Step 3: Repair the inverter

After we have sufficient manpower and material, we will send our technical department down to repair. (In some cases we may have to bring it to the company's factory for processing)

During the repair period, we will lend your available inverter to customers for use in the meantime.

Step 4: Check, test run

After fixing it, we will carry out a final master check and then test run for about 30 minutes to 1 hour. If nothing else arises, Dai Duong Corp will proceed with the handover.

Step 5: Handing over and paying.

When the inverter has stable operation, our staff will make a handover record, write a warranty for you. Finally, you will pay the full cost according to the quotation that we sent earlier.

During the warranty period, if there is any problem with the inverter, please contact us immediately. Dai Duong Corp will send its maintenance department to handle immediately to avoid affecting your usage process.
