Senergy Hybrid Inverter (pv)
The Senergy Hybrid Inverter is a residential and light-commercial PV inverter with integrated energy storage support, deployed in rooftop solar installations. This ModbusCloud template connects via Modbus RTU over RS485 and reads two key production registers from the Hybrid Inverter and Alfred 10: instantaneous PV power output and cumulative PV energy yield. With these two registers logged continuously in your portal, you can track real-time solar generation, build long-term yield histories, and catch output degradation before it affects your energy bill.

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
- Monitor real-time PV power output to confirm the Senergy Hybrid Inverter is producing at expected levels during peak sun hours.
- Track cumulative PV energy yield over months to verify annual generation matches the system design estimate.
- Alert on sustained drops in PV power output to detect shading, soiling, or inverter faults on the Alfred 10.
- Compare daily energy totals across multiple Senergy installations in the ModbusCloud multi-site overview.
- Report monthly PV generation figures to building owners or grid operators using historical data from the portal.
Installation
Enable Modbus RTU communication on the Senergy Hybrid Inverter under the communication or Modbus section in the device settings, and note the configured unit ID (default is typically 1).
Wire the RS485 A and B terminals of the inverter to the RS485 port of the ModbusCloud Gateway using a twisted-pair cable, keeping the run under 1000 m and terminating with a 120-ohm resistor if the inverter is at the end of the bus.
In the ModbusCloud portal, add the Gateway, create a new device, import the Senergy Hybrid Inverter (pv) template, and enter the unit ID that matches the inverter configuration.
After saving, open the live register view and verify that the power register at address 4168 returns a plausible watt value during daylight; if it reads zero at midday, recheck the RS485 wiring polarity and unit ID.
Things to watch for
The power register always reads zero even in full sun. Why?
Check that the RS485 A and B wires are not swapped. Senergy inverters will not respond correctly if polarity is reversed. Also confirm the unit ID in the portal matches the ID set on the inverter, and that the baud rate on both sides is identical, typically 9600 baud.
Values appear but seem far too high or too low. What is wrong?
The power register at address 4168 returns a uint32 raw value. Confirm that no additional scaling factor is being applied in the portal. The register has no unit annotation in this template, so verify against the device display to determine if the firmware applies a fixed divisor before treating the value as watts.
The Gateway connects but register reads time out intermittently. What now?
Intermittent timeouts on RS485 often indicate missing bus termination or an overlong cable run. Add a 120-ohm termination resistor at the far end of the RS485 bus. Also ensure no other device is polling the same unit ID simultaneously, as bus contention will cause timeouts.
The energy register at address 4129 does not increase over time. Is it broken?
The energy register is cumulative and updates at the inverter's internal logging interval, which may be slower than the portal polling rate. Confirm the inverter is actively converting power (check the power register first) and allow several minutes before concluding the counter is frozen.
