[Upgraded] 30A Solar Charge Controller, 12V/ 24V Solar Panel Regulator with Adjustable LCD Display Dual USB Port Timer Setting PWM Auto Parameter

I was very pleased with the controller it worked perfect thanks for the fast service

So easy to use that you don't even really have to change any settings. Does not work with lithium ion batteries or batteries that have a BMS controller in them because this already is a BMS. I have 20 amps of solar panels feeding it and it maintains a lawn mower battery that I use for an inverter and 12 volt lighting in my safe room.

It seems to be working just fine. I do wish they would make the instructions in the manual for the different menu settings with detail about what every function and setting is for but I just googled it all.

Very good and long lasting

Erratic volt readings jumping between 17v and 13v. Load ON/OFF button (right button) does not work. Battery is a good flooded battery and type was set correctly at b3. USB port won't charge my 10 inch android pad. The "bolt" icon shows next to battery level but the pad keeps draining power. Detail screen still says "x h x min left". (it should be "charging - x h x min until full")I have 2 other similar controllers I bought in 2019 and 2021. Neither of them have any problem. Before I threw this trash away, I took it apart and found: (1) its circuit board is much smaller than my older controllers although the outer shell has same size and color (2) it does not have a temperature sensor while my old ones have (3) its back plate is a piece of plastic while my old controllers have serrated aluminum.

I have several of these currently 2 in use. One for chicken coup fencer and led light strips. Less than 50w...now the 2nd I have 3 50w 12v lights in my shed hooked up..they were with a switch nicely..however I went to add a 4th today. The controller fails over and over...large 27 and 29 deep cycle battery on each. 200watt solar charging..adding the 4th light to equal in theory 200w of usage shuts it off..not sure how these actually work but if their made to work load = solar energy their worthless. Might have to consider something else for more power..

Certainly! I apologize for the confusion. Here's a consolidated review with two paragraphs:I recently acquired the 12V, 30 Amp solar charge controller as a backup for my primary system, and although I haven't had the opportunity to use it yet, my initial impressions are positive. The controller appears to be well-made with a sturdy build, instilling confidence in its potential reliability. The straightforward installation process and user-friendly interface are welcoming, especially for someone like me who is still navigating the world of solar setups. I intend to pair it with a 25-watt solar panel and a lead-acid battery, and while the real-world test is pending, I'm optimistic about its performance based on its promising features and durable construction.In anticipation of its application in my solar energy system, I appreciate the controller's thoughtful design and versatility. The ease of use and compatibility with various setups make it an attractive choice for both beginners and experienced users alike. I look forward to seeing how well it complements my solar panel and battery combination and believe it's a wise investment for those seeking a reliable backup or alternative solution for their solar charging needs.

Arrived in perfect condition and in great time and a great value for the money
