SUNNY BOY 3000US / 3800-US / 4000US

Reliable system managers with UL certification  

The Sunny Boy 3000-US, 3800-US and 4000-US inverters are specially designed for countries that require UL certification. The automatic grid voltage detection* allows easy and safe installation. The integrated DC switch-disconnector simplifies installation and saves costs. Since the devices are suitable for generator grounding, they can be combined with all types of modules. The die-cast aluminum enclosure, with the OptiCool active cooling system, guarantees the highest yields and a long service life, even under extreme conditions. The Sunny Boy 3800-US is tailor-made for installations requiring a current limit of 16 A.
