I am using 2 RuiXu Lithi2-16 batteries with an EG4 18Kpv inverter.
My inverter support told me that I need to update the battery firmware to establish better connectivity with the batteries.
How do I find the correct firmware?
How do I update the firmware?
Thanks.
Yes, I had to power off the breaker of each battery when I installed the firmware. I would suggest doing the secondary battery first, but it doesn't matter as I did the primary first and all was well.
You do need to disconnect the comm cable in order to attach the usb-485 cable from the pc to the battery.
If I had had grid, I would have switched to grid while working on the batteries. It all went smooth with me, and I'm sure yours will too.
