PA300 solar inverter energy meter three phase power meter use for inverter solar 41st Harmonic THD
power quality analyzer
The meter measures the instantaneous voltage, current, power and energy of a 3-phase system, or circuit, or load.
The power data is transmitted to the inverter or other monitoring device. Inverters use data to selfmanage grid inputs from solar or battery power sources, and to control external devices such as relays.
Monitoring devices typically send the data on to a remote energy management system.
The PA300 uses non-intrusive, clip-on, "split core” type CTs (current transformers). PA300 variants and different CTs are available for high current applications. Ensure you have the correct device and CTs for your application. The installation process is similar for all PA300 and CT variants.
This manual demonstrates instalation using 16mm/100A CTs, but other CTs are installed in a similar manner, making allowance for the size variation.
