Designed for rough ambient conditions for stand alone or grid back up operation. Rated to give a power output of 3.0kW or 4.4kW for 30 min.
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.
Inverters are used with the Sunny Island Remote Control which gives a single point of operation. One Remote Control is required per cluster of up to three inverters and includes integrated MMC/SD memory card reader to enable updates, transferring of parameter settings, for storing error/events lists, or data logging.
In single-phase systems only one SI3.0M-11 or SI4.4M-11 can be used. Three-phase systems can be achieved using a cluster of three SI3.0M-11 or SI4.4M-11 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
