IVY Metering solar PV solutions include solar PV monitor(AC&DC energy meters), relay, and RCMU sensor, etc. A solar net meter, also known as a net energy meter, is a bi-directional meter that measures the flow of electricity in both directions, allowing you to credit excess electricity generated by your solar panels back to the grid. This credit can then be used to offset future electricity consumption when your solar panels aren't producing enough power.


The EM513082 is a reliable Class B MID-certified three-phase energy meter providing precise measurement of both active and reactive energy. With a voltage rating of 3x230/400V and a current range of 5(100)A, this meter supports both forward and reverse energy measurement, ensuring comprehensive monitoring. Compliant with EN50470-1/3 requirements, it offers versatile RS485 communication, seamlessly supporting both the widely adopted Modbus protocol and the DLT645 protocol, enabling easy integration into various monitoring systems. The inclusion of a built-in battery ensures data integrity during power interruptions, and the integrated tariff function allows for multi-rate energy billing. Its compact design allows for simple DIN rail mounting.

In PV systems, the integration of RCDs or RCMUs into solar inverters is often required by regulations to prevent ground faults. For non-isolated grid-tied solar inverters, the embedded RCD/RCMU must detect continuous residual currents and sudden changes in residual current as per standards like DIN/VDE 0126-1-1 and EN/IEC 62109-2.


The residual current detection functionality in solar inverters is crucial for safeguarding the PV array side. However, it cannot replace external RCDs in the AC circuit, as the internal RCD/RCMU does not protect the segment between the power source and the solar inverter. The need for external RCDs—whether AC-type, A-type, or B-type—depends on the inverter design, particularly its ability to prevent DC residual currents from flowing into the AC side.
