Note: Solar-Log data logger and required CTs sold separately

The Solar-Log 2050 is a revenue grade metering assembly designed for commercial and small-utility scale projects to provide accurate solar production information in a convenient, easy-to-install package. When combined with a Solar-Log data logger, the assembly offers performance data from inverter direct monitoring, optional power control, and automatic performance-based incentive reporting with purchase of a Solar-Log WEB Enerest XL subscription.
