SMA Grid-Tie Inverters
Sunny Boy Grid-Tie Inverters
SMASunny 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 SB 700 and 1800 have 120 VAC output. The SB 3000 and SB 4000 are auto-sensing for use on 240 VAC and 208 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 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 is housed in a completely sealed stainless steel enclosure. Outdoor instllation is recommended for the sealed inverters so natural air-flow can cool the heat-sink.

Sunny Island
The Sunny Island inverter can be used for standalone off-grid systems, and they are a great way to add battery backup to an SMA Sunny Boy inverter based grid-conneceted system. UL 1741 Listed.
Grid Tie System Backup
Combined with a grid-tie inverter system the Sunny Island can be used to backup critical loads in the event of utility grid blackouts. Connected to a bank of batteries, the Sunny Island helps keep grid-connected systems running anytime the sun is shining. The loads are actually powered directly by the grid-tie system on sunny days and by a battery bank at night. If the grid-tie inverter has a 240 VAC output, a backup system will require two Sunny Island inverters or one inverter and an autotransformer.
