A real bargain for a 500V PV charge controller
Unit works great. I use panels with max Voc of 24v, so I can put 20 in series on one string.Be aware of the input current limitation: It can only use 18A of PV at 460v, so if your panel max current is 10A you'd exceed the device limits putting two strings in parallel.The fans are loud, as others have mentioned. But the fans don't run at night when there's nothing coming in from the solar panels, so not a sleep issue.The user interface menu 'system' is typical: minimalist but completely functional.I'm very happy with it.
Better then expected
I have had this controller for a few months now and it does what it says it does. Yes fans are loud but nesscary to cool the unit when sun is out. I have 2400 watt 48 volt setup running 50% of my house and dropped my bill 300 a month. I switched from a all in one inverter controller to this and I am very happy my batterys never go below 51volts even on cloudy days
Not good
I must have gotten a bad one because it stopped charging the batteries after the 1st week.It also makes to much noise with the fan.
Best on the market 100 percent hands down 900 stars
Finely a company that knows how to build solar controller. This is a top notch with the fans it needs to cool easy set up and let me tell you. 140 amp it handles the power like a champ. Spend the money and forget the cheaper ones I have had them and they are not worth it. 25 stars for this unit I will be buying 2 more. Update on my first one still going strong so I bought a 2nd one let you know it does
Great product
Works great and easy to install
Only buy this if you absolutely know what you are doing.
First opinions, haven't hooked it up yet, but wow! The jank is strong with this one. No reverse polarity protection on PV or battery. No overcurrent protection on PV. No ground fault detection, no disconnecting means of any kind on input or output, other than a naked, unmarked ANL style fuse on the battery side. 500 volt input capacitors and 63 volt output capacitors mean the advertised ratings should be taken as absolute maximum. Appears to be a single stage LLC with synchronous rectification, so it should be pretty efficient, but the chonky common mode choke on the input says it's probably noisy as heck. Overall, three stars. May update this review after I run it for a few months.
An honest appraisal
Bought this to add to my recently expanded panel system, and am pretty happy with it. This 6.5 kW unit is ideal for people who want to bring a lot of power from their solar panels as high voltage and low current. That can be very advantageous. If you are going to use it this way, make sure you understand how ground currents work. If you don't you might get yourself electrocuted. No room for mistakes at/above those voltages.Pros:Handles 500V VocMPPT tracking works good, and responds fast.Really generates 6.5 kW of power (at least with 390 V panel setup)On/off fan keeps unit cool effectivelyDoes shut down when battery voltage reaches shutdown setting.Back light is good and does not turn off too soon.Connection terminals are pretty solidSettings good from beginning and fairly idiot proof.Cons:Fan is loud, REALLY loud. It's not obnoxious but you can hear it from 30 feet away in open air.Readings are off by about 100 WDoesn't directly tell you when in float charge mode, but it's not hard to figure it out.Buttons are a bit hard to press.You can't change the voltages (you can control current). This is actually a good thing for inexperienced users, but I would like override capability.Pay attention to:500V Voc max, not 100, 150, or 160.No Inverter. This only charges.Only works with 48V and (based on menu options) 24V systems.I initially used silicone jacketed 4 AWG pure copper welding wire rated for 150 Amps to 75 kWh battery bank. Wires got quite hot after running 120 Amps for awhile, and unit can deliver up to 140 Amps. It worked but switched to 2 AWG tinned copper. Screw up your wire sizing (too small or CCA) and you will have a fire. Don't keep your terminals tightened properly and you will eventually have a fire or fried components.Conclusions:This is my second PowMr unit. I also have a 5kW 110V MPPT controller/inverter that has been running nonstop for 13 months. I like both units. This 6.5 kW unit responds faster but the 5 kW unit runs much quieter. I like the MPPT tracking algorithm on this unit.Bottom line: if you want/have a high Volts low Amps setup then this is an ideal unit.
Does what it says in the ad.
The fans are pretty noisy but it certainly does the job. Its in my basement so it doesnt matter about the loud fans. The instructions could be easier to understand, but i did get the main things set up. Only running it for 3 weeks, so not sure about how long it will last.Dies what it says so we will see.
