SUNNY BOY 3000US / 4000US

The Sunny Boy 3000US and 4000US are the first of the new “US” series of Sunny Boy string inverters. They have been updated with our most advanced technology and are designed specifically to meet the new IEEE 1547 requirements.

Their compact design makes them ideal for light commercial or residential use and the integrated DC disconnect makes installation more cost-effective. They are field configurable for positive ground systems making them more versatile than ever. Increased efficiency means better overall performance and shorter payback periods. Each are engineered and built to last and now come with a standard ten year warranty. Sunny Boy inverters are trusted worldwide to go the distance.
