PowMr60A MPPT Solar Charge Controller, 12V/24V/48V/160V(Max) DC Input, Bulit in LCD Display, Support 12(Max) Solar Regulator Connections, Work for Lead-Acid and Lithium Batteries【Parallel Version】

Build quality seems sturdy, the size is surprisingly small for how much power it can handle. Charges my batteries well with good control over the charge. Not very loud, easy to install and the best bang for the money I could find.

It is a good buy, it was a task with connecting it and getting it right but when I get pass that hurdle I can't complain. It's working well. It worth the price and I already start recommend it.

I bought several of these units in 40A and 60A versions -- from both Amazon and another online marketplace (all sold as New) .. of them, .. both 40A versions don't seem to work properly, and now neither of the 60A do. (one worked great for a bit, but then completely died, killing my remote camera setup :( )Note: some folks have had trouble with the wifi box. I didn't really, although it seemed out of 6 dongles, one didn't really like to connect. The Ali cloud doesn't seem as reliable as it could be for the connection, but I'd say the WiFi was about 91% reliable. That wasn't my issue.I am familiar with MPPT controllers. The issue I have with these is controllers is that with 400W of panel in full sun, they would only send about 100W (if that, often I saw as low as 20W) to the batteries.The batteries would report 13.6V or 13.2V or whatever (based on how full they were - this was mirrored using a meter or the internal BT BMS on the batteries) .. however, these dang iPandee eSmart3 units kept thinking the voltage at the battery as 14+ volts, so it thought the batteries were full!!?? I tried messing with settings a bit, but these should just with with the Li settings..Another issue I have is with the monitoring of the Load within the unit -- I have two 12v cameras plus some other 12v gear on my pole -- the cameras together draw roughly 1/2-1a during normal operation, and the unit didn't catch any of this. The cameras were on.. the current was flowing thru the Load section of the controller, but no monitoring occurred.I've tried the Explorer series from iPandee (sold as a different model here) and haven't had any issues. So I suspect there's some issues either with internal components here or the mppt algorithm itself.The controllers are slick for the interface, but just not reliable enough if they're being left alone off-grid. If you had this unit in your RV and could reset it, I guess it could be worth it.

This product is very simple to program . Satisfactory service no issues for the past2 years. Still in working fine

The media could not be loaded. I do like this MPPT, as a solar beginner was a good choice.i got this "PowMr 60A MPPT" Upgraded version.2x 590 bificial Solar panels (Google for "BSM590M10-72HNH")VOC = STC: 52.04 - NMOT: 49.05ISC = STC: 14.37 -NMOT: 11.62x PUPVWMHB 12V 100Ah LiFePO4 Battery in series 24V (actually 4 but did the test with 2 first)Note: the 60 AMP and 160PV input is only reachable if you use 48V battery setup. (dint test it)my setup was 24V and is possible 105PV input. in my test i got up to +/- 84.my setup now is in paralleld and amp is about 38 and 40, most was 38/37/36 Amp and watt was about 400 to 1.1kw.I do live in the Caribbean where we have allot of sun.I tested this setup for 3 weeks and this little mppt did charge my 2x 12v battery that was at 30% each starting from 9 pm and at 10:30 some times at 11 am batteries was at full capacity.i wish you could change the boost time becuase this will overcharge the battery even tho the BMS will kick in but it is to long 120 min, the work arround that i do is changing Battery settings from L08 to L07 so it keep charging the battery in a low voltage and keep using my inverter, when in boost mode it will go over 29.2v about 30V and my inverter will shutdown.for the rest this is a good MPPT for a small setup.Now i did order a bigger MPPT/Hybrid the "POW-LVM5K-48V-N" becuase i have 8 more panels of 590V and VOC between 49/52V this little MPPT can not handle all the VOC Volt.hope this info will help you.

Exactly what I was looking for

MPPT is the only way to go! I've been using PWM controllers for years and they seemed OK, but this controller put them in the scrap heap. As I sit writing this, it's VERY cloudy outside, fixing to rain. The batteries are charging. Wouldn't have happened with PWM. Now I'm not saying this particular unit is the best, don't know, but it's reasonably priced and performs well. Fairly easy to install, comes default for flooded acid and has a coupla other preset, lithium, gel, and a custom, which is what I use. The manual is what you expect nowadays, but you can figure it out. The cable openings could be larger, but the all seem to be small anymore, I like large cables for DC current. Good bang for the Buck!
