Canadian Solar – CSI-255K-T800

CSI Solar‘s grid-tied, transformer-less string inverters help to accelerate the use of three-phase string architecture for medium ground-mount applications. An NRTL approved, costeffective alternative to central inverters, these inverters are
modular design building blocks that provide high yield and enable significant BoS cost savings. They provide up to 99.0%
conversion efficiency, a wide operating range of 480-1500 V DC, and 9-12 MPPTs for maximum energy harvest.
