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