7.8kW Grid-Tied Solar Kit with SMA Sunny Boy Inverter


Kit price saves over $1,430 compared to buying all components separately! This comprehensive solar kit includes everything needed to build a roof-mounted solar PV system, including racking, flashing, and wiring. The PV modules - 26 of Canadian Solar's 300-Watt CS6K monocrystalline panels - can be installed in up to 3 separate strings, all of which are MPPT tracked by the inverter.

SMA voted top inverter brand by IHS 5 years in a rowThis grid-tied solar kit includes SMA's state-of-the-art Sunny Boy 7.7-US inverter, which offers a continuous 7.68kW output at 240 AC volts (6.66kW at 208V). The most impressive feature of the Sunny Boy 7.7 is its Secure Power Supply: the ability to send up to 2000 Watts to a dedicated outlet inside the house when grid goes down but the sun is still shining. Solar power during a grid outage - with no batteries!* This feature - combined with triple MPPT string inputs and SMA's proprietary OptiTrac™ Global Peak shade mitigation technology - provides great flexibility in system design, which is especially helpful for complex roofs and shading challenges.
