Yes. Red to positive and black to negative. But for the sake of the question, I will switch them around to see if that makes a difference. Raining here right now, so will check tomorrow and give feedback. Thanks for the suggestion.
I agree, check polarity first.
I'd rather you just check with your multimeter. Pull the + wire measure across it and the - wire (that is still connected to the SCC) and you should see positive voltage. If your meter can handle it you can measure the current too. You don't have to have the panels in full light if your meter can't handle the full output of the panels. If you see milliamps when you expect amps you have a wiring / connector issue with the panels etc.
. As suggested by AlanGriff, I disconnected the batteries, let them sit for a good minute or more and reconnected . I then connected the black cable to the positive terminal on the SCC. Let me tell you. I have never been so glad to see a green light since the last time I took a run to the beer store at five minutes to closing!!! The MT50 also showed the solar panel icon with the charge arrows scrolling toward the battery icon. I feel like the guy who calls an electrician because the dryer wasn't working. Only to find out the breaker was tripped. D'oh! Now, before I hit the post reply button, let me check that we are still all green. Yup after 45 minutes we are still green. Tomorrow will be crossed wires tracing day. Once again, thanks guys for your help. This has been a very "positive" experience indeed. ;-)
well disregard the above. The single panel started doing the same thing shortly afterward, 40V and 0.0A. It is definitely an intermittent thing - currently both panels in series are charging just fine, but it may be back to 0A anytime. I am working with Epever support, and hopefully I can get this thing replaced under warranty.
I am having this exact problem with my epever 6420AN. It shows pv voltage correctly at 110v but only 0.1amps. Did you ever get a solution to your issue?
@wgrippo have you made any headway with Epever support on the low charging current? I am having the exact issue and only just beginning to engage them.
It has been a long, slow process. I have been back and forth with Epever support for over a month. They requested videos and photos of all of the components of my system. I got lucky and was actually able to observe and film the MT50 display as the current began to rapidly climb and then drop to zero.
Thank you. I am considering just writting off the Epever. I think it may be more expensive in time and money if I have to ship it back to them and back again to myself. Will end up spending more that the unit cost me. I will trash it, notch it down to experience but will still raise a dispute on alibaba.
yeah, I might do the same. $150 lost is probably better than the hassle, especially since I don't need it anymore. I'm pretty happy with the Growatt 6000 so far. I've only been using it for about a month. I liked the fact that it has an AC input, where you can plug a generator into it to charge the batteries if you get a few cloudy days in a row. But I just realized it only takes 240V AC input, and my little 2200W generator only puts out 120V.
Funny, I had a similar response from epever. My issue was both PV and batt lights flashing green during charging. This is news to me however!! that the BN is NOT for lithium batteries. Huh? I got mine based on wills 24v setup. Now I find out it's not for my lifepo4?
Did you do anything to make it work again? I have the exact problem with EPEvEr 6240an.
It just had started by itself I don’t know if what I tried had any impact. it worked great for like 15 hours and it stopped again
I think the solar voltage “head room” needs to be several (like 5v) higher than the charge voltage. It’s possible that your SCC is waiting for higher voltage that it needs. Is there an input voltage range in the spec?
