Can you share a picture of your connection. Check your your breakers and fuse as mentioned earlier if they are good. If possible, power up your inverter with shore or generator power before switching on the breakers to the batteries from the inverter. This worked for me with my Victron inverter...
This is also true in my case. I have 302AH, 272AH & 280AH batteries connected in parallel with different BMS and the current during charge and discharge were very close.
Most likely your BMS is faulty. The power output should be zero, I have switched off several times the charge and discharge of my (JKBMS) without issues when replacing cables to my inverter. I once had issues with the Heltec BMS (with 1A active balancer) I bought that didn't last a week but had...
I think you need to use the return key after changing the parameters, then click on download before selecting set to all. That's how I was able to change the default battery capacity for mine.
yes it is. This was custom made by @Amy Wan (Luyuan) for my 16s setup and SEPLOS BMS. This picture (couldn't get a better as I have been busy) was before it was shipped and looking from the front, the cut out is where my SEPLOS BMS will fit into. Unfortunately, my BMS is part of the faulty batch...
Mine arrived about 2.5 months to Nigeria, all well packed including the custom box for the batteries. I am really pleased with this purchase and as always @Amy was super helpful all through the transaction.
