SMA: Sunny Island Off-Grid Inverters
SMA has released its new Sunny Island 4548-US and 6048-US off-grid solar inverters for the North American market. Expanding upon the proven technology of the Sunny Island 5048-US, these devices reach a new maximum efficiency of 96 percent and CEC-weighted efficiencies up to 94.5 percent, as well as up to a 20 percent increase in power output for the Sunny Island 6048-US. The Sunny Island 4548-US and 6048-US can be paired with SMA’s Multicluster Box, making them ideal for three through 100 kW off-grid PV systems.
Additional features of the Sunny Island 4548-US and 6048-US include intelligent battery management for maximum battery life, state-of-charge calculation and AC and DC coupling. Applicable for single- and three-phase PV systems, they also offer parallel connection and modular expansion. Their robust surge capability is ideal for starting large loads and their durability is enhanced with SMA’s patented OptiCool active temperature management system.
Installers can utilize SMA’s advanced data collection and communication devices such as the Sunny WebBox data logger to help track system performance. Data can be transmitted by cable to the SMA Sunny Portal, the world’s largest Web platform for monitoring, managing and presenting photovoltaic systems.
SMA’s Multicluster Box for the Sunny Island 4548-US and 6048-US is the ideal solution for the easy installation of island and hybrid systems up to 100 kW. It allows two, three or four three-phase clusters, each consisting of three Sunny Island inverters, to be connected in parallel. Pre-wired and equipped with a main connection for PV or wind energy systems, the Multicluster Box includes all communication cables necessary for installation.
