Solar Inverters - The Inverters from SMA

Sunny Boy 3000TL, 4000TL and 5000TL with Reactive Power Control

The Heart of every Solar Energy System

Harness the energy of the sun - with a solar inverter from SMA. They convert the direct current generated by the solar module into grid-acceptable alternating current. Thus they form the heart of every solar energy system.

As market leader for solar inverters SMA is setting benchmarks again and again: leading-edge efficiencies of 98 % and new technology ensures maximum yields and the highest user convenience.

We offer you the right device for each application: for all module types, for grid-connection and feeding into stand-alone grids, for small house systems and commercial systems in the Megawatt range.

Solar Power Cairns install SMA Sunny Boy The ideal solution particularly for demanding PV arrays and partially shaded plants: As multi-string devices, the new transformerless Sunny Boy 3000TL, 4000TL and 5000TL models offer maximum planning and realization flexibility. The high DC voltage of 750 V proves to be a cost advantage, since fewer parallel strings are required. In addition, the integrated grid management functions make the devices suitable for universal applications and allow them to actively support the grid. The new wall mounting system further facilitates installation.
