Our shore power is 240v / 50 amp and is broken out into to 50 amp circuits. Our generator can out either 120v or 240v.
We don’t have any 240v consumers onboard and only use 120v.
We have 1000ah at 24v of lithium batteries.
What is the easiest way to utilize our shore power to run at minimum a 5000 watt inverter and also have our generator as an option?
Is there a quattro or multi that can accept 240v but output only 120v?
No, the ac input and output are directly connected so they are always the same.
2 ways around this.
Couldn’t we just use one leg of the 240 volt and limit our shore power to under 50 amps?
Not familiar with US ac configuration.
You should be able to draw 50A between L1 and N.
As you write that all users are 110V this should be your regular power flow.
The multiplus ii 2x120 is especially made for these applications
As Ludo said, the Quattro 24/3000 2x-120V is one option for you. However, with a large battery bank I think you would be better off with two Quattro 24/3000 or 24/5000 so you have more battery charging capacity when running from generator. This would reduce the generator run time and use the generator more efficiently. You would configure the Quattros in split-phase mode and have one feed one 120V panel and the other feed the other 120V panel, while taking in your 240/120V split-phase shore power and generator output.
The Quattros would eliminate your existing transfer switch and you could likely automate the start/stop of the genset as needed with a GX device. Your local Victron distributor or installer can help you design such a system.
