Sunny Inverters

SMA Solar Technology is a global leader in the development, production and sales of PV inverters and offers innovative key technologies for PV power supply solutions.

SMA has an extensive range of products, offering suitable inverters for all module types and plant sizes from small residential systems up to largescale plants, grid-connected installations as well as standalone and backup systems. Plant monitoring and visualization products, as well as energy management solutions, complete the portfolio.

PV Inverters: SMA PV Inverters are transformerless design with two MPP trackers that converts the DC power of the PV array to grid compliant AC power and feeds it into the utility grid. The Sunny Tripower are three phase inverters, developed for mid to large-scale commercial and industrial plants.

Battery Inverters: The Sunny Island Inverters are battery inverters suitable for off-grid or battery backup applications. Together with the battery array, Sunny Island forms an independent AC power grid accessible to both energy suppliers and consumers.

SMA offers various monitoring and control accessories including:

  • The SMA Energy Meter for optimal energy monitoring, effective load, and battery management.
  • The Sunny Home Manager allows the user to identify and optimize energy consumption habits by monitoring and analyzing all energy flows in the home.
  • The Sunny Remote Control unit for control and visualization unit for Sunny Island Systems allowing remote monitoring and commissioning of the inverters
  • The SMA Cluster Controller functions as the central communication unit for system monitoring, recording data, and controlling large-scale PV plants.

The SMA range of inverters are proven and dependable designs using the latest technology to give exceptional levels of performance, economy and reliability. They are market-leading products and are suitable for a wide range of applications.
