Modbus RTU
ZCS Azzurro Hybrid Inverter (grid)
ZCS Azzurro
Overview
The ZCS Azzurro Hybrid Inverter is a three-phase hybrid PV inverter for residential and commercial solar-plus-storage installations, produced by Italian manufacturer Zucchetti Centro Sistemi. This ModbusCloud template reads the inverter's grid-side registers over Modbus RTU: grid active power (import and export, signed), per-phase currents on L1, L2, and L3, and a cumulative energy counter. Connecting the ModbusCloud Gateway to the RS485 COM port gives installers and facility managers a continuous, cloud-accessible record of grid interaction without additional metering hardware.
Use cases
- Monitor real-time grid active power to verify whether the Hybrid Inverter is importing or exporting at any moment.
- Track the cumulative energy counter over time to produce monthly grid-consumption reports for building owners.
- Compare L1, L2, and L3 phase currents to detect persistent phase imbalance across the three-phase grid connection.
- Alert on sustained grid import during daylight hours to spot underperforming PV strings or battery issues.
