A recently filed patent (Publication Number: US20230206248A1) describes a method for maintaining a power conversion system. The method involves transmitting an alert message to a computing apparatus that is in communication with the power conversion system. This alert message indicates the presence of non-working microinverters and provides information on how many of these microinverters are eligible for replacement under warranty. The computing apparatus then sends a request for replacements for the non-working microinverters, and the power conversion system transmits an acknowledgment message to confirm that the request has been successfully received.

In addition to confirming the receipt of the request, the acknowledgment message may also indicate that replacements for the non-working microinverters are being shipped. The request for replacements can include various details such as the serial numbers of the non-working microinverters, the status of these microinverters, and the shipping addresses to which the replacements should be sent.

The method also includes the transmission of an agreement message to the computing apparatus, providing the user with the option to accept or decline the terms stated in the message. The acknowledgment message sent by the power conversion system includes a request identification (ID) number that allows the user to track the status of the replacements for the non-working microinverters.

The alert message, which triggers the entire process, is determined automatically based on the condition of the non-working microinverters and an auto-approval algorithm for return merchandise authorization (RMA). Furthermore, the power conversion system can receive a change of shipping address, specifically an installer address, as part of the request for replacements.

The patent also includes a non-transitory computer readable storage medium that contains instructions for performing the method described above. This medium can be executed by a processor to carry out the steps of transmitting the alert message, receiving the request for replacements, and transmitting the acknowledgment message.

Overall, this patent presents a method for efficiently maintaining a power conversion system by streamlining the process of replacing non-working microinverters. The use of a computing apparatus and automated messages helps to simplify and expedite the replacement process, ensuring that the power conversion system remains operational.
