Renogy 100W 12V Solar Panel Starter Kit with 30A PWM Controller

This is a top-shelf panel constructed with obvious pride, and is the second I've purchased via Amazon for battery charging on an RV. It is relatively light-weight, yet sturdy, and is ideal for the applications that I selected it for; mounting on the front of the RV on a piano-type hinge, supported by gas-assist struts when deployed. It is securely dogged-down for travel on rubber bumper "feet" mounted to the bottom edge, and can be raised and made fast to any angle up to about ten degrees above the horizontal for best exposure, depending upon where the rig is parked and the angle of the solar ecliptic.The mounting location on the front of the RV trailer is actually over the front window and window cover, but does not impede the operation of the window when the panel is deployed. I selected this installation method both for short cable proximity to the charge controller and my batteries, the convenience of mounting the charge controller under cover close to the batteries, and to permit the installation without additional roof penetrations for the mounting hardware. I have just completed the actual mount, and have not yet connected the module, but the first application has worked flawlessly, and the module's output was as advertised. I was able to purchase most of the associated hardware through Amazon, although this time I have opted for much lighter-weight capacity gas struts, as the 60# capacity struts were way over-kill. I utilized structural aluminum bar and tube stock for the hinge attachment carrying point, which I attached to the front of the trailer with robust screws and embedded in epoxy. It is possible that some similar applications would require actual through-bolting with a backing plate or equivalent reinforcement. The charge controller employs a nifty programmable load center, which will be useful for a motion-detector security light/porch light arrangement.This controller would be perfect if it incorporated a clear dust cover. The fact that Renogy has assembled a complete solar-electric charging module kit greatly simplifies the installation, and as mentioned at the outset of this comment, the quality of manufacturing is truly outstanding, and is very reasonable priced on a cost-per basis. Backed by Amazon's superb point-of-sale and delivery, I'm glad I chose Renogy for my first and second go-rounds, and I will certainly do so again! Davitt M. Armstrong

I am a RV Technician, and a good solar panel is the first thing I add to my personal RVs. Keeps the battery charged, and regardless of usage my battery(1 full one is all I need) is fully recharged by 2:00 the next day, I don't have to remove it during winter as charged batteries will not freeze. The benefits of battery health, and the need for fewer batteries are worth the cost of at least one solar panel. Mono-crystaline panels are well worth the cost, as amorphous panels loose their efficiency after a few years - google it. Mono-crystaline also work in well overcast and low light conditions, as well as performing better in a fixed mount setting. I got the 100 W kit with 30 Amp controller (plan to add more later) with the nice mounting brackets. Simple to install, with the caveat that you need to be smart enough to unscrew the leads before you try inserting and tightening the wires (I saw a review that slammed the quality of the controller because the wires would not screw down tight). I like the 20' of supplied wire (only needed about 8 on my RV, then 25' of 10/2 Romex from controller to battery). I get 15.4 V with sun direct overhead, and the controller knocks it down to 13.1 V to head towards the battery (I get < 0.1 V line loss in my configuration) Good price for the kit, and a well thought out contents. You need to supply the runs to battery and/or load, or use what is left from the 20' supplied. Brackets are super, as I have had to make my own in the past - not fun. Overall a great kit that I wish everyone had installed on an RV, especially those who call me and complain about $200 and up to replace batteries after a winter without removing or recharging them. Particularly important now with the 12 V slideouts - not fun if you dry camp and have to crank them in by hand (remove a lead to motor first, else they will backfeed the 12V system)

