Description
SMA Sunny Boy 7.7-US
这SMA 7.7-US inverter features several improvements over the previous generation of Sunny Boy inverters including a wider voltage input window, three independent MPPT inputs, direct smartphone access and a Secure Power Supply. The 7.7-US inverter offers an industry-leading 100 volts DC minimum system voltage which means it will work with shorter PV strings and produce more power. The Sunny Boy 7.7-US includes three independent MPPT inputs which improves efficiency and design flexibility. Subarrays of panels can be installed on an East, West and South-facing roof top using the three independent MPPT inputs. The new Sunny Boy 7.7-US includes the Secure Power Supply feature which can output up to 2,000 watts of AC power during a power outage while the sun is shining.
This is the first grid-tied inverter from SMA to offer direct access via a smartphone. The SMA 7.7-US also includes an integrated DC disconnect switch with each inverter. The combination of three MPPT inputs, Secure Power Supply, direct smartphone access and integrated DC disconnect make this one of the most cost-effective inverters available. Three MPPT inputs is especially useful for PV arrays with shading or complex roof tops with multiple sub-arrays.
Warranty
10-year warranty is standard, 15 and 20 year warranty extensions available.
注意:安装在建筑物上的所有PV系统都需要快速系统关闭。SMA系统需要其他硬件以快速关闭,您可能需要根据安装和本地要求添加额外的组件:
For NEC 2014: SMAs快速关闭框is a cost-effective solution to meet 2014 NEC 690.12 Rapid Shutdown requirements.
对于NEC 2017:可以将优化器添加到每个模块中,以符合2017 NEC 690.12系统快速关闭的要求。这TS4-R-Fprovides the necessary safety features and is the most cost-effective solution for NEC 2017 compliance. SMA offers a full line of optimizers with monitoring, shade mitigation and module optimization features,点击这里for the complete list of options.
Note that using TS4 optimizers will disable the Secure Power Supply functionality of the inverter.
