Review: Works like it should and met expectations - 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.
Review: Excellent kit - Worked excellent ! Really nice kit. Very satisfied

## Questions & Answers

**Q: Can these be laid down on our patio**
A: Why?  I laid these out in my driveway to test them.  Two panels in series, then those in parallel to the charge controller. Be sure to connect the battery first. Input voltage was 30v. My output was 23 amps at 12v.  
You can mount the panels flat, vertical, on a roof, or A frame bracket. Output varies with the orientation to the sun.  Be sure to leave an air gap under the panel. 
Again, I’m not sure what your question is referring to, but I hope this helps.

**Q: Screen is blank. how does the screen turn on? i connected the battery and have 12.6v but i just have a blank screen any assust would be appreciated.**
A: Connect both the battery and solar panels to the charge controller. Make sure that you have the positive and negative wires correct.

**Q: Why am i only getting  200 watts from 400 watts of panels? Clear sunshine all day**
A: The max watt for solar panels are only achieve with clear skies and solar panels that are tilted directly at the sun.

**Q: Is there any way to get any instructions for this kit? Mine did not come with any instructions.**
A: There are no instructions.  “Google” some of the different solar panel voltage configurations.  You could run all 4 in parallel for 12v and get higher amperage. Wiring all 4 in series gives 48v, lower amperage so you don’t need as big of wire.  I’m using 2 in series, then those in parallel resulting in 24 volts.  The charge controller will reduce that 24v to 12v towards the battery.  PAY ATTENTION  TO POLARITY. 
Again, google solar panel connections.  Eventually one of the web sites or Utube videos will make sense.

### ⭐⭐⭐⭐⭐ Amazing product!
*by J***N on May 24, 2025*

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!
