6 FAQs about [Huawei voltage inverter parameters]
What is a P-U curve in an inverter?
The standards of certain countries and regions require that the active power of the inverter be derated according to a certain slope when the output voltage exceeds a certain value. The standards of certain countries and regions require that the P-U curve be set. This parameter is displayed when Voltage rise suppression is set to Enable.
What is the maximum input voltage for a smart string inverter?
Smart String Inverter Recommended max. PV power *1 The maximum input voltage is the upper limit of the DC voltage. Any higher input DC voltage would probably damage inverter. *2 Any DC input voltage beyond the operating voltage range may result in inverter improper operating.
How to increase the over voltage protection of the inverter?
For example: if the inverter generate very often the alarm over voltage due to the grid voltage range, you can select the over voltage protection, increase with 10V and confirm. 2. Set the running parameters through NetEco
How does the inverter adjust the output power factor based on p/pn?
Cosφ-P/Pn characteristic curve The inverter adjusts the output power factor cosφ in real time based on P/Pn (%). If this parameter is set to Enable, the inverter responds to the scheduling instruction from the remote port.
How do I set inverter parameters?
To set inverter parameters, tap Settings. For details about the parameters, see FusionSolar App and SUN2000 App Device Commissioning Guide. You can also scan the QR code to obtain the document. The output current of the PV power system can be limited or reduced to ensure that the output current is within the specified range.
What is inverter protection threshold?
Value range: [0.05, 1.5]. Specifies the inverter protection threshold when the power grid voltage is unbalanced. The Japanese standard requires that during passive islanding detection, protection should be triggered if an abrupt voltage phase change is detected.
