Growatt spf 5000 es 3 phase

[terkazarian]

Hello all

i've installed 3 growatt spf 5000 es as 3 phase system, for now the only input is the battery.

Once i've turned on 3 of them, it shows like it operating an has an ac output, but when i check the ac output with a multimeter, there is nothing.

I'm attaching the screenshot of the settings, including the firmware versions (2 are same, the third is different firmware).

Maybe it's a firmware problem? if someone can provide an info about the latest firmware of this units it will be great.

Thanks
