ZCS Azzurro HYD 10000 ZSS/HYD 20000 ZSS - Three-Phase Hybrid Inverter - Modbus

Installation

1. 1Install the ZSM-ETH-EXT or ZSM-WIFI-EXT stick logger on the Azzurro inverter and connect it to the local network.
2. 2Verify that the stick logger has obtained an IP address and is reachable from the ModbusCloud gateway (MCG or MLP series).
3. 3Connect the ModbusCloud gateway to the same local network as the stick logger, either via Ethernet or Wi-Fi depending on the gateway model.
4. 4Import the Azzurro HYD 10000 ZSS / HYD 20000 ZSS template in the ModbusCloud platform and set the target IP to the stick logger's address with TCP port 8899.
5. 5Confirm that live register values appear on the ModbusCloud dashboard, checking PV power, battery SOC, and grid energy readings for plausibility.

Things to watch for

01

I cannot reach the stick logger on port 8899. What should I check?

Ensure the stick logger is powered and connected to the local network. Verify its IP address in your router's DHCP table. Check that no firewall rules block TCP port 8899 between the ModbusCloud gateway and the stick logger.

02

PV power values seem too low compared to actual production. Why?

PV power registers are reported in kilowatts, not watts. Confirm that the template scaling is applied correctly. If you see values like 5.2, that represents 5.2 kW.

03

Energy total registers show incorrect or very large numbers. What is wrong?

Energy totals use uint32 format spanning two consecutive Modbus addresses. Make sure the template is imported without manual register modifications, as splitting or reordering these addresses will produce wrong values.

04

Can I use this template to control or configure the inverter remotely?

No. This template is read-only and does not include write registers. All inverter configuration must be done through the manufacturer's own tools or the inverter display.
