SMA has released its new Sunny Island 4548-US and 6048-US off-grid solar inverters for the North American market.
The company says the new devices reach a maximum efficiency of 96% and CEC-weighted efficiencies of up to 94.5%, as well as increase power output by up to 20%, in the case of the Sunny Island 6048-US.
The Sunny Island 4548-US and 6048-US can be paired with SMA's Multicluster Box, making them suitable for off-grid PV systems up to 100 kW. Additional features of the Sunny Island 4548-US and 6048-US include intelligent battery management, state-of-charge calculation, and AC and DC coupling.
Applicable for single- and three-phase PV systems, the new inverters also offer parallel connection and modular expansion, SMA adds.
