Sunny Boy SB7.0-US Inverter
Cost effective with powerful features
The Sunny Boy SB 7.0-US inverter, one of SMA’s new series of transformerless inverters represents the next step in performance for UL-certified inverters. The inverters are both economical and installer friendly. The transformerless design means the inverters are high efficiency with reduced weight and also less heat gain for the inverter. In addition, maximum power point tracking (MPPT) is derived from wide input voltage and operating temperature ranges, allowing for many stringing configurations and multiple independent MPPTs.
Shading issues have also been address in this new US series of inverters. SMA’s OptiTrac Global Peak shade mitigation technology provides a solution for both shade mitigation and the problem of installation on more complex roofs.
The newer version of the Secure Power Supply (SPS) feature now enables these Sunny Boy inverters to supply 2,000 watts of power in the event of a grid outage, as long as the sun is shining.
The SMA Sunny Boy US series now includes enhanced communications with no need to install additional equipment. Integrated WiFi or Wired datalogger and output to Sunny Portal for monitoring are now included, as well as direct access via a smartphone and use of SMA’s Installation Assistant.
Each inverter is covered by a 10-year warranty, which can be extended to 15 or 20 years.
