This Solar Sky Grid-tie System is designed around the SMA Sunny Boy inverter and 20 JA Solar 315W Silver Poly Panels. Complete with MC4 extension cables, SMA inverter system, durable IronRidge racking, AC disconnect/shutoff switch and an Electrical Design Drawing, you'll be ready to use the power from the sun in no time.

At the heart of every PV system is the inverter and we have included SMA's new ultra-high efficiency transformerless inverters packed with features allowing you to convert the greatest amount of sunlight into usable energy.

• Wide Voltage Range - Allows power generation in a variety of conditions
• Secure Power Supply - Provides backup power in the event of daytime power outage
• Triple Maximum Power Point Trackers - Increases design options and panel configurations
• Transformerless Design - Reduces weight while increasing efficiency
• Sunny Portal Monitoring - Provides real time data to any home or mobile device
• Easily add Rapid Shutdown* with TS4 optimizers or the SMA Rapid Shutdown Box (see related items)

Use Solar Power During an Outage

The SMA Sunny Boy inverters feature the worlds first Secure Power Supply which allows you to power appliances during a grid outage. The Secure Power Supply is a dedicated power outlet connected to the inverter (outlet recepticle not included) that provides up to 2,000 watts of 120v power directly from the solar array, allowing you to power essential appliances in an outage when sunlight is shining on your panels. It does not require any battery storage but a small battery backup system could be plugged into the Secure Power Supply for additional backup power capability, for example our Rolling Thunder RT-1000 backup system works great for this purpose.
