Sunny Tripower CORE1 Accessories

Modbus Protocol Interface
Modbus Protocol Interface
With the Modbus protocol interface, SMA makes flexible integration of inverters possible. Through the use of this well-known industry standard, you can integrate SMA Sunny Tripower CORE1 inverters into your systems without having to follow the SMA-specific inverter protocol.
SMA Cluster Controller
SMA Cluster Controller
Combined with highly efficient SMA Sunny Tripower Core1 inverters, the SMA Cluster Controller is the perfect system solution for decentralized large-scale PV power plants.
RS485 Data Interface
RS485 Data Interface
The ideal solution for the expansion of existing PV systems that already use RS485 communication. The RS485 interface can be retrofitted and guarantees the proven, cable-based SMA fieldbus communication via RS485 for simple connection to a data logger with a cable length of up to 1,200 meters.
Sensor Module MD.SEN-US-40
Sensor Module
The MD.SEN-US-40 sensor module allows you to record environmental data such as solar irradiation and cell temperature to analyze CORE1 inverter system performance. This means that any PV system malfunctions can be detected quickly and yield loss minimized. The SMA Sensor Module allows you to connect sensors that measure ambient temperature or wind speed and also provides a simple display for an S0 energy meter.
