Application Scenario:Split-Phase Solar Energy Monitoring
The PC341 enables real-time monitoring in split-phase (120/240V) systems, commonly used in North American homes.
It can track solar inverter output, grid consumption, and multiple branch circuits using CT clamps, providing clear visibility of energy flow for residential energy management.
