Currently I have a Magnum 120/240 4kw 24V inverter + a generator which is running in 240V (though it can output 120V as well).
I have a deep well water pump 240V
I'm upgrading to 48V. Looking into using a Quattro inverter. Since there is no 120/240V Quattro, what would you recommend in my case to get both 120V and 240V?
Should I get 2 x 120V Quattros and connect them in parallel?
Or probably a 240V Quattro + transformer?
Many thanks for your assistance!
In my opinion, the best solution is to run two Quatros in split-phase mode. That gives you two 120 volt legs with 240 between them, like you'd find in a home electrical system. Your generator would then connect to the split-phase input to the Quatro pair in 120/240 mode.
You could also run a single 120 volt Quatro then create your split-phase output via an autotransformer.
Or a 230 volt Quatro adjusted for 240 then into the same autotransformer. Your generator would output 240 volts (with no neutral connection) into the Quatro.
Victron sells 32 (7600 VA) and 100 amp (24000 VA) autotransformers.
Thanks a lot Kevin. Also as I understand transformers cause some power loses, which is another plus for 2 Quattros in parallel
...generator would then connect to the split-phase input to the Quatro pair in 120/240 mode.
Sorry if it is a dumb question, does it mean I connect the generator to both Quattros?
Appreciate all your help!
Using a single, Quatro and a transformer might be a little less efficient but would save you money.
If you don't also have a grid, a Multiplus might be less expensive. It lacks a second AC input, but two Multis you can produce 6 KVA split-phase. Two Multi Compacts would produce 4 KVA split-phase. Quatro would be indicated if you need more power than that.
