Sunny Boy Grid-Tie Inverters

Sunny Boy Grid-Tie Inverters

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 SB700 and 1800 have 120 VAC output. The SB3000 and SB4000 are auto-sensing for use on 240 VAC and 208 VAC appli- cations. The SB 5000, 6000 and 7000 can be used in 208, 240 and 277 VAC applications. SMA offers a wide range of accessories for communications and monitoring of the system. The SB 3000 and 4000 come with a DC disconnect switch and the SB 5000, 6000, and 7000 come with an AC/DC disconnect switch, each with an integrated fused series string combiner that connects to the bottom of the inverter. The dis- connect switches are housed in a NEMA 3R enclosure. All electronic components are in a sealed compartment.

The SB 700 is housed in a completely sealed stainless steel enclosure. Outdoor instal- lation is recommended for the sealed inverters so natural air-flow can cool the heat-sink. The table on page 9 shows a typical module string size for many PV module brands that can be used with each inverter. This number can vary depending on maximum and minimum temperatures in the location where the system is installed. For more details, consult us or visit SMA America to use SMA's string-sizing software.

All inverters are compliant with UL 1741, UL 1998, IEEE-929, IEEE-1547, FCC Part 15 A & B. The new SMA inverters now have a standard 10-year warranty.
