SMA Sunny Island 4.4M-13

Designed for rough ambient conditions for stand alone or grid back up operation. Rated to give a power output of 4.4kW for 30 min.

  • Compatible with many well-known brands of lithium-ion battery and all lead-acid batteries
  • Includes integrated Wi-Fi and Ethernet interfaces
  • Allows set-up using laptop or Smart device (phone or tablet)
  • IP54 protection to allow outdoor installation if required.
  • High efficiency (>95%);
  • Low standby & idle consumption (25W/4W);
  • Operating temperature range of -25 to +60 deg C.
  • OptiCool system ensures high power in high temperatures by cooling the encapsulated transformer but keeping air ventilation away from coated circuit boards & electronics to ensure high protection for humid or salty atmospheres.
  • Includes two free programmable relays per unit to enable load shedding or other use and timers to enable daily, weekly, or monthly functions.

In single-phase systems only one SI4.4M-13 can be used. Three-phase systems can be achieved using a cluster of three SI4.4M-13 inverters, multi-cluster systems are not possible with these inverters.

For larger single-phase or multi-cluster 3-phase systems please see the Sunny Island 6.0H/8.0H below.

SMA Sunny Island MultiCluster Boxes

Install large off-grid systems with minimum effort. The Multicluster-Boxes for the Sunny Island inverters are the ideal solution for the easy installation of island and hybrid systems from 30 up to 300 kW. They include integrated generator and load shedding contactors for AC distribution. For an example of Multi-cluster boxes in use see Isle of Eigg project.

The SI-MCBOX-12.3-20 also allows connection of the grid in addition to a generator for use in both off-grid systems and battery-backup systems.

See optional SMA Sunny Island Multicluster Grid Connect Boxes.
