We work in Congo, Africa, and receive 3 phase 220Vac from the grid. However, due to the constant and lengthy power outages, I'd like to run my single phase 220Vac Multiplus off of a backup generator. Unfortunately, the generator provides "split phase" 220Vac as what you would find at the outlet of a drier in the U.S. The inverter refuses to recognize the input and has a bottom input threshold of 180Vac, blocking me from using it in its current configuration or from using one 110Vac leg of the generator output to power it. Here in a remote jungle village, we always have to improvise, so I am looking for a solution, understanding that it might not follow normal practice or meet "code". Thanks for the help
