The SB700 and 1800 have 120 VAC output. The SB3000 and SB4000 are auto-sensing for use on 240 VAC and 208 VAC applications. 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 disconnect switches are housed in a NEMA 3R enclosure. All electronic components are in a sealed compartment. The SB 700 and SB 1800 are housed in a completely sealed stainless steel enclosure. Outdoor installation is recommended for the sealed inverters so natural air-flow can cool the heatsink.
The display cannot be used if optional remote communication modules are used in the 1800U and 2500U inverters. The 2500U is
available for use on 240 VAC and 208 VAC power. The 6000U can be used on 208, 240 and 277 VAC power. SMA offers a wide range of accessories for communications and monitoring of the system.
The 3800U and 6000U is in a NEMA 3R enclosure but all electronics are in in a sealed compartment. All of the smaller inverters are housed in a completely sealed stainless steel enclosure. Outdoor installation is recommended for the sealed inverters so natural air flow can cool the heatsink. If these inverters are installed inside, the SunnyBreeze on the next page is recommended.
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 your dealer or go to http://www.sma-america.com on the web to use SMA?s string-sizing software. All inverters are compliant with UL 1741, UL 1998, IEEE-929, EEE-1547, FCC Part 15 A & B. The new SMA inverters now have a standard 10-year warranty.
