If the problem is actually coming from the transformer (my case), bonding neutral and earth at your meter or panel won’t really solve it. That connection only ties them together on your side.menzukii wrote: ↑17 Oct 2025, 16:29Here in Mexico, the standard is to connect the neutral and ground at the base of the meter to maintain a 0 V reference and divert stray currents. Now I suspect the connection between neutral and ground may be poor.
I've already solved all the problems by using LiFePO4 batteries, but I'd like to be able to use my home's mains electricity.
The neutral at the transformer is supposed to be the main reference for the whole line. If that bond at the transformer is loose or resistive, the neutral voltage can drift along the entire feeder. Any bond you make at your house will still be riding that unstable voltage, so you could still see a few volts between neutral and earth when under load.
Basically, a house-side bond only works if the transformer’s neutral is solidly grounded. If the upstream bond is floating, the real fix is for the utility to properly re-earth the transformer neutral.
