Tension at a SPD for Solar Power System

TL;DR Summary

Surge Protection Device (SPD) for Solar Power System

Hello there! I am using a Surge Protection Device (SPD) for Solar Power System. My home uses a 3-phase system (380V and 220V at each phase). What should be the tension between the phase and ground at the SPD? And between the ground and neutral? Should be any tension at all? God bless all. PS. My English is not so good... Sorry

Are you asking what voltage rating SPD you should install for this Solar Power generation system? Does the manufacturer of the system have a recommendation?

Are you completely off the grid with this solar power system, or do you have the required Anti-Islanding switching equipment to be able to use both?

There are electrical codes applicable in nearly all locations. The codes cover home generation as well as power bought from the power company. You must follow the codes, they are mandatory.

Unfortunately, codes around the world vary, so we can't advise you here on Physics Forums. A local electrical contractor or a licensed electrician is what you need. Not Internet advice from strangers from multiple countries.

And with that good advice from @anorlunda this thread can be closed.
