Review: NOT REALLY MPPT, but it does work for 12V and 24V installs - A year + later and still working well - I bought this figuring that it was not really an MPPT (the claim about it using amperage was a "clue", as was that it only operated 12 and 24v) - but a PWM type controller - but if I got lucky, then great. I was setting up a 12v system for experimentation and eventually migrating it onto my RV, or replacing it or other parts as needed. My set up will push a maximum of just under 30A at the controller, so I felt the 60A unit would be a good safety margin choice... remember that the warmer the temperature on the panels, the lower the voltage, but the higher the amperage. Always factor for those max/mins. So far, it has held up well even with an overheated space I am storing it and the batteries in. It does work well, it does report the voltage, amperage and temperatures fairly accurately, and it does work. So as a nice little PWM controller, it's fine. I held no illusions of it being an MPPT unit, but a lot of people will... so don't be fooled. It's OK, but know what you are buying. For the money, it's a decent little PWM unit, but no, definitely NOT MPPT. EDIT 11/2023 - I just was going back through stuff and thought I'd update - this little unit is still working fine charging my 2x 12v batteries. It's lasted through a cold winter and a very hot summer. Even with a small little 6" fan cooling all components, it's held up and works great. Upped to 5 stars instead of 4 because it's lasted longer than I honestly thought it would, and it just keeps going.
Review: Very nice and much better than expected - Working very well, and the amp reading is also very nice to have, let me know I wasn't getting as much power as I should be, upon checking I found a bad connection that was causing almost a 75% loss in amperage that my old charge controller showed no indication of. Follow up, as well as it was working it died at 34 days. This is 4 days outside the desertcart return window, considering it took a few days before I could install it it actually worked for less than 1 month. Who knows maybe I just got a bad one I will order a replacement. Stay tuned for info on replacement. Replacement wasn't needed, I disconnected it for about 30 minutes then reconnected it again and it appears to have reset itself, it is currently running just fine and all readings I have verified are again working spot on.

## Features

- 【Dual USB 100A MPPT Solar Charge Controller】 Using innovative MPPT technology high tracking efficiency up to 99%;Please refer to the information if you are not familiar with Mppt technology:There are many kinds of MPPT technology,Our Solar Controller Mppt technology is to detect the maximum charging current,not the boost type or the automatic charging of the solar panel voltage.
- 【Multi-function LCD Displays】This controller is 12V/24V 12V/24V automatically adapt,first connect the battery,then connect the solar panels,when you first use it, make sure the battery has enough voltage,so that the controller can recognize the correct battery type.
- 【Reliable Protection】Overvoltage, Short circuit, Overload, Overcharge, Over discharge protection function; Automatic focusing MPPT tracking charging, high charging efficiency, Non-stop detection during charging, bidirectional focusing tracking.
- 【Industrial-grade Master Chip】16AD sampling accuracy, temperature Charging current, discharge current accurate real-time display, power generation at a glance.
- 【Please Attention】Pls note the connection ways,Connect the battery first,then connect the solar panel(You can't reverse the order).The place that don't understand pls contact us,Thanks！

## Questions & Answers

**Q: does this not have a battery temperature sender? to avoid battery damage? is this actually mppt not pwm?**
A: This is a PWM, *NOT* a MPPT, and expensive for a generic PWM.  The irony is that Mr Ostrosky fell upon the fact that for cheap panels (17v) in parallel, a pwm is just as good as a mppt.  The standard is his 17v at 70ish degrees runs at 2v less when temperature adjustment is made since the solar panel gets really hot.  Mppt transforming 15v down to battery voltage vs a pwm dumping at battery voltage is essentially indistinguishable.  The mppt will only boost amperage a tiny amount over the pwm.  There are some good YouTube videos on this using quality lab setups.

**Q: is this actually a 60a, mppt negative ground controller?**
A: I been struggling with this handling 60 amp output too. I use 8 gage wire.  I beleive china means it can take a solar charging panel out put of up to 60A from what I have read. They are not refering to what all of are which is hiw many amps on the load side. The wiring inside unit is very thin. Like 22 gage. I am sure my trolling motor at 40 amps would cause this to melt away. Anyone know for Sure????

**Q: Does this unit come with proper wiring ?**
A: No

**Q: controller memory- Will charge controller retain my settings when I 'kill' the power while the unit is not in use?**
A: Yes, but it doesn't matter. It's a cheap PWM fraudulently listed as MPPT.

### ⭐⭐⭐⭐⭐ NOT REALLY MPPT, but it does work for 12V and 24V installs - A year + later and still working well

### ⭐⭐⭐⭐ good mppt 60amp control for the cost
*by M***G on August 4, 2024*

I have four of these controllers (3)60amp (1)100amp over a year I have had others low end quality (cheap price) that burned out in less of a year I have high-end cost one as-well (not china) I do R&D on green energy 1) pro: the price is right (not for large no-manage systems) 2) pro : it has some feature of a MPPT it will adjust V &A to the battery, same watts ( - ) use in the controller . ie: match output voltage high of battery and adjust current to make solar input watt the same , (PWM does not) 3) a 30,40,50,60,100 amp controller is ONLY for the max amp input from the solar panel, these controller only have a max out put of 30 amp (10 awg wire) to battery 4) pro : I like the NEW screen shows amp, volt, C deg less graphic (show number for my testing) with my other test equipment. 5) con: the USB don't work most of the time 6) con: the Kw use screen option is not correct don"t use 7) con: these do get hot if there is 20 amp or more go thru them (I made heat sinks for mine to keep them cool) heat WILL KILL and short the life of the controller 8) con: these are made in china and the safety margin is NOT there, like in other countries, if look at specification take into about 80% usable on max, do NOT think 100% or it will not last long
