PRODUCT DESCRIPTION
The new SMA Sunny Island 6048-US inverter is based on the proven off-grid technology in the Sunny Island 5048-US but now features 20 percent more power output. A maximum efficiency of 96 percent ensures peak production, which results in reduced diesel usage and makes a smaller dimensioning of the PV array possible. The new Sunny Island with two different power ratings enable more flexible system sizing. And, with multicluster technology, up to 12 Sunny Islands can be integrated into off-grid power systems up 100 kW in size.
Key Facts and Design Guide:
Grid Types and Options:
- Each Sunny Island is operating with 120Vac. In order to create a 120/240V split-phase system, two Sunny Islands are required, one for each phase. One will be the Master unit, the the Slave unit. Total capacity 12kW/22kWpeak.
- Large split-phase systems can utiliye a total of four Sunny Islands. Two in parallel for each phase. Total capacity 24kW/44kWpeak.
- For a 3-phase 120/208V system, three Sunny Islands are grouped together. Each SI providing one phase. One will be the Master unit and controlls the two other Slave units. Total Capacity 18kW/33kWpeak.
- Larger 3phase systems utilize the SMA Multi-Cluster-Box 12 (MCB-12) that can manage four 3-phase clusters of 3 SI6048-US each for a total of max. 72kW/132kWpeak.
Battery Options:
- Nominal Battery voltage is 48V with a wide operational range of 41V to 63V input, usable for most low voltage battery chemistries.
- Integrated Battery Management System BMS for: Flooded (FLA), Absorbant Glass Matt (AGM), Gelled Electrolyte (GEL) and External Lithium BMS communication.
- A multitude of Lithium Batteries work as Lead Acid drop-in replacements like SimpliPhi and Lithium battery systems that offer CANbus communication with the inverter system like Pylontech US3000C, AmpliPhi, BMZ ESS batteries
Communication and Monitoring:
- SMA SunnyIsland systems utilize the SunnyPortal EnnexOS monitoring platform.
- The master SunnyIsland needs the SI-485PB-NR RS485 communication module
- RS485 will then connect to the SMAÂ ComGateway RS485Â to translate the protocol.
- The SMA Datamanager M or Datamanager M-Lite will then communicate to the EnnexOS platform
- AC coupled SunnyBoy inverters can then be integrated via Ethernet as well.
