Why the 5 kW

Highest efficiency in the single phase range - SiC MOSFET stages with 98.2% conversion.

Two independent MPPT inputs handle shading or split-orientation roof layouts seamlessly.

No fans means zero moving parts, reduced noise, and lower maintenance over the system life.

Anti-islanding, SPD, RCMU and short-circuit protection - all integrated, no add-ons needed.
