solarone PM3

Three-phase power meter with integrated logger shows energy flow in bigger installations. Can be used to monitor inverter performance in old installations.

Perfect solution for PV plant owners who want to monitor three-phase networks for solar generation and consumption.

PV plant owners get the full functionality of solarone 1000 plus a built-in smart meter to monitor the performance of PV plants and track the efficiency of green energy consumption.

PV park developers use solarone PM3 to solve compatibility issues for PV parks in different regions and countries. All PV parks are visible in one developer dashboard.

Contractors and O&M companies choose solarone PM3 for its capability to show inverter generation data even without being connected to a logger. This is very useful for maintenance – correct generation data is displayed even when the inverter brand is changed.
