Using a 3-Phase Energy Meter for Solar PV and Grid Consumption in a Split-Phase System
Phases A and B are utilized to monitor the two-phase grid, while phase C is dedicated to monitoring the split-phase inverter output. Ordinarily, two phase channels are needed to measure the inverter's two-phase output. However, due to the balanced nature of the two-phase output, a single phase suffices for measuring the inverter output. This is achieved by internally configuring the meter to double the reading obtained from that single phase.
