SMA SI 4548-US Sunny Island 4500W / 48VDC Inverter

SMA SI 4548-US Sunny Island 4500W Inverter

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. 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.

Features of the SMA SI 4548-US Sunny Island 4500W Inverter:

Flexible

  • For systems from 2 to 100 kW
  • Single, 120/240V split-phase and three-phase operation, connectable in parallel and modularly expandable

Simple

  • Easy commissioning with the "Quick Configuration Guide"
  • Complete off-grid management
  • Excellent for grid-tied battery back up

Efficient

  • Max. efficiency: 96 percent
  • CEC of 94.5 %
  • Intelligent battery management for longer battery lifespan
  • State of charge calculation

Durable

  • Extreme overload capability
  • OptiCool
  • 5-year SMA warranty
