High frequency synchronization and power sampling card(synchronization and sampling card, SS card)
The synchronization and sampling card is used to collect instantaneous values of voltage, current, etc. of devices that are not directly connected to Smarten Power 150, and to provide conventional communication bus and high-frequency synchronization signals when multiple converter are connected in parallel with a common DC link.
Interfaces
Interface overview
Among these sockets, the white sockets are used for parallel cables. The parallel operation cables are included in the package and can be directly inserted into the corresponding sockets when needed.
The green sockets are for external uses, and users need to connect them by themselves.
H12 is used to connect to the 120Ω communication matching resistor. The resistor is already onboard, by shorting the terminals with jumpers, the resistor is implemented.

Parallel Communication
Depending on the application configuration, Smarten Power 150 supports two communication architectures:
- Single machine independent use, or multiple machines connected in parallel on the AC side but not on the DC bus. In this case, Smarten Hub Lite needs to be inserted into the module
- Multiple modules form a single machine, such as multiple converters connected in parallel on a common DC link. In this case, an external Smarten Hub is required
Smarten Hub Lite
Smarten Hub Lite is located near the synchronous sampling board. It is used to provide the following functions:
- Web UI access
- Modbus TCP communication
- IO function

Smarten Hub
Smarten Hub is a control unit independent of Smarten Power 150.
Smarten Hub provides the following functions:
- Multiple external signal connection interfaces, such as RS-485, CAN bus, Ethernet communication, and multiple configurable dry contact input and output
- If there is a higher-level control unit, such as the upper-level energy management system (EMS), it will serve as the total input for information transmission to the upper-level control unit, and will coordinate, control, and feedback all modules connected in parallel on the CAN bus of Smarten Hub.
- Smarten Hub has a built-in Web server, and the Web UI can be accessed through the web page
- It has software scalability to achieve more advanced functions
