Sermatec SMT-10K-TL-LV Hybrid Inverter (pv)
Sermatec
Overview
The Sermatec SMT-10K-TL-LV is a low-voltage hybrid inverter for residential and small commercial PV installations, combining solar generation, battery storage, and grid connection in one unit. This Modbus TCP template reads two PV string power registers, power_a and power_b, corresponding to the inverter's dual MPPT inputs. Connecting the SMT-10K-TL-LV to ModbusCloud Gateway gives you a live per-string view of solar generation that you can log, chart, and alert on from the portal.
Use cases
- Monitor PV string A and string B power in real time to verify both MPPT channels are producing.
- Compare power_a and power_b values to detect imbalance between the two PV strings over a season.
- Alert on a sudden drop in either string's power to catch shading, soiling, or partial-string failures quickly.
- Log per-string generation data across multiple Sermatec sites in one ModbusCloud multi-site overview.
- Verify that both strings recover to expected output after cloudy periods or maintenance work on the array.
