OK, a partial solution. Under the Growatt are two circuit breakers, AC Output and PV Input. I had both on. When turning them off and having the inverter off that voltage across the battery input to the inverter drops MUCH more slowly. I will continue this experiment tomorrow. Thanks for all...
Definite newbie here!
I have a 16 cell lifp4 battery and am wondering what is the best/safest(for the cells0/fastest way to top balance these cells?
I have a small power supply on which I can set the voltage (ie 3.6v) and the current with the cells in parallel but it takes a very long time to...
I am still trying to communicate with my JK-PB1A16S10P bms with no luck so far.
I am using a USB to Ethernet dongle but the computer (JK software) does not recognise it as a com port.
Which dongle should I be using frm the com board of the BMS to the computer?
Thanks
Also, notice in your pic from Andy that the 3rd plug from the left has a NC on the 3rd pin!. I am switching the wiring between the first and third plugs so that I get a B0 c0nnection. The reason for the NC on the 3rd pin of the 3r plug is that the bms shows two connetions to B8 and only one is...
After checking all my connections and continuity, I have come to the conclusion that my external (locked) box at the meter has bonded neutral and ground and that my interior main panel is really a sub panel with no N-G bond. Thanks for all the advice on this issue
My Growatt SPF 6000T DVM is repetitively shutting off solar input, beeping and then trying again. Seems to happen when the battery voltage gets to about 55.8V,100% SOC on my lifepo pack. I have all the parameters set using the recommended settings and I can't get it to stop this behavor. I am...
Herb, This is exactly the conclusion I had come to. I have been looking for an appropriate external cooling fan to prevent the internal fans from energizing. Has anyone done this with a Growatt successfully?
Thanks