Renogy 100 Watts 12 Volts Monocrystalline Solar Starter Kit w/100W Solar Panel + 30A PWM Negative ground Charge Controller + MC4 Connectors +Tray Cable+ Mounting Z Brackets for RV, Boat I purchased this to install on the Roof of my Jeep wrangler (overland built) to serve as a way to charge an auxiliary deep cycle battery which powers my permanently mounted ARB fridge as well as all the camp LED lights and recharge phones and electronic equipment. I was fairly new at this solar thing but did a ton of research on the subject before settling on this. There are tons of off-brand products in this category as well as a vast array of pricing options, both higher and lower than this set up. However, after careful consideration and countless review reading and youtube watching, I decided that this set up was best suited for my application. The problem: I built my Jeep to do some overlanding and one thing that I cannot live with is my ARB fridge which is permanently mounted in the kitchen which sits in the back of the car. The car doesn't have a dual battery system and so the fridge is/was plugged into the cranking battery which is not optimal as you do run the risk of the fridge draining your cranking battery and leaving you stranded (NOTE: Fridge does have a shut off feature which measures the voltage of the battery and turn itself off if said voltage is below "x" volts. Also my Jeep is a standard so I can push it / get a quick tow to get it started and I do always have a battery pack / starter as a precaution...). The solution: Getting an auxiliary battery to supply the fridge (and other accessories) and a solar panel to keep this battery topped off while at camp and on the road. I chose Renogy after my many hours of research because of the name brand recognition and the the many reviews that seem to point at a great company with solid products and good support. So far I can say that the reviews are 100% correct in that I made the right choice. The package arrived well wrapped and precisely as advertised. The panel is solidly built and all the cabling provided is the correct gauge with the proper connectors. I really wanted to get a name brand Charge controller after reading that cheaply made units can both be highly inefficient and could be dangerous. In hindsight I probably would rather the version of the solar charge controller than has the integrated LED screen providing the charging and consumption metrics but price point on this project was met with the simpler unit. I am using some third party units to measure charging metrics and load usage which is fine but does require more wiring. The panel comes with all the brackets to install in on a flat surface and my guess is that 90% of the time people will need to do some custom installation of sort so these brackets, although perfectly adequate for a flat install are useless to me at the moment. All the connections are well made and this gives me no reason to believe that they will not last a long time. Right now in full sun and FLAT on my roof rack (note: flat is not optimal as the sun is never perfectly perpendicular to the panel and a 45 degree angle would be better to adjust for the that) the panel does produce about 5.5/6 AmpH and about 24 volts which according to what I calculated will be more than adequate to keep the smaller deep cycle (35amp hour) battery I am using topped off and run all the accessories I want to run off of it. I intent to post photos of the set up once it's complete as well as add to this review when i have had a chance to use the system to a greater extent.

I ordered this item in the middle of a pandemic where it was on back-order. Apparently I got one of the last ones because it arrived within 3 or 4 days when the Amazon site said it would be available in 30 days. So really happy to receive item quickly and it is a great value for a solar starter kit. I'm using it to power 1-12V deep-cycle batteries on a boat as sole power source. The item is as described and contains all parts, packaged well for shipping. The online and hard copy User's Guide/Installation instructions are well thought out and easy to understand. I was in a hurry to install and could have benefited studying the User's Guide, systematically, but didn't have the time as this is my main source of power. In buying a solar starter kit (from a different buyer on a different platform) I found that one needs to know the exact parts that are needed for individual needs (extension wiring for panel to reach controller 10'-20', and/or z brackets to secure panel in place). Different kits offer different items and leave out other important ones so it's important to check all the parts needed to install before buying and pay attention to the features (lcd screen, usb ports, etc) of the controller. There are also blue tooth units and a phone app to use to track what the panel is doing and the state of the batteries, for an additional charge. In this kit (100W mono panel, 30A controller), the panel works well and will charge 2-12V deep-cycle batteries linked together, at 50% charge level, in two days of direct sunlight to a full float charge. The panel arrived in good shape but I think needs mounted in a permanent location with a metal supporting stand rather than using in a temporary setting. The metal surrounding the panel crystals could be sturdier. The controller is plastic but mounts easily, works well, and is easy to install to the panel and on the wall. I think that this is a really good starter solar kit for those wanting to use and understand solar, for the price, in an off-grid system. I like that the company put the effort into writing a good installation manual and phone app for tracking. Materials used in manufacture could be a little stronger and sturdier in the panel. Tech support is very difficult to reach: the 800 number rings a fast busy signal (permanently), the local phone number in Southern Cal has long waits (27 callers ahead on several occasions), and it takes about 2 days to get an e-mail answer from tech support that gives cut and dried answers from the book and doesn't volunteer extra information. All in all, this purchase was a great value for a well-working product, but along with value be prepared to do a lot of the research/troubleshooting on your own. I hope that after the pandemic, Renogy becomes easier to reach for after sale and tech support.

Just received and installed today and so far it’s really well built, clear instructions, and started working right away. Would very much recommend. I bought a 100 W for my dump trailer battery and I know that may seem like overkill but that will be plenty of power to keep it good and hot for Junk Removal!

