I have a non-Victron inverter supplying 240 non-split phase to the AT. There is polarity indicated on the ground relay input (+ & -), so it appears to take more than a jumper. What input is required to close the circuit between output Neutral & Ground?
I have same question. I want to use 2 growatt spf5000es transformers in parallel single phase 240VAC, using a victron 100amp autotransformer to get 120VAC legs, but when switching to shore power, autotransformer is not needed, I don't know how to wire this.
I really wish somebody would have answered this. This is the second thread I have seen so far asking about this issue with no answers provided.
I have similar questions. I'm not even sure if the "Multi" in the data sheet for the AutoTransformer means Multiplus, Multiplus II, or both. Our dealer assured us the AutoTransformer would work for the Multiplus II but I am not sure if that is accurate or not.
We purchased 2 inverters and an AutoTransformer as a solution to run power 500 feet away from the inverters to our cabin. We bought a huge expensive wire to run that power that long distance (https://nassaunationalcable.com/products/250-triplex).
We are now discovering that beyond the power cables, that another wire between the AutoTransformer and the inverters might be required for the inverters to control a relay? If so, what is the voltage of this wire and will we be able to run it the 500 feet to our cabin?
