These are infinitely better than expensive grid tie arrays. Easy install just plug and play. Ive actually got 700 watts up in series-parallel. My roof pitch faces east and west so I have 3 to catch the morning sun and 4 to catch the afternoon sun. Working great the voltage is about maxed out around noon in the summer but I think the mppt keeps it low enough. Got it hooked up to a 400ah battery. Powers a 6000btu window ac all day or a 500 watt space heater for several hours a day in winter. Also have a charging station and wifi it runs. Electric bill is $100 less per month. The mppt is really great. It will charge even on the cloudiest days. Very handy during 2 power outages already. For the money the value is unbeatable.

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.

Installed on a trailer roof to keep battery charged and inverter working. Works great but solar panels aren’t great quality but do work fine. Just very light

The media could not be loaded. 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 😂

They have saved us so much, we use them every time we go to our land and they charge our rv... we have had them for 5 years now and we only had to fix one wire connector to one pannle when we pulled it a little to far when moving them. Great product, id buy again.
