GEYA W2R-100 II Dual Power Automatic Transfer Switch (2P, 63A, Grey Solar Series)

The GEYA W2R-100 II Dual Power Automatic Transfer Switch (ATS) from the Grey Solar Series is engineered for highly reliable power transition in solar energy systems, home inverter setups, and backup generator grids. Rated under the strict AC-33iB utilization category, this PC-class device is fully capable of handling complex mixed and motor loads safely. It delivers high-speed automatic transfer between the primary line (inverter/solar system) and the secondary line (utility grid) in less than 50 milliseconds, ensuring sensitive domestic appliances, home servers, and routers operate seamlessly without shutting down or rebooting. The ATS provides both fully automatic operations and manual control override.

Features:

• Optimized for solar power systems, home inverters, and automated backup loops

• Advanced AC-33iB utilization category rating for robust handling of mixed and inductive loads

• Seamless ultra-fast transfer under 50ms protects electronic appliances from reboots
