Hello,
I need help with Growatt SPF5000ES ground/neutral bond. The more information i see/find, the more confused i become. It looks like:
a. ground/neutral bond is different in the USA vs Europe (please correct if i'm wrong), i live in EU.
b. Growatt under the same name "SPF5000ES" makes two different inverters. One with build in G/N bond for USA, other without G/N for EU. (please correct if i'm wrong).
I have two SPF5000ES (not connected yet), and willing to buy the 3rd one. Currently one item bought from Poland (EU), other bought directly from China.
First of all, is there any way by looking in to this inverter understand does it have G/N bond or no?
Second, should i do G/N bond or no? If yes, where? I live in Europe. As i understand in Europe there is no need to do that. But what if one (or both) my inverters already have that bond inside? Or maybe i wrong, maybe i need it?
I love electricity and play with it since childhood, but i'm not certified electrician and i never ever before had anything with G/N bond. As (if) USA vs EU have different rules already bit confusing, and if growatt makes two different models under the same name, everything becomes even more confused. My setup will be connected to the city grid on winters. But on summer i would like to turn OFF city grid and live on my own off grid.
Also what the worst could happen if i make a mistake here?
P.S. Also, i know, that if you in the forest with gasoline generator, there must one of wire grounded to the earth, so the other would become the live wire. But this is probably different story.
Thank you.
