1. If it is a resistance-capacitance type, it is necessary to increase the capacitance, and to increase the capacitance, it is necessary to increase the voltage resistance of the capacitor.
2. If it is a transformer, increase the secondary winding of the transformer, and check whether the transformer has a pile head of 24V to 12V. If not, add a small transformer of 1 pair 2 before the main pin.
When selecting and using frequency converter, you must pay attention to:
1.DC voltage must match: each inverter has a nominal voltage, such as 12V, 24V, etc.
2. The output power of the inverter must be greater than the maximum power of the electrical appliance: especially some equipment with high starting energy demand, such as motors and air conditioners, need extra power margin.
3. The positive and negative poles must be connected correctly: the DC voltage connected to the inverter is marked with positive and negative poles. Generally speaking, red is the positive electrode and black is the negative electrode. The battery is also marked with positive and negative poles, with red as the positive pole and black as the negative pole. When connecting, be sure to connect it backwards and forwards.
4. The charging process and the inverter process cannot be carried out at the same time, so as not to damage the equipment and cause failure.
5. The inverter shell should be properly grounded to avoid personal injury caused by leakage.
