10A MPPT Wireless Solar Charge Controller with BT, Bateria Power 12 Volt Phone APP Intelligent Control Solar Regulator with LCD Display, LED Indicate Light for Gel AGM Lithium LiFePO4(Sunrock 10Pro)

I bought this controller after purchasing a previous solar controller that did not work at all. Simple directions: Connect to your battery first, then your solar panel. The controller lights show the charge level of the battery, and the LCD display show the voltage and amps going into the battery.I use this controller to provide lighting in a shop building that is off grid. I have one 100 watt solar panel, and a deep cycle 12 volt car battery. When I first installed the system, the battery was at 50%. I connected five 60 watt 12volt bulbs on a switch, and I have one 100 watt bulb that stays on 24 hours. When I checked on the system a few days later, everything was functioning properly, and the battery was at 100%. This system has been installed and working properly for about a month now. We worked in the shop all day yesterday, and the battery never came off 100%. For what I'm using it for, it's been a perfect application, and performing exactly as I need it to.

Receieved my item in mint condition; works great; protects my investment; displays important information; the controller has information imprinted to show where battery goes and where solar panel goes;

Has reverse polarity protection on the solar panel side(old connector was wired backwards for the PWM controller this replaced)Sucks up 2 watts all the time. It never goes to sleep once the sun goes down. LED indicators are on all the time.Less efficient than the old pwm controller, but provides a steady current. Lower voltages on a lifepo4 battery, I could get 12.5w on the pwm, but so far only see about 8w through a battery monitor.Ordered a larger solar panel, as the fake 25w panel only put out 12.5 watts and was no longer enough to keep the battery charged, as my power usage went from just 2-3 days of use to 24/7. The higher wattage panel may better benefit from the mppt over the pwm.I'll update this review with the new panels data. If the PWM still does better, this charge controller will be returned.Update 1:After a few days, the charge controller stopped using 2 watts 24/7 and now goes to sleep when it gets dark.Update 2:Got the 100 watt panel hooked up in place of the 12.5 watt panel and it makes the same power on the MPPT. A measly 12 watts. Works fine on the PWM controller, but very not power efficient. Probably only getting 30 watts from it on the PWM. Sent an email for support. Maybe the MPPT adjustment is super slow? I have two Growatt SC48120-MPV and they adjust fast and throughout the day.Update 3:I just today discovered that past me is an idiot. I had installed a very small wire to carry the charge on the 12.5w solar panel, and it worked fine for that, but I didn't consider the small wire when I increased the solar panel size.Properly sized wire I'm getting 4 amps on this MPPT and 4.5 on a Victron 75 |15.Even the PWM was getting 3 amps.

I'm very happy to find such a small and low priced MPPT charge controller. I wanted a small controller to use with my QRP Ham set up and this perfectly fits the bill. The only down side is that this unit is noisy. Easily fixed though. Just take a 240-43 mix toroid and wrap the power cord between the controller and the radio with as many turns as you can get on the toroid and the noise goes away. Now it works perfectly and I have not spent $140.00 on a Genasun controller to get an efficient and quiet, small charge controller. Easy and cheap fix that now does not cause any noise in my transceiver. If you are not using this controller for something like a ham radio. Maybe just to charge something like a battery or cell phone, the noise it generates should not cause you any problems as is. Most all charge controllers generate some noise unless you get one like the Genasun, which is very expensive. Ham operators, try one, you'll really like it.

I had a gate opener that allowed my battery to go dead every night. I bought this 10A MPPT charger to by pass the gate opener circuit board, and it hasn't gone dead yet. The circuit board for the gate opener was $275. The solar panel plugged into the circuit board of the gate opener also but would not charge the battery. I disconnected the solar panel from gate opener circuit board and inserted the 10A MPPT and saved a couple of hundred dollars. I feel like it will last much longer than the gate opener.Depending on the weather through out the year I may have to up my 10W solar panel to 20W or 25W and add another battery, go with a with LifePo4 23AH. No problems so far though. What ever the case I will use the 10A MPPT.What I know for sure is that the 10A MPPT controller gives me plenty of room to work with.Tech support is fantastic. I would asked a question and get an answer before I finished eating.Love the product and will use this company again.
