GoodWe Static Transfer Switch STS200-80-10

GoodWe STS200-80-10 – Advanced Transfer Switch for Energy Storage Systems

The GoodWe STS200-80-10 is a high-performance transfer switch designed for commercial and industrial energy storage applications. It enables reliable and instantaneous switching between on-grid and off-grid modes, ensuring power continuity in any situation – even during grid failures. It's an ideal solution for hybrid systems based on inverters and for powering critical loads from photovoltaic panels, batteries, or generators.

Key Advantages of the Device:

Seamless switching between grid and island mode – The STS enables instantaneous switching (under 10 ms), guaranteeing uninterrupted power supply for critical loads.

High compatibility – Works with inverters, energy storage systems, and diesel generators, supporting power for heat pumps, motors, and other high-power loads.

High power and load capacity – The maximum power on the backup side reaches up to 138 kW, making the device ideal for industrial applications.

Resistance to external conditions – With an IP65 protection rating, the device is suitable for outdoor installation.

Natural cooling and high reliability – The absence of fans minimizes maintenance requirements and increases durability.
