Let’s see who’s knocking about on this forum as well, @Mbu1982 and @davericho have mentioned having Solis...

I’ve failed to get you some first-hand advice on this, @edsashley. 

@ArundaleP @davericho or @Jequinlan may be able to tell you about this ground voltage messaging…. I know I can’t!

Hi @edsashley @Tim_OVO 

Unfortunately I'm not able to help as my Solis inverter hasn't been installed yet, but would be very interested to know the answer to this, would appreciate a answer on this in this thread at some stage, all the best 

Does this link help.

Answered in a different forum. Apparently this is a breakdown in translation from Chinese to English. This is said to be the midpoint of the dc bus voltage, which does add up. This was also shown to me on a system designed in the US where they had a ground voltage equal to half of their bus voltage. 

@edsashley me being new to this tech I take it that this is normal and nothing to worry about or not

Hey @edsashley,

Any updates on this? Would you be able to send @davericho a link in private message to the other Forum you are referring to as they might find it useful.

Great to see our community members helping each other
