Maximizing the energy from Thin Film

Maximizing the power from the sun

The SunMaster IS range maximizes the energy production of Thin Film installations. The modular concept simplifies installation and ensures easy maintenance, resulting in reduced overall Cost of Ownership. Each power module incorporates the proven technology of Mastervolt. The power modules have been designed to provide high efficiency and extremely low losses, resulting in a very high annual yield.

Flexible design

  • Compatible with any type of solar module: CIGS, CdTe, amorphous silicon, mono- and poly-silicon and back contact technology.
  • Integrated HF transformer provides galvanic isolation, no grounding kit needed.

High yield

  • 100% power, up to 45 °C ambient temperature.
  • High efficiency over full power range.
  • A low self consumption ensures early start-up and late shutdown.
  • Adaptive cooling technology.
  • Three highly efficient MPP trackers generate maximum yield from the solar panels, even at low light conditions.

Easy & safe installation

  • Ventilation from bottom to top: They can be placed side by side.
  • Wall mounted enclosure.
  • Segnential mounting of backbone, power modules and front cover.
  • Power modules are equipped with 4 mm² Multi Contact connectors and cables.
  • Integrated DC switch and over voltage protection (optional connection kits).


  • Standard 5 years warranty, 10 or 20 years as option.
  • Proven Mastervolt concept.
  • High cooling efficiency extends operating life and increases yield.
  • Replaceable air filter.

Ordering procedure

Various country specific models are available. Isolation monitoring may be disabled for functional grounding purposes. Please contact Mastervolt for applicable article numbers.
