How to restore an inverter to factory settings?

Restoring the inverter to factory settings allows you to revert any personalized operational changes back to the original state. Generally, the factory settings are the most universal and widely applicable configurations, designed to meet the usage habits of most users and suit the majority of application scenarios. Therefore, unless you have a thorough understanding of the device's characteristics, it is advisable not to modify the settings arbitrarily.

The method for restoring factory settings varies among inverters from different manufacturers. Today, we will demonstrate how to restore factory settings using an inverter independently developed and produced by Nanjing Oulu Electric Co., Ltd. Let's learn together!

1. While the inverter is in the stopped state, press the PRG key to enter P0 (as shown in Figure 1).

2. Press the Up key to change to PP (as shown in Figure 2).

3. Press DATA, then press the Up key to change PP-00 to PP-01 (as shown in Figures 3 and 4).

4. Press DATA again to make the panel display 000 (as shown in Figure 05), then press the Up key to change the value to 001 (as shown in Figure 06).

5. Press DATA to save (as shown in Figure 07).
