Well, inverter ended up in new utility room. I took note of what copec said regarding the unit trying to maintain a certain temperature range to lengthen component life. I am choosing not to try to add any fans for the time being. The rockwool insulation keeps the room very quiet and you can...
We don't get much snow here in North Georgia, but got a little last night.
When walking the dog I noticed that the array had a good inch or so of snow covering it.
I thought that the temperature would have to warm up some to clear the panels so I would not be getting any production until later...
I finally got to test the possible replacement fan. (Noctua NF-A8 ULN) The Noctua is silent compared to the ambient noise while the stock fan produces a very high pitched loud whine. Note that the 3 pin connectors have different pin outs, so that has to be changed should anyone do the fan...
I got to travel to where my inverter is stored and took a pic of the fan model number.
Since I now know they are 12vdc, I can use a pc supply to test the noise level and compare to possible replacements.
I can do this before I mount the unit to get an idea what approach to take. Also looks like...
Black is normally common and Red gets moved to whatever mode you are reading. At least in my experience.
And +1 for possible blown fuse in your meter.

Using Solar Assistant. I can only see total battery voltage. The individual cell voltages never showed on the bms page in the Deye menu.
Only total voltage and temperature. But while I was there I checked the battery states with the Seplos displays and everything was staying in sync...
Is it possible to get a stock update as to what is available from the Houston location?
Will be ordering in the next couple of months and would like the option to order from Amy Zheng and company.

The breakers are for safety/convenience. The main house panel and critical loads panel are 65 feet away. I have not noticed any swelling.
My cells are Eve 304 amp\hr from Amy at Docan. Shipped from the Houston warehouse last year.

Could be coincidence but, the ratio of your 108 to my 144 would be a ratio of 1.33.
Multiply your voc by that and you will get a value right at 50volts.
Could be that your cells are larger, but same voltage. (higher current capability)
Looks like your short circuit current is about 1.33 times...
Well it looks like the Mrs. is going to insist on the inverter being installed in the carport utility room rather than the basement.
This will add to the length of some of my wiring runs. 8^(
Not sure if you answered this in the original noise question portion of this thread, but did you...
The room is humidity controlled. (basement) So I am not concerned with condensation. Also I do not think a running inverter in an inside space would reach dew point temperatures. (even with venturi effect)

I had a similar event and found a bad (intermittent) connection on one of the bms sense wires.
I got lucky and happened to see the cell showing low voltage and upon wiggling the wire, found the bad connection. The sense wire had been extended to reach the terminal and I had done a poor...
What I meant for NPLC is (number of power line cycles). It is the integration time based on line frequency.
Since you don't require fast scanning, 50 - 100 would allow more time to for the integration of each measurement, providing a better measurement. 10 PLC is 1/6 of a second at 60 hz. I...
Very nice!! I am thinking of adding fans to my 8k Deye when I install it later this summer.
But of course it has side fans rather than top and bottom flow.
Kid
Copec stated in another thread.
So I guess if this is accurate you would need to monitor your inverter temps to see if additional cooling was indeed required to prevent exceeding the above range.
