The Sunny Island 3324/4248 is the system manager of a stand-alone power sup¬ply. Its service life of over 20 years makes it a future-proof investment. The Sunny Island 3324/4248 also works reliably under extreme ambient conditions, such as high temperatures or excessive dust. The AC coupling developed by SMA provides maximum flexibility in expanding the system and reduces installation efforts and costs. Other AC sources can be easily connected to the AC bus and therefore substan¬tially increase performance an the AC side. This allows batteries and generators to be dimensioned smaller. The integrated smooth startup mode allows all loads to be started safely.

  • Suitable for systems from 2 kW to 5.4 kW
  • The only inverter with AC coupling for all energy sources
  • Fully automatic uninterrupted Operation
  • Robust and reliable
  • Excellent overload characteristics
  • Easy installation
  • Long battery service life thanks to Optimum battery management system
  • Compatible with Sunny Family products
