400 watt Solar Kit from Amazon, a few months ago, i was impressed with the quality solar kit. The panels are sleek and i like the data on the back panel. The MPPT/40 Amp, is the brain of the unit. Hook up your battery cables first to it, then your solar panels, and watch it collect solar Photons! Amazing and how exciting. In fact, they are so beautiful and rugged, I got several of these 400 watt kits and one Renogy 800 watt solar kit. I just recently got my April electrical bill and my KW usage was reduced to 52%. I only had 800 watts then. Now i think i have 2.6 KW solar power! All thanks to Amazon and Renogy!! I recently bought 2 x 500 watt wind generators from yes, Amazon at a great price. Now i have an interesting Hybrid Wind-Solar System. I’m trying to reduce my carbon footprint and be the custodian of Earth! Go Green!

    Unbelievable easy to install! The only hard thing was deciding where to run my wires so they would be out of sight and have the least chance for water leakage. Once that was decided, it was a piece of cake. The only negative is that the kit should have included a 4 way connector to connect all the panels fuses from panels to the controller and the controller to the battery. I’m producing over 15 amps of power with full sunlight and recharging my 2 house batteries in my motorhome in very little time….about an hour when starting at 35%. I also added the bluetooth module which is pretty cool to be able to check everything with the app.

    I’ve purchased two of these 400W kits and one 200W kit to use for emergency power during hurricane season. As I live in a condo I cannot use a generator during power outages for safety reasons.As someone who has worked for a small business building and installing solar powered roof ventilator fans I recognized the quality of Renogy was good by looking at the product. I expect a lifetime of service from these panels.The panels are normally stored, but I expect that they would have no problem meeting their 25yr lifetime with ease on a Florida roof.I have used the panels in an 800w array with a Morningstar ProStar MPPT controller to charge a 300A 12v battery array PERFECTLY!The power system was for amateur radio’s ARRL Field Day 2018. The system powered three 100W radios for a 24 hour simulated emergency with ease. The radios when transmitting draw up to about 350W each and 50W-60W each during recieving.Under difficult cloud conditions I was able to bank power.These are not state of the art panels so they are a bit bigger using standard monocrystaline design. But, as I say, “If you have the room buy regular panels cheaper and your payback time is quicker.”If you have very limited space and a large budget then knock yourself out paying 2X-4X for THE SAME POWER in a SLIGHTLY SMALLER package.If you have room I would do a ground based PV array instead of a roof mounted array in order to make maintenance easier and cheaper on both the roof and PV array.Buy Renogy panels and it hard to go wrong.My panels are attached in pairs with 36” stainless steal piano hinges for portable operations.

    Using these with a 4 100AH AGM batteries in a self converted RV/campervan. Have them setup with parallel connectors which you will have to buy separately.Works excellent, keeps the batteries topped off. Ussually run a diesel heater, roof vent, 12v fridge, LED lights, charging devices, and have a 1500w inverter.Setup and wiring is mad easy, but make sure to fuse it between the panels and controller.Going to need the watertight drop box to bring the wires inside from the roof.Highly recommend a 12v battery shunt/meter for a better view on your batteries power status; as the battery % meter on the solar controller is pretty useless. Ussually leave the controller on the daily Amps created view, and watch battery status on the shunt meter.Overall really happy with it, nothing but reliable, and has not left me needing more power. Heck, ussually pulling in an amp or so even on cloudy/rainy days. Can make it 2-3 days without any sun before I need to charge the batteries with my engine.The indicator lights can be useful, but they are too bright so I covered them in electrical tape.

