SMA Revenue Grade Meter Kit is a revenue-grade energy meter designed for monitoring Sunny Boy inverter production with a 0.5% degree of accuracy. Its compact size and plug-and-play design allow it to be easily and quickly installed inside the Sunny Boy inverter. It collects a wide array of energy data which is either locally in the inverter or uploaded to the Sunny Portal allowing both system installers and owners to efficiently manage solar assets. It is designed to operate in unison with the SMA RS485 Module.
