400 Watt 12 Volt Premium Solar Panel Kit :4pcs 100W Solar Panel+ 40A MPPT Charge Controller+ Bluetooth Module+ Mounting Z Brackets, 400W 12V Solar Power Off Grid System for Home, RV, Boat.

Works exactly as it should! Im getting about 350 watts and 25.5 amps out of the controller at peak sunlight. The key is, at peak sunlight. If your angle is off or there's cloud cover it will drop dramatically, but that's just the nature of solar power. I went a little above and beyond and built a frame that is adjustable to maximize sunlight given the time of year. It helps to have a little electrical knowledge, but if you follow the instructions and know how to use the internet it should be a breeze to install. All hardware and wiring is included. The wiring is just enough to get you going so if you plan on having long runs plan to get some larger gauge wire. The kit came neatly packaged with clear instructions. The controller recognized my lifepo4 batteries and the parameters were good with me so I let it be, however, if youre looking for "out of the box plug and play" this isnt it. You dont have to be an engineer, but its good to have some building and electrical knowledge. I haven't tested the "load" yet, and dont plan on using it, but its charging my batteries just fine and my inverter is working like it should. The app is ok and the BT controller has a decent range. If youre looking for plug and play dont expect that from this kit. If youre ok with getting your hands dirty you'll have no issues getting it set up.

Worked excellent ! Really nice kit. Very satisfied

Really impressed with the output and efficiency of the panels and controller. Bought these to upgrade my solar setup from one 100W panel and 100ah of batteries to these with 450ah and the panels and controller and they have definitely exceeded my expectations. In full sun I'm getting over 400W to my batteries . The price is also fantastic, got them on a limited time deal for $330 but even at full price they're completely worth it!

I installed this system adding the four pannels with the two I already had. These pannels produced about the same power as the other ones I had, so that was good. The charge controller seemed to get pretty hot, even though I was nowhere near the limits of it. The load function did not work consistently. The Bluetooth module did not come with any useful instructions, so I had to rely on contacting EW through Amazon to get that resolved. There app did not work and had to use a 3rd party one. I did not use the wire, but the brackets worked well.

Its been working very good.. it can recharge a 12v 100 ah battery in 3 hours and keeps its self charged enough to run a a 10.1 cubic foot fridge. Very happy with this purchase.

Ordered this kit for my 27 fifth wheel and it has everything you need to hook it up. I got a disconnect switch and longer wire for the panel to disconnect switch. Shipping was faster than expected. Should have been here on a Friday and I got it Thursday instead. Would purchase again if needed.

Looks like I got the defective one. The controller will not charge. All parameters are within range and all start up procedures were followed properly but still no charge current. Internal fuses are still intact. The wire terminals are a good design but poor materials are used. The PV+ terminal broke due to low quality material. I had to find an alternate solution to connect to terminal which is more than a pain in the neck. The controller has a nice look to it but it’s worthless as of now. Customer support has not picked up the phone or returned my phone call. If you are new to solar and are buying this kit I recommend you just do your homework and build a system piece by piece with quality products. I have used ecoworthy panels in the past and they work but like the controller the panels are made of low quality thin aluminum. Please save yourself the time and headache and build a system on your own. Go with Outback or midnight solar for your charge controller. This kit is a waste of time and will only cause you to regret your purchase later. Do it right, do it yourself.

Works well on my R, v, happy.

I purchased this ECO-WORTHY 200-watt solar panel kit to expand our existing solar array at the cottage, and it has performed exceptionally well. The setup was straightforward, with all components fitting seamlessly into our existing 12-volt system. The connectors and wiring were clearly labelled, making it easy to tie in without extra tools or modifications. The panels have been consistent and dependable, providing strong, steady output even on overcast days. The construction feels solid, with sturdy framing and weather-resistant materials that have handled a full season outdoors without any issues. The included controller works as expected and keeps the charging levels stable. This kit is a great option for anyone looking to add capacity to a cottage, RV, or off-grid setup. It delivers reliable performance and excellent value, especially for those who want a hassle-free installation and dependable energy production.

Installed last fall on my rv. It drains more battery than it can charge. It shows 12.8 volts charge in full sun. 2 hours after sunset my brand new batteries are discharged. [Update] The batteries were drained by a short circut in trailer wiring. The system is working fine, however i upgraded the charge controller to mppt which is more efficient than original pwm.

So far it's good. I did some testing before setting it up how I want. I hooked it to my battery pack and when the sun was up a little but shadowed from trees in the distance I was averaging about 40 watts from 200 watts of panel. When the sun got over the trees I've been averaging about 160 watts. I just built a few legs to hold it up, if I play with the angle I can increase or decrease a bit so it's not at all a perfectly set up. My goal was use my battery pack for camping and my CPAP and other small devices. As long as I have sun it looks these panels will have no issue recharging the pack in about 4 hours from half. This is my first solar project and I think I have a few more ideas and might need to buy more! I haven't used the controller or long wires yet but I'm sure they will work. I'm looking forward to seeing how many watts in the summer when the sun is stronger.

These panels are great. Assembly was sumple and they perform exactly as described.

These work well for what they are.I don't give out a lot of five stare.Reviews.
