Matters needing attention in the use of frequency converter
1, DC voltage should be consistent, and each inverter has the voltage value connected to DC, such as 12V, 24V, etc. And the battery voltage must be consistent with the inverter DC input voltage.
2. The output power of inverter must be greater than the use power of electrical appliances, especially those with high power when starting, such as refrigerators and air conditioners.
3. The positive and negative poles must be connected: the DC voltage connected to the inverter is marked with positive and negative poles, red is the positive pole, black is the negative pole, and the battery is also marked with positive and negative poles, red is the positive pole and black is the negative pole. When connecting, you must use positive and negative electrodes to connect.
