PowMr M60-Pro - How Does it Stack Up Against its Predecessor?

- Times change and I need to change with them, so here I am trying to get the new charge controller from PowMr working and see how it compares to the older HHJ-60a I've been using for years.

I know people like to buy this cheap (not necessary cheap price!) stuff but before you do read the manual. See what it can't do first. For lead acid charging, where's the absorption cut off time? Where's the tail current setting? Where's the equalisation voltage? Where's the equalisation interval? Where's the equalisation time? Similar questions can be asked for LiFePO4, LTO and NMC batteries. If the charger doesn't even have those basic settings, skip it. You won't be doing you battery any favours, regardless of chemistry or specific type, if you use a charger that doesn't even have those basic settings available either via the integrated front panel or an external display or a computer or smartphone.
The button controls on this POS are NFG! Still no charge, can't select battery type. The Bat led do not flash only lets me change the 03H to 24H setting. Chinese instructions are garbage.
Lol, had the same issues till I read the manual buddy. The C is a battery calibration function that allows you corre t the battery voltage if it's significantly off from the actual value
I attached an heatsink to my ProMr to help with the cooling. That seems to help the cooling. Honestly though I also have a Makeskyblue both are side by side, the Makeskyblue far more efficient.
After further testing mine, It appears this inverter is really only a 30amps MPPT then it becomes PWM over 30amps. Anything over 30amps going to battery, it drops the charging voltage (behaving like a PWM and doesn't do buck convertion) and goes from MPPT mode 4 to Absorption mode 7. My battery capacity was very low but it was only charging in absorption mode 7 because I had over 30amps. Immediately I removed some panels and reset the solar input, it went back to MPPT mode 4 and stayed in MPPT till it was near full
I have had one of the metal housing units for over 4 years now. Works great. Ordered another one for some additional panels I'm putting on my house. Only 2 250 watt panels on a 12 volt agm setup. It has very strange behavior compared to the old one. Acts a lot like this new unit you are showing. Goes to 7.0 almost immediately. Doesn't drop back to 4.0, no matter how low the batteries get. Got a replacement, does exactly the same thing, except the replacement battery volt reading is WAY off. Quite disappointed. I wish the new ones would work like the old one. I was going to try this new one you are showing in this video, but I've ordered a Tracer 4215bn after seeing some of your other videos. Hope it works out.
you have to put a high consumption for it to reach 700 to 800 watts of panels when it enters 8.0 mode it lowers the voltage of the panels and the battery stays at 13.8 in float mode
The c stands for calibration it should be set to the actual battery voltage. Im haveing the opposite problem with mine i have a 109 amp hour lead acid. I have 2 24v 200w panels wired in parallel and it stays in mode 7 and wont switch to mode 8 its been in 7 for a day now i have no load on the battery edit: finaly switched to mode 8
C is for Calibration
How much amp it can handle of dc load from dc terminal
So glad I found your video, cause I was having the same issues was driving me nuts. However, when I changed the c-number to the actual battery voltage it stayed in mppt mode,,,,Hopfully that did the trick,time will tell.
I have one of the old ones. It switches off charging when the controller reaches 75 degrees C. Then after it starts charging again. Im currently running on a 24v 200amp battery. Running 1800watt panels. Read out is 1.5kw and actual amp reading is 50amps. This is a very tuff controller. Its just works. I am very happy with my unit. Have it for almost a year now.
Experience with the older PowMr units was that they seem to work ok but 2 recent metal ones, both sent back, do the same as the newer model that you have. The system they were used on logs a battery voltage, charge current and solar voltage by the minute and, even with depleted batteries, spends most of the day holding the panels near battery voltage despite them having a Vmp of 30v. Now swapped for Makeskyblue with v118 firmware which seem to track flawlessly for about the same price but getting almost twice the power over a day.
Saw the powMr 60a was on sale at the same price of my OneSolar 40a. Went here to see if its worth it. Most reviews are crap so i really enjoyed you testing it at 60a and seeing it failing. I notised people warn of me mode 7 in other reviews in the comments. Please give an update if you fixed it with a cheap 80*80*10mm box fan or what happend.
The latest version of the newer type of 60 amp controller now has several choices for the lithium battery depending on how many cells are in the battery.
Did you diskonnekt the battery from the Kontroller to reset it.
I got two of these controllers one has been running perfectly fine for the last 7 months or so on a small lead acid battery bank no issues at all. The other one with all the settings done for a small lithium iron phosphate battery bank only worked for a couple weeks it would not stop charging the batteries no matter what settings i used. I tried it out on the small lead acid batteries and it wasn't working with them either it just kept charging to over 15 volts new version is much worse than the older version. I have four of the older ones two have been working for 6+ years with only the fans going out easy to fix though the other two have been going for four years so far .
Hello sir. The old powmr with fan and the new one without fan but with heatsink, which one is better please? And more efficient
How do you know when the batteries are fully charge on the Powr,and know when your home is getting straight energy from the solar panels?
I also don't put switches on my tiny setup, cause mines tiny. I set up my 3x 30W pannels in series once and found out 60v 2a DC can sting a bit.
