Send your device list
If a device is not in the library yet, we build the template for free as soon as we have the register data.
Use cases
- Show solar power, grid import and export and battery charge on one ModbusCloud dashboard per site.
- Send an email when a fault register is not zero or the system state changes to a fault.
- Track daily solar generation and grid import in the history to compare months and seasons.
- Switch the energy storage mode from self use to time of use from the portal for a planned tariff.
- Set an alarm when battery state of health drops below a threshold you choose.
Installation
Connect RS485 A and B from the ModbusCloud Gateway to the communication port of the inverter, with a 120 ohm resistor at both ends of the bus.
In the inverter menu, check the Modbus address (1 by default) and the baud rate (9600).
In ModbusCloud, add a Modbus RTU device with address 1, 9600 baud, 8N1, and import the ZCS Azzurro 3PH HYD ZSS template.
Check that PV power, grid power and battery state of charge come in and match the inverter display.
Things to watch for
The inverter does not answer on the RS485 bus. What should I check?
Check that A and B are not swapped, that the address in the inverter menu matches the one in ModbusCloud and that both sides use 9600 baud 8N1. Fit a 120 ohm resistor at both ends of a longer bus. A data logger on the same port can block the bus.
Why does power show 0.05 instead of 50 watts?
Most power values come in kilowatts with two decimals, so 0.05 means 50 W. Battery power total and PV power total use one decimal in kilowatts. Reactive and apparent power use the same scaling and are probably in kvar and kVA.
How do I change the energy storage mode or the feed-in limit?
Write the new value to Energy Storage Mode or to the Feed-In registers. The inverter expects settings that belong together, such as the feed-in mode and maximum power or the three passive mode powers, in one write. Read the current values first and change one setting at a time.
Battery values show zero for battery inputs 2 to 8.
Only the battery inputs that are connected and configured return values. With one battery stack, its values are under battery 1 and the totals; the other inputs stay at zero.
