An energy meter can be installed for acquiring high precision readings and enabling measurement to be easily read on a monitoring center. Installed externally or embedded into an inverter, there are different meter connection options available for choice upon request. The solar meter can be directly embedded into a single PV inverter without RGM. When connecting with an inverter equipped with a built-in RGM (Revenue Grade Meter), the solar power meter can be externally installed on the same bus as the RGM.
