Introducing the new Sunny Boy US inverter series, a revolutionary step forward in bottom line savings and the next generation of residential PV technology. Robust feature set and simplified design mean reduced costs for residential solar installations. The Sunny Boy US features an integrated DC disconnect, simplifying the installation and providing a safe system operation.
It features multiple independent input channels, each with SMA OpticTrac technology. This allows for hundreds of possible string configurations, even on roofs with complex layouts and shading issues.
Enhanced communication capabilities remove the need for additional equipment in system monitoring; the ethernet or wireless connection to SMA sunny portal facilitates a superior monitoring solution. SMA installation assistant and smartphone commissioning capabilities make getting systems up and running faster and easier than ever before.
In the event of a daytime grid failure, SMA Secure Power Supply (SPS) can produce up to 2,000Watts of energy directly from the solar panels and without the added expense of batteries.
The inverters two-part design separates the connection unit from the power unit, ensuring simple expedited servicing. The enhanced AFCI provides improved sensitivity for detecting arcs and less issues with false tripping allowing for greater safety and a reduction in troubleshooting.
Additional advanced features, like it's off-grid capabilities and full grid management functionality, make this the most advanced Sonny Boy yet, offering a superior residential solution.

The Secure Power Supply (SPS) feature is included in the new SMA Sunny Boy US-40 series inverters. It is SMA’s battery-less solution for daytime power outages. The SPS can provide up to 2000W to a dedicated outlet wired directly to the Sunny Boy inverter.
As with the previous version of the SPS, you will need a switch, grounded outlet, box and conduit in order wire and benefit from the SPS feature built into the selected SMA Sunny Boy inverters. The SPS output in the US-40 inverters is 2000W so the equipment and wired installed needs to be able to handle the 16 Amps of current the SPS can supply.
The SPS can be installed during the original solar installation or later on as a retrofit. Please note that not all Sunny Boy inverters include the SPS feature.
The best way to test the correct wiring of the SPS is to decommission the inverter and turn off AC breakers to simulate a grid failure. Once the correct functioning of the SPS is verified, turn off the SPS switch and turn back on the AC breakers to connect the inverter back to the grid.
SMA America started in Germany in 1981 and is a pioneer in photovoltaics power conversion. Today they are the number one inverter manufacturer worldwide with presence in 15 different countries, including the United States and Canada. In 2011 they opened the solar academy in California to help installers understand SMA’s technology and bring that knowledge to the home of thousands of homeowners in the US.
SMA staples include the Sunny Island inverters for off-grid and remote applications and the Sunny Boy inverters for residential and small commercial applications. In recent years they added the Tripower line of commercial inverters ranging from 12kW to 30kW per unit. Some of their inverters are assembled in Colorado and qualify for the ARRA Recovery Act. All their units are UL listed and comply with the most recent requirements in the National Electric Code (NEC).
SMA America has raised the bar in the solar industry for over 30 years and they continue to do so. They cover a wide range of applications and system sizes. The new inverter models with grid-tie applications come with multiple MPPT channels that will provide increased flexibility for your design and the length of you PV strings. This is a required feature when working with challenging roofs such as odd shapes or significant shading.
Additionally, SMA provides their Sunny Portal free of charge to SMA users. It is one of the most advanced energy communication platforms; all SMA inverters can transfer production data to the Sunny Portal. The portal is accessible to system owners via the Internet, where they can view and monitor their system’s performance in great detail.