    I have purchased the 400W monocrystalline kit. It comes with the 30amp Wanderer (CTRL-WND30) charge controller. The provided literature states it has 4 charging modes; Bulk charge, Boost charge, Float charge and Equalization.The manual states that Equalization:“Is carried out every 28 days of the month. It is intentional overcharging of the battery for a controlled period of time. Certain types of batteries benefit from the periodic equalizing charge, which can stir the electrolyte, balance battery voltage and complete chemical reaction. Equalizing charge increases the battery voltage, higher than the standard voltage, which gasifies the battery electrolyte. WARNING: Once equalization is active in the battery charging, it will not exit this stage unless there is adequate charging current from the solar panel. There should be NO load on the batteries when in the equalization charging stage…”How does the charger determine the 28th day?What certain types of batteries benefit from equalization?If the charging current should fall during equalization will the device resume this mode when it (charging current) is adequate?What is the definition of adequate charging current?What are the consequences of a battery load if the unit enters the equalization process? If for example I had a continuous load on the system to for example, keep a small mini refrigerator running (via a DC to AC inverter) will this be of consequence to the solar system, charger or appliance?I see quite a bit of ambiguity in reference to the Equalization mode as evidenced by lack of defining the terms and parameters in the manual…The Boost charging mode states that:“When the battery has charged to the Boost voltage set point, it undergoes an absorption stage which is equivalent to constant voltage regulation to prevent heating and excessive gassing in the battery. The default time for this is 120 minutes but it can be customizable as needed.”How does one customize the default Boost time? No reference or instruction is given for this.I had ordered the 400W kit from Amazon. What was delivered from Renogy solar via FedEx was 3 panels and kit accessories, that is, 300 watt kit. I contacted Amazon customer support and they quickly set it right and had another entire complete 400W kit delivered. I have to make arrangements for the pickup of the entirety of the 300W kit and components. +1 for Amazon for quick no B.S. customer service. -1 for Renogy for not being able to count to 4.Update: I had contacted Amazon customer service on the issue they immediately made a fix for it by sending me a new kit with for solar panels and I had a few questions on the charge controller technical specs sent to renogy tech support I upgraded my review to 5 stars for the really quick fast customer service on both ends Amazon took care of me and got my order shipped proper to me and Renegy responded within the day on my customer service questions to my satisfaction so plus one for all of them for taking care of business and very happy and satisfied with my purchase… thanks!

    I now have a total of 10 of these panels. On sunny days it will fully charge my 1600ah battery bank by 11:00. When it’s cloudy, it still does a good job with charging.Update: I added an additional 12 panels (total 2200 watts), converted to 2- 24 vdc systems with a total of 16- golf cart batteries (8 each system), installed 2- Aims pure sine wave inverters connected to my home breaker box. I now have enough power to run my house. I can even run a window air conditioner on sunny days. …and, no power company!Update: I installed a 400 watt system to power my well.Update: I added an additional 400 watts to the system on my house. I now have a total of 2600 watts for my house and 400 watts for my well. At this time I don’t see the need for any additional panels. What I need now is more batteries.

    This is the second kit I bought from Renogy and here on Amazon. You can’t beat the value for the money. Easy to set up. As long as you watch a bunch of videos. The only complaint would be if you want to run this four panel system in a line across, or up and down, you have to buy extension cables. (sold separately) But of course you do.If you want to hook them up in a big square, no problem. Ready to go right out of the box. I tried to call tech support about it but just can’t get through. I get it, it costs money to answer stupid questions.I have found that Renogy is sending out good quality and quickly. Where they are missing the boat, in my opinion, is that the kits are so good that frankly every home should have one for emergency power. And more. Would we pay a little bit more so that the cables we need are in the box? Of Course we would. Would we pay a little more to have someone at the other end of a phone for newbies trying to hook things up? Of course.The easier and more user friendly all this solar stuff is just makes more people buy them. I can’t tell you how many people stop by asking my my system. Always the same questions. I try and explain it and they mostly just walk away thinking its all so confusing. It isn’t. About the time I mention what you need isn’t in the kit box, you know ….ext cables, adaptors, inverters….they just start rolling their eyes.Don’t get me wrong, If I bought a little off grid cabin I would buy a big 8 panel kit in a heartbeat from Renogy, wouldn’t even look at another company. But….and here is the big but……should I really have to spend all day trying to find videos on how to hook it all up? Would I pay a little more to have maybe a piece of paper showing me what to hook up where on the panels going this way or that? Would I like all the cables included in the kit that I might use in different configurations? I think you know the answer and I bet you would too.
