(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 Solar-Log 2050 can be used for production metering or consumption monitoring. When combined with a Solar-Log® data logger, the assembly can offer performance data from inverter direct monitoring, power control, and automatic performance-based incentive reporting with purchase of a Solar-Log WEB Enerest™ XL subscription. The Solar-Log® communicates with an RS485 or pulsing meter to deliver high accuracy metering required by many plant owners, PPAs, and financing agreements for reporting, accounting, or billing purposes. The Solar-Log 2050 offers many customizable solutions to meet the needs of fleet managers, solar PV installers, reporting agencies, utilities, and end-users.
