I am needing some help with understanding my situation and what to do with my current scenario. I have 2 sets of 12 panels hooked up to 3- 220v inverters hooked up in series, model number WVC-1200. I have run 4 wires to the panels from the house 240’ to the array that I installed on the side of the hill. These inverters state that they are 220v but they only have three wires which are 1 hot, 1 neutral, and a ground. The diagram listed on the installation does not explain how to hook up 220v using only one hot wire. I am wondering, if inverters convert the neutral to hot when configured in 220v mode. I feel like I have no support getting these hooked up and I am nearing completion but I need very clear instructions to how to hook these up. Please be good news. Thank you for any assistance.
