VOV generators

[Derlyn]

My way of quickly checking if it's vov or not. If both lamps light up it's vov and cannot be used to connect to the installation.

If it's a vov, don't even try and modify it. The centre tap is not accessible unless you want to strip the genny into a thousand pieces to get at it to disconnect it.

Hi Leecatt

Check out this attached thread. There's a photo of exactly how I've been doing it all the time, successfully.

The bridge can be seen. It's the black wire with yellow lugs.

All the generators that I've opened so far are identical. Only the branding that differs.

Just remove the round end cover of the genny and it's easy peasy.

Tip: There are 2 thick wires coming from inside the stator. The brown is live. White is neutral. Just bridge the white to earth.

Cheers.

Thank you for this. Another question that I have is, if this is the correct way to wire it to be 220 volts then why doesn't it come wired like this in the first place?
Do you have a wiring diagram for your gennie please?

Remember that generator is manufactured as a portable unit where neutral earth voltage is not important. That's why it's not bridged. We are just using the generator for something it wasn't actually manufactured for.

By bridging the neutral and earth, you are now changing it to a standby generator to be connected to the installation where the neutral earth voltage should ideally be zero.
