SMA SB3.0-US-40 3000 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
