Content and structure of the section. The sunny island 5048 sma technologie ag page 12 si5048 11ee4206 technical description configuration. The sunny island inverters are capable of forming an ac grid this sine wave can be used as an interface for pv inverters to synchronize and feed power into the system which is used for supplying loads and recharging batteries.
The pair is out of sync to allow for 120 and 240 volt ac. The switched current of the relays k7 and k8 is a maximum of 5 a at 230 v ac. The new sma sunny island 4548 us and 6048 us inverters are based on the proven off grid technology in the sunny island 5048 us but now feature 20 percent more power output. The easy to understand menu navigation allows quick access to all important data even while the system is running. The maximum output power of the ac sources in a stand alone grid must be observed see the sunny island inverter installation manual. A detailed limit curve is shown in chapter 18.
