Tension at a SPD for Solar Power System

Click For Summary

Discussion Overview

The discussion centers around the appropriate voltage levels and requirements for a Surge Protection Device (SPD) in a solar power system, specifically in a 3-phase configuration. Participants explore the necessary tension between phase and ground, as well as between ground and neutral, while considering electrical codes and manufacturer recommendations.

Discussion Character

  • Technical explanation, Debate/contested, Conceptual clarification

Main Points Raised

  • One participant inquires about the expected tension between phase and ground, and between ground and neutral, in their solar power system setup.
  • Another participant questions whether the original poster is asking about the voltage rating for the SPD and suggests checking with the manufacturer for recommendations.
  • A third participant emphasizes the importance of adhering to local electrical codes, noting that these codes can vary significantly and recommending consultation with a licensed electrician.
  • A later reply suggests that the thread could be closed based on the advice given regarding local regulations and professional guidance.

Areas of Agreement / Disagreement

Participants generally agree on the necessity of following local electrical codes and consulting professionals, but there is no consensus on the specific voltage requirements for the SPD or the original poster's situation.

Contextual Notes

The discussion highlights the variability of electrical codes and the potential lack of specific guidance applicable to the original poster's location. There are also assumptions regarding the setup of the solar power system that remain unaddressed.

TL;DR
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.
