Profitable PV Power

The Satcon® Equinox™ inverter has a significant impact on the profitability dynamic of large‐scale solar power systems. With its system intelligence, next‐generation MPPT technology, and industrial‐grade engineering, the Equinox inverter maximizes system uptime and power production, even in the harshest environments.

Rugged Design

Equinox features a IP54 enclosure, ensuring protection and longevity. It features a wide thermal operating range from ‐22° F to +122° F. With the optional Winter climate package, it supports temperatures as low as ‐40° F with an optional heater.

Industrial‐Grade Engineering

As a fully outdoor rated solution, Equinox does not require an external climate controlled enclosure or concrete station, reducing both cost and space requirements. Equinox’s double wall enclosure cooling system eliminates the need for external air circulation inside the inverter, reducing contaminants and improving cooling performance.
