The input cannot be connected to AC power, let alone 220V AC power 2. The maximum input voltage cannot exceed 38V. It is recommended to use it within 36V, and the positive and negative poles cannot be connected in reverse. 3. When connecting the output terminal to the battery, be careful not to connect the positive and negative poles in reverse.
