How It Works
The ATS50 acts as an intelligent bridge in hybrid solar systems, managing power transitions between the grid and a diesel generator. When the grid fails or drops below set parameters, the ATS signals the generator to start and switches the supply to generator output. Once grid power is restored, it seamlessly reverts back, keeping connected loads continuously powered.
This automated switching improves reliability, protects sensitive equipment, and eliminates the need for manual intervention, making it ideal for commercial and industrial hybrid energy installations.
Applications
- Commercial hybrid solar energy systems
- HPS50 inverter installations with backup generators
- Critical load applications requiring continuous power
- Remote or off-grid facilities requiring automated source management
