The 'energy measuring sensor' is used to record the solar energy converted in the PV inverter and then transmit it to the room manager with 'energy management function' for display. This device type is used for outputs of 3-3680W. Current, voltage, active power and electrical energy are determined. The 'energy measuring sensor' is preferably connected to the feed-in point in the electrical system. The device is installed in the switch, junction or installation box. The device is not calibrated and therefore not suitable for billing purposes!
