Product Features of the Solar Automatic Transfer Switch
Engineered with a robust PC-Class change-over mechanism, this Solar Automatic Transfer Switch guarantees safe electrical isolation during emergency AC power shifts.
- High-Speed Conversion: Executes automatic switching within 50 milliseconds, minimizing downtime for sensitive 400V AC commercial loads.
- Dual Power Configuration: Tailored for PV solar installations where Source A connects to the inverter’s AC output and Source B links directly to city power.
- Robust Fault Withstand: Resists massive grid anomalies utilizing a 50kA rated conditional short-circuit current capacity and an 8kV impulse withstand voltage.
- Broad Rating Compatibility: Supports versatile system sizing, functioning seamlessly as a heavy-duty ats 125 amp configuration or scaling down to 16A.
