Modbus TCP
Kostal Plenticore PV-Inverter
Kostal
Overview
The Kostal Plenticore is a three-phase hybrid PV inverter used in residential and commercial solar installations. This Modbus TCP template reads per-phase AC measurements across L1, L2, and L3, covering voltage, current, and active power for each phase, plus grid frequency, total active power, and the inverter's maximum apparent power rating. Together these registers give you a complete picture of AC output performance in real time. Connecting the Kostal Plenticore to ModbusCloud Gateway lets installers and asset managers track generation accurately without manual site visits.
Use cases
- Monitor total active power output to verify the Kostal Plenticore is delivering expected generation at any time of day.
- Track per-phase active power on L1, L2, and L3 to detect phase imbalances caused by uneven string loading.
- Alert on grid frequency deviations outside the nominal 50 Hz band to catch grid instability events early.
- Compare per-phase voltages across L1, L2, and L3 to identify grid supply asymmetry at the installation site.
