Dual Power Transfer Controller NV-Q
In some application where there is a stand-alone solar or wind system with available main supply, one can choose to use the energy stored in the battery first and when the inverter disconnects due to low battery voltage, the controller will automatically transfer the loads to the second mains(such as public power). The NV-Q range of power transfer controllers switch reliabley between inverter and AC mains power with priority circuit and fixed network operation. The controller avoids damage to inverters and batteries and is suitable for off-grid wind or solar systems. Transfer time less than 10ms.
Key Product Features:
- Controller is reliable between inverter and AC mains .
- With priority circuit and fixed network operation.
- Transfer to second AC Voltage automatically.
- Avoids damages on the inverter and battery .
- Suitable for the off-grid wind or solar system.
