Photovoltaic inverters

PVI 1000

The Switch photovoltaic inverters (PVI) are specifically designed for utility-grade solar applications to optimize solar power harvesting and LCOE (Levelized Cost Of Energy) in central inverter megawatt-scale photovoltaic power plants.

Each system component is chosen to maximize system performance, efficiency and uptime for optimum overall power generation and plant revenue throughout the lifetime of the power plant.

The Switch PVI design offers up to 98% efficiency, and total current harmonic distortion is typically less than 3%.

Features	Advantages
Rugged IP66/Nema 4 enclosure	Totally sealed and self-contained inverter assembly, resilient for outdoor installation in harsh ambient conditions, eliminating costs of additional housing or cooling

One shipping unit	Complete, compact unit shipped in one single “plug and produce” assembly

Integrated liquid-cooling system	Self-contained liquid-cooling system, factory filled and tested, with no need for onsite piping or plumbing, simplifies operation, maintenance and installation

Grid compliance and support	Field-verified compliance with evolving utility needs that includes fault ride-through (FRT) functionality; continuous active and reactive power stabilizes grid voltage and frequency during grid disturbances, varying voltage fluctuation and electrical system fault conditions

Power saving and standby mode	Energy-efficient temperature management system minimizes power consumption and tare losses

Built-in diagnostics	Robust, built-in features for monitoring, diagnosing, data logging and reporting ensure optimum performance and system availability

Specifications

The Switch PVIs comply with the latest national and international standards set for grid-tied operation, safety and electromagnetic compatibility, including UL508C, UL1741, NEC690, IEEE 929, IEC61683, IEC61727, EN50081, EN50082, EN61000 and FERC661A.
