Accessory for central inverters

  • Nanocrystalline amorphous glassmetal reduces the no-load losses
  • Significant reduction of operational costs
  • Low standby-costs
Matching products

Besides high-quality modules, inverters and assembly material installed in a PV plant, the choice of the medium range transformer has a significant influence on the efficiency of the whole system.

Type series SBHL 15

Medium range transformers of the type series SBHL 15 from Eaglerise Electric & Electronic Co. Ltd/ Sunrise Power Transformers GmbH are among the most efficient inverters available today. They stand out due to a very high efficiency factor and extremely low no-load losses. By the use of nanocrystalline amorphous glassmetal the no-load losses are lowered which reduces the operational costs of a photovoltaic system significantly.

Types series S11

Besides the high-efficiency transformers the following optimised standard types are available for the installation in PV plants.
