SMA Sunny Boy inverters are the most widely used grid-tie PV inverters in the world. SMA inverters are available in sizes from 700 watts to 7000 watts, making them ideal for a wide range of applications from small residential systems to very large 3-phase industrial systems.

All SMA inverters come standard with built-in LCD digital monitors that display instantaneous power output, energy delivered during the current day and the total energy produced since installation. The SB4000 is auto-sensing for uses 240 VAC and 208 VAC applications.

SMA offers a wide range of accessories for communications and monitoring of the system. The SB 4000 comes with a DC disconnect switch and an integrated fused series string combiner that connects to the bottom of the inverter. The disconnect switches are housed in a NEMA 3R enclosure. All electronic components are in a sealed compartment.

The SB 4000 is housed in a completely sealed stainless steel enclosure. Outdoor installation is recommended for the sealed inverters so natural air-flow can cool the heat-sink.

This inverter is compliant with UL 1741, UL 1998, IEEE-929, IEEE-1547, FCC Part 15 A & B. SMA inverters have a standard 10-year warranty.
