I live off grid and have a European Multiplus 230V Inverter paired with an Autotransformer that gives me two 120V legs (I'm in the US). This allows me to use 120VAC in the house and also power some devices that require 240VAC split-phase.
I have a backup generator which outputs split-phase 240VAC. If I want to connect my generator to the Multiplus AC Input, can I simply use one hot wire from my generator as the line and the other hot as the neutral?
Any help appreciated.
Yes, that connection will work and you'd ignore the neutral from the generator.
You may need to adjust some voltages. The generator will output 240 volts and will pass through the Multi to the autotransformer. If that is configured to take in 230 volts and output 120/240 split phase, your voltages running on generator will be high: roughly 125 volts per leg, 250 volts across the legs.
What you should probably do is set the autotransformer for 1:1 and set the Multi to output 240 volts rather than 230.
Thank you, that was my hunch but I wanted to get some external validation.
Yes I'll set the Multi to output 240 instead of 230. I'm unclear on setting the autotransformer for 1:1, can you expand a little more on what that means?
Much appreciated
