Description

The Sunny Boy SB7.7 1SP-US-41 by SMA is an advanced grid-tie PV string inverter with features that make it the leading choice for residential and commercial solar power systems. At 7.7kW, it is ideally suited to solar arrays in the 8-10kW range, or multiples. The innovative SPS or ‘Secure Power Supply’ feature provides power from the roof to a dedicated outlet even when the system is disconnected from the grid during an outage – something no other string inverter does. A practical level of back-up power security without the expense.

The Sunny Boy brings more value-added features to your solar installation including…

• ShadeFix
  SMA’s outstanding ShadeFix optimization offers superior string-level optimization. No more DC optimizers! This means lower system cost, and maximum reliability.
• SunSpec RSD
  SunSpec Certified rapid shutdown technology is the simplest way to achieve code compliance.
• Wide MPPT Input Voltage Range
  This provides latitude for both optimization, and for array layout.
• Triple MPPT Input
  3 strings for flexible array configurations
• Advanced AFCI
  Compliant to new Standard UL 1699B Ed.1 for arc fault protection – delivering improved safety and reliability while allowing for automatic resetting
• Secure Power Output
  All PV inverters must disconnect from the grid for safety during a power outage, but your Sunny Boy solar array can keep powering a dedicated outlet direct from the inverter! A fantastic emergency back-up power option for any home. Use the outlet to directly power loads during the day such as a fridge, or use the energy to charge a battery pack like the Yeti 1500X, Yeti 3000X, or Socrates 1200 for stable power anytime, day or night!
