SMA SB7.7-1SP-US-40 Watt Sunny Boy inverter, the newest range (2017) of residential grid-tie inverters. Designed to operate at 208VAC single-phase or 240VAC split phase, these units were designed specifically for the US market with built-in AFCI and DC disconnects. They have a very wide DC range on their (3) MPPT inputs resulting in earlier startup, later shutdown and ultimate flexibility in array design. These inverters are also fitted with the enhanced SMA OptiTrac™ feature on all inputs mitigating shading issues on the more challenging installs. These units also have “smart-grid” features allowing it to be future proof regardless of utility requirements
• 2000W Secure Power Supply feature.
• Hundreds of stringing configurations.
• Multiple independent MPPTs.
• SMA’s proprietary OptiTrac™ Global Peak shade mitigation technology.
• Diverse application options including on- and off-grid compatibility.
• Direct access via smartphone and utilization of SMA’s Installation Assistant, which minimizes time/labor spent in the field and speeds the path to commissioning.
• Improved communication capabilities that remove the need to install additional equipment.
• Integrated DC disconnect that simplifies onsite logistics and eliminates the need to install a separate disconnect unit, speeding overall installation time.
• Enhanced AFCI technology that improves resistance against false tripping while improving sensitivity in detecting real arcs, which greatly reduces unneeded service calls and increases safety.
• The new Sunny Boy’s two-part enclosure concept that separates the connection unit from the power unit, which allows for simple, expedited servicing.
