SMA US-41 Inverters
SMA America is producing the US-41 series of string inverters. The SMA Sunny Boy 6000W Inverter SB6.0-1SP-US-41 features an integrated DC disconnect, simplifying the installation and providing a safe system operation. It features multiple independent input channels, each with ShadeFix technology. The new technology allows you to install the solar panels in numerous possible string configurations, even on roofs with complex layouts and shading issues.
Sunny Portal Communication
Enhanced communication capabilities remove the need for additional equipment in system monitoring. The connection to SMA Sunny Portal facilitates a superior monitoring solution. It gives you lifetime access to SMA Smart Connected. SMA installation assistant and smartphone commissioning capabilities make getting systems up and running faster and easier than ever before.
All US-41 SMA inverters are SunSpec certified shutdown devices to achieve compliance with NEC 2017 module-level shutdown. They also provide advanced AFCI compliance to new Standard UL 1699B Ed.1 for arc fault protection. The AFCI feature delivers improved safety and reliability while allowing for automatic resetting. Do not be concerned about California Rule 21; it is easy to configure the inverter with the required values.

Secure Power Supply
The Secure Power Supply (SPS) feature comes standard with the SMA Sunny Boy US-41 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.
To benefit from the SPS feature, you need a switch, grounded outlet, box, and conduit to wire (not included with inverter). The SPS output in the US-41 inverters is 2000W; the equipment and wires installed have to be sized to handle the 16 Amps of current the SPS can supply.
Install the SPS during the original solar installation or later on as a retrofit. Please note that the Secure Power Supply feature is not compatible with SMA TS4 module optimizer units.
