MODBUS PROTOCOL INTERFACE
The established protocol for easy integration of SMA inverters
With the Modbus protocol interface, SMA makes the flexible integration of inverters possible. The benefits are obvious. Through the use of this well-known, public industry standard, other providers can integrate SMA devices into their systems without having to follow the SMA-specific inverter protocol. System data is transferred via this standardized protocol for further processing and can, as such, be flexibly integrated into any system regardless of the manufacturer. The importance for system planning: You can use SMA inverters in your preferred standard system at any time without having to take manufacturer specifics into account. Direct inverter integration into control room systems or the connection of inverters in building automation systems are both ideal applications.
