Generator/Inverter Wiring!

Only has one 240vac output.

So, here's what I'd suggest.

Use a sub panel with breakers for the house and heater
Plug the sub panel into the generator, and only switch on the heater when you need it, and off before shutting down the genset
this was an interesting tidbit from the website

" A. Upon test, we found that they trip out at 24.955A, with the incoming comfortably running at 21.7A.

How about a link to your generator ? if it has several output connectors, one can be connected via a relay, to the water heater. You never want to let the generator wind down with a Load connected. The inverter will disconnect when the freq/voltage goes out of spec, but the water heater needs to be manually disconnected or have a relay take it down.

The compact series does indeed has only one AC out. In your situation you will need separate AC distribution before the inverter for the immersion heater, as you described in your first post.
When you mentioned the generator of 6kw, I assumed you got at least a 3kva multi or quattro.

You have two AC out on the inverter, one is active only when AC in is life; use that for the immersion heater. Is in the manual. What model of Victron do you have please?
Also the bonding for the neutral to earth is done internally via relay so you can break when AC IN is active. You just need to tick the box in the settings menu.

Victron Multiplus Compact 24/1600/40/230ac

Only one AC in AC out. 😕

Hello Anthony,
I have a similar setup in a off grid with a multiplus and genny.
I wired the genny straight to AC in on the multi, and AC out is feeding the main and only one AC distribution board. Any excess available power from your genny will just pass thru to the loads, no need to wire into two separate board, because it will only be life when the genny runs. Off grid makes no sense.
Besides , having only one AC distribution for your loads, you can take advantage of the very useful future of the multiplus/quatro: power assist function.

But when the generator is not running that would mean I would be trying to heat a 3kw immersion heater with an inverter?

It provides useful information to the other people trying to help him....reading through the posts most people thought it was a US install and it is not and thus likely wired different. I am also letting him know there is a difference and that he can't just assume all diagrams he finds will work in his situation.

Anthony, you want help but are short people(not being friendly)....not a good combination. Maybe you should hire an electrician. Honestly your original post has very little information, maybe you should reread it.

They last part they are talking about is called bonding. In the US we are required to connect the neutral wire to the ground wire at only one place, this is called bonding. You are in UK so you guys don't use 120VAC so you don't have a neutral wire. I really don't know your answer but a local electrician should.

Good Luck

I don't agree that Anthony was being short. He also wasn't asking for help. He merely asked for feed back. There is a difference.
Furthermore he stated he was in the UK, so how does talking about US practices provide useful information?

[antonycurley]

I'm not being short - I do apologise if it came across that way.

I just tried to lay to lay it out basic in steps of how I thought it should be wired and it seemed to me that it just strayed away from what I was asking.

Anyway. Thanks for the input.....

I'm just wanting to know about wiring it up as stated In my original post!!

[antonycurley]

Ok. All a bit above my head at the moment. I'm in the UK. It's 240v. I have live, neutral and ground (earth).

I tried to keep it simple at the outset but it's all got a bit technical. 😂

4 wires from a generator!!?? I think you might mean 1 cable into a 'breaker panel'...

The intent, I believe, was to make clear that whether loose wires or cable there need to be four conductors: L1, L2, N, and EGC (ground).
And if there is a ground to Neutral bond at the generator you either need to disconnect that bond or make sure there is no similar bond anywhere else in your AC system. Otherwise you will have problems with GFCI breakers or receptacles in some locations.
