SMA America Debuts Slim-Line Sunny Boy Photovoltaic Inverter


Rocklin, Calif.-based SMA America says it is now shipping the Sunny Boy HF-US line of high-frequency residential solar inverters. The UL-certified Sunny Boy 2000HF-US, 2500HF-US and 3000HF-US grid-tied inverters feature a slim enclosure, reduced weight, modern graphic display and industry-leading efficiencies, according to the company.

Sunny Boy HF models are well suited for 2 kW to 3 kW solar arrays and offer CEC-weighted efficiencies of 96.5% (Sunny Boy 2500HF-US and 3000HF-US) and 97% (Sunny Boy 2000HF-US). They measure 14 inches across and feature a nearly 45% reduction in weight over previous models, making them easier to handle and allowing them to be mounted in between wall studs.

Sunny Boy HF inverters also contain a plug-in grounding system that allows for quick field configurability for modules requiring positive grounding, the company adds. The Sunny Boy HF's wide input DC voltage ranges of 175 V to 600 V (Sunny Boy 2000HF-US) and 220 V to 600 V (Sunny Boy 2500HF-US and 3000HF-US) provide added system design flexibility and improved performance for smaller arrays.
