Solar-Log 10 Power Meter

Solar-Log™ PRO380-Mod-CT


Measure, Record, and Display the Amount of Self-Consumed Power

Solar-Log 10 Power Meter

Maximize plant performance and confirm net metering bills by automatically calculating the amount of consumed grid power using the Solar-Log 10 Meter. This bidirectional power meter connects to Solar-Log® data loggers via RS485 and allows plant owners to monitor total building-load by measuring power inside the main distribution panel at the utility connection. The meter includes 2 current transformers for measuring the current and phase voltage.

The Solar-Log 10 is made in the USA.


The Solar-Log 10 Meter connects to Solar-Log® Data Logger or the Solar-Log 370 via RS485. The included
200A CTs connect inside the main distribution panel at the utility connection
