First, the product introduction
Product Name: Photovoltaic special inverter
Product brand: WeiKen
Voltage level: 220V/380V
Second, the product description
The PV special frequency converter has built-in MPPT controller, and has excellent MPPT algorithm for various solar panels. The main circuit adopts intelligent power module, which has high reliability and conversion efficiency of about 95%. It is especially suitable for photovoltaic generators, such as fan and water pump. load.
Third, the characteristics of the injection molding machine servo drive
1. Support boost module less than 2KW to increase PV output voltage;
2. The speed adjustment range of the pump can be set freely according to the actual system conditions;
3, soft start, reduce the top voltage pulse, with overvoltage, undervoltage, overcurrent, overload and other protection functions;
4. Support photovoltaic input and AC grid input;
Fourth, matters needing attention
1. Do not overload the inverter. For example, the inverter power is smaller than the motor power, or the ordinary motor is greater than 50HZ. Otherwise, the inverter will frequently skip the protection fault, even the bomber, the motor may overheat and burn out;
2. The default upper limit frequency of the inverter is 50HZ. The default function is off. If you need to change, please contact the factory for sale or follow the instructions for correct operation.
3. No switch can be connected in series between the output terminals U, V, W and the motor, including the contactor. The inverter cannot be used as the power supply. The inverter cannot be connected to any equipment through the switch.
4, the external control distance of the inverter operation panel should not be too long. If it exceeds 5M, it is recommended to use the external potentiometer to adjust the speed and connect with the shielded wire. The start and stop control can use the terminal control mode;
5. The panel connection cable is too long to be subject to harmonic interference, which makes the inverter frequency control inaccurate and the frequency fluctuates greatly;
6, DC input voltage, please try to meet the recommended voltage, otherwise it will reduce the solar energy conversion rate;
7. The AC input and DC input switch cannot be closed at the same time, otherwise the inverter or solar panel will be damaged.
