My inverters were showing code 71!, so I swapped both 6500ex inverters for two others I have and the same issue was occurring.
I have 12 Lifepower4 48V batteries in my setup, I am doing some testing today (and through the weekend) as it looks like even when it is showing over 80%SOC most of the batteries are putting out less than 46V and not powering the inverters. I am working on pulling one at a time for testing however 4 of them started emitting a buzzing sound when turning them back on.
Any assistance with testing procedures for this issue or thoughts on the noise appreciated.
