The MITSUBISHI ELECTRIC watt-hour meter with MODBUS communication and bidirectional metering measures both energy imported from the grid and energy exported back to it. Readings for each direction are transmitted over MODBUS to monitoring systems. It is used at sites with solar generation, cogeneration or regenerative equipment where net energy flow must be tracked.