Was pricing our options for a client who'd requested off grid power for their rural sawmill. They needed enough power to run a small beer fridge and for smart phones and a very efficient little notebook. They have generators for running real equipment, and the saws use internal combustion engines. I had a small fridge lying about (actually have another 4 or so). Pick them up at estate sales and such for five to twenty bucks. Used a kWh measuring device (KillaWatt Brand) and ran it for a week, determining that it was consuming about 300 wH per day. So I figured a 100 W panel ought to be sufficient given that they have good sun resource on any day warm enough to need beer. Note that I did not calculate in the fact that they'd be putting extra stress on the fridge by putting warm six packs in it every day or so. Could have done this by factoring in the specific heat of water (how much energy it takes to raise a given mass of water a given degree) and then working backwards and assuming an inefficiency coefficient based on the efficiency of refrigeration processes. If I had done so and used an egregiously inefficient coeficient, say 1 Wh of cooling (i.e., BTU converted to watt hours) requiring 1 Wh of energy to run the fridge, I'd get about 80 Wh of energy consumption to cool a gallon of beer, or about 50 Wh for a 6 pack. Frankly, I should have included this in the estimation, but assumed it wouldn't be that big a deal. Note that a 1 to 1 ratio is fairly inefficient, so there's a lot of wiggle room here. So, bottom line is that even if they switch out a 6 pack a day, total consumption ought not to exceed about 350 - 400 Wh per day. The roof pitch and sun resource here (southern Oregon) is pretty good. I figured they'd get at least 600 Wh ,delivered, with this panel in this location, in the summer. Bottom line is that the panel seems to be providing enough energy, but we are going to need to add an additional 1200 wH battery since the depth of discharge gets too high if we get any morning fog. Even without that, 400 Wh is about a 33% DoD. That's not bad, but given the occasional morning fog issue, the battery takes some stress on occasion. For our application, and the price of an extra panel, it might not be a bad idea to add another panel as well. They don't drink a lot of beer in the winter, but it might not hurt. As for the system, it was very easy to install and came with mounting brackets and sufficient cable to do it all out of the box. The only problem was that the client initially used an old deep cycle battery, and on occasion the inverter was shutting down due to low voltage since it wasn't capable of storing 1200 Wh. I ran a new battery over and they installed it. I THINK but can't be sure, that they reversed the polarity or shorted the Charge Controller output leads. When I got there, the Charge Controller was not putting out any current. I had a small Victron MPPT unit in the truck so I just subbed it out. I haven't thoroughly investigated the dead unit yet, but noticed it's got two soldered in fuses(!) I will hook it up and jump the fuses one at a time to see if that's what happened (yes, shame on me, I should have put some fast blowing fuses in the wiring - will get back there in the next week or two to do that). Anyway, the client is happy and I can still go in there to buy lumber without a problem. Amazon has sent me a replacement Charge Controller, no questions asked, so that is good. I bought the Assurion Warranty on it. I do want to add that the Victron is overkill for this app so I am going to sub it out with the replacement. The reason is that one of the nicest things about this kit is that the charge controller, while only a PWM, IS rated for 30 amps. So it's easily expandable. (Upto 4 panels I believe.) That's a nice feature, and the Vicron can handle higher voltage, so it's wasted on this application. All in all I highly recommend this kit for small or introductory set ups. Perfect for small dedicated stand alone applications such as a Flojet Water Pump to slowly pump water up a hill to a cistern for gravity flow to an application, or small fridge. Just don't forget to add external fuses. For that matter, Renogy ought to bump the price up $10 and include them.

Bought the 100watt kitt for a 24 foot travel trailer I am in the process of remodeling. I have (2) 12V 27 inch deep cycle marine batteries I picked up at a hardware store for 80 bucks each. for a total of 220 amp hours when topped off. They are wired in parallell. The panel was the easiest part of the install. just use butyll tape on the bottom of the brakets, screw onto roof, and then cover everything in lap sealant. I ran the cables down one of my vent cover holes which luckly was almost directly above where I wanted to mount the panel. Running the cables and getting the electronics set up was the biggest challenge. I ended up mounting the charge controller and fuses for the system under my travel trailers kitchen sink. I used a 1 foot by 1 foot piece of plywood. I wired up and installed as many components on the board as I could before installling. This made it easier to not be assembling everything under the sink. The Campers electrical box housing the fuses and converter box are a few feet away from my where I mounted my chage contoller undert the sink. rather than run from the charge controller directly to the battery I went into the electrical box and joined with the 6 guage wires already going from the converter to the battery. This saved me alot of money on cable! I finished installing on a sunday night. The sun was down and so I couldnt test right away. I turned on half the lights in the camper, the power vent, and left my 24 inch TV running off an inverter. I let these appliances drain on my power bank all night. I turned everything off monday morning. I saw that the green light was blinking which indicated that it was charging. By the time I got home for lunch 4 hours later the batteries were topped off. It has been installed for a week now and the batteries have never gone below 70% full with full usage of the appliances. I also purchased a volt meter/usb charger/12v socket so I can measure the voltage and charge things, as you can see in one of the pictures. I am not an electrician. I know very little about electricity. I think this was a fairly easy project that turned out awesome. I am very happy with the Renogy proucts they seem durable and have lived up to the other great reviews I read. I would suggest this brand and prouct to anyone looking to try out solar power. I was very impressed!!! You should buy this for your camper you wont be disappointed.

been working great, easy install an keeps battery up on camper

no possible to have assistance .... all back

Sehr gut Plug and Play Gefällt mir. :-)

funciona bien pero no lo probe bien porque estuvo nublado y sacaba pocos w

Todo en orden
