Solar-Log® Revenue Grade Metering

Solar-Log 2050

Solar-Log 2050

(Solar-Log® data logger and required CTs sold separately)

The Solar-Log 2050 is a revenue grade metering assembly designed for commercial and industrial scale solar plants. The assembly provides highly accurate solar plant production metering required by many PPAs, financing companies, and performance-based incentive programs (PBI/SREC). When combined with a Solar-Log® data logger, the assembly offers performance data from inverter direct monitoring and optional power control.

Packaged in an indoor/outdoor enclosure, the Solar-Log 2050 assembly includes a revenue grade meter, power supply, fusing blocks, shorting blocks, data connection blocks, and a DIN rail for mounting a Solar-Log® data logger.

Automatic performance-based incentive reporting (PBI/SREC) is available with the use of the Solar-Log 2050 with a Solar-Log® data logger, plus a Solar-Log WEB Enerest™ XL subscription.
