Powerdog
Overview
The Powerdog is a PV monitoring and energy management data logger made by ecodata GmbH. Installed at the site, it aggregates data from connected inverters and exposes values over Modbus TCP. This template reads the instantaneous PV production power from holding register 40002, giving your ModbusCloud portal a live view of solar generation output. With this single register polled by the ModbusCloud Gateway, you can trend production, trigger alerts on unexpected drops, and verify that the installation is generating as expected.
Use cases
- Monitor live PV production power in the ModbusCloud portal to verify daytime generation is within expected range.
- Alert on a sustained drop in the power register during daylight hours to detect inverter faults early.
- Track PV output over multiple days to compare production against weather data or irradiance baselines.
- Report on daily peak power values to support O&M reviews and client reporting for the site owner.
