PA120 Solar Inverter Energy Meter Two Independent Phases Power Meter 41st Harmonic THD Power Quality Analyzer
Overview:
The meter measures the instantaneous voltage, current, power, and energy of a **2 independent phases system**, circuit, or load.The power data is transmitted to the inverter or other monitoring devices. Inverters use this data to self-manage grid inputs from solar or battery power sources and to control external devices such as relays. Monitoring devices typically send the data to a remote energy management system.
The PA120 uses non-intrusive, clip-on, "split core" type CTs (current transformers). **PA120 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 **PA120 models** and CT variants. This manual demonstrates installation using 16mm/100 A CTs, but other CTs are installed in a similar manner.
Features:
● Bi-directional energy of up to two lines.
● Current measurements up to 400A with other CTs.
● Open-core CT & Rogowski cil can be selected.
● Voltage measurement up to 275V.
● True RMS power measurements including Volt, Amp, Watts, Var, VA, Power Factor, Frequency.
● Hold a rolling 60 second min/max/avg value for each measurement.
● Measure and process data for grid quality, THD up to 41 harmonics.
● Record a Frequency Control Auxiliary Service (FCAS) event when a frequency excursion is detected.
● Operate 12VDC/2W power supply to connected communications gateway.
● Relay control for external remote control.
● RS485 communication Modbus RTU protocol.
● 1-DIN size module for easy installation.
● Accuracy class 1 according to IEC62053-21.
● Remote firmware upgrades possible.
