Generator/Inverter Wiring!

[antonycurley]

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?

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. 😕

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.

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.

Only has one 240vac output.

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.
