looks good, but cheap internal connectors caused high resistance and melting of the wire inside Dont Buy!!
5 of 6 found this helpful On the outside this charger looks very nice, but when I tried to charge a 6v 225ah battery the charger would not provide power. I then tried it on 12v and the same result. After checking the fuses on the DC side and then the AC, both were fine .
so I opened it up and found that it looks good on the outside but the inside is not. I found broken AC mains wire to the coil, so I repaired it by cutting off the connector and applying a new crimped socket. There was also a big burn on the main DC out from the coil which supplies 6v and 12v DC power. The socket was not in good contact with the wire, which caused a resistance creating the melting of the crimp and wire. I replaced that with a strong connector and now the charger works fine.
If you are not electrically minded and have no experience in chargers, coils and rectifiers, don't buy this unit!!!. This may have been a one off but, if that mains wire had touched the inner metal case I might not be here now writing this!!! Please don't open this up if you do not know what you are doing!!! on the plus side. It has a good full wave rectifier and heat sink

a bit cheap really. meh
1 of 1 found this helpful the bag seems really good quality but the strap broke off when I placed it on my shoulder.
the stitching was very badly done, And there was some weak glue which would not hold so, I had my son mend it for me. On the plus side, The bag is stylish light and smells like real leather.
it has loads of zips and plenty of room for cards and phones

real world power
This 60a mppt charge controller is a great alternative to the outback and midnight charge controllers 1 is price this mppt is only £90, where as a midnight classic will set you back £650. the powmr 60a ppt, can compete easily with anything out there today.

cooling this unit has a active cooling using a fan that comes on at 40c and goes off at 30c or around that temperature. the fan sucks hot air out from the bottom through the top, there are videos saying to reverse the fan so it sucks air in. this is incorrect as heat rises, and the idea of the fins on the side are to let cold air in to cool the mppt. there are also people saying that the fan burns out to fast. I have 4 of these units at 24v 1320w for 4 years and have had no problems thus far. its reliable and well built. I keep my units cool via mounting them on blocks allowing them to have air flow behind them.

build quality is good its heavy! it has a good heat sink on the back if mounted correctly cooling is not a real issue however it is a fan and fans fail at some point! so its best to keep an eye on it. it has 2 + and 2 - for the battery and the same for the solar inputs
some say the connectors are to small but its efficient and in this world of saving materials it does make sense the 2 - and 2 + are for higher loads so, 4 200w solar panels wired in series which equals to 2 + and 2 - then has to be wired in parallel before it gets to the mppt input. this, balances the load to the unit. you cannot wire a 600w un balanced load
to it e.g 200w on one leg and 400w on the other this imbalance with cause a short inside and could catch fire don't do that!

interface
this ppt has a good clear interface on it allowing you to set various settings like voltage cut off bulk and float charge. the powmr however has to be turned off to apply the settings you want so in order to do that, turn off the solar and then the controller, wait for 5 seconds and turn the mppt back on again. for me, this sometimes takes 2 power offs to get it to apply the settings.

fake vs real
this powmr is known to be a fake make sky blue. this may be so, but even though the powmr has v113 firmware and the make sky blue has v117 or v118 with wifi the powmr tracks well within 0.5 seconds or less. it does however need to update for voltage recognition. the powmr on a 24v battery only shows up as 12v. you have to double the reading for your set voltage. the make sky blue however reads the 12v as 12v and 24v as 24v. plus you do not need to turn the make sky blue off to apply its settings it can do that on command entry. the make sky blue also has the feature to allow offsetting the battery voltage to get the right reading of the battery. the powmr does not have this feature, this can be fixed in the powmr with setting the voltage of charge to lets say on a 24v battery to get 29.6 you would need to set the controller cut off voltage to 15.2. the powmr shunt is also a little off when it comes to accuracy reading 40a but in reality its 35a. however im in the uk and getting the make sky blue is hard because you have to order it from china or America. I bought the powmr because its in the uk if I had ordered a make sky blue from America and it was DOA on arrival I would have to send it back having to pay import duties and postage which, was not logical to me.
my powmr is connected to a 1320w array in the uk I read on a cloudy day around 400w of power when there is sun I get 1350w peek performance utilising all the panels connected. I hope this helps someone all the best.
