Atmoce AC Battery and Module-Inverter

Use cases

• Monitor real-time PV power output and battery state of charge on a cloud dashboard for each customer site.
• Create alerts when energy storage SOC drops below a defined threshold during peak tariff hours.
• Remotely configure forced charging schedules to take advantage of low electricity rates overnight.
• Track cumulative PV generation over time to verify system performance against design expectations.
• Regulate active power output remotely to comply with grid feed-in limitations set by the utility.
• Manage multiple Atmoce inverter and battery systems across different sites from a single platform.

Installation

1. 1Connect the Modbus RTU wiring (A and B terminals) from the Atmoce module-inverter to the RS485 port on your ModbusCloud gateway (MCG or MLP series).
2. 2Configure the Modbus RTU settings on the gateway to 19200 baud rate with odd parity (parity 1) and set the correct slave address matching the inverter configuration.
3. 3Verify that Modbus RTU communication is enabled on the Atmoce inverter, checking the device manual for the relevant setting menu.
4. 4Import the Atmoce AC Battery and Module-Inverter template from the ModbusCloud template library into your project.
5. 5Confirm that register data is arriving correctly by checking live values in the ModbusCloud dashboard, paying attention to uint32 and int32 register alignment starting at address 60027.
6. 6Test write functionality by sending a minor control command, such as adjusting the active power percentage, and verifying the inverter responds as expected.
