    Which number on the caseback is the serial number?

    Hi All,

    First post here.

    I own a Rangeman GPR-B1000-1B, I am trying to figure out the serial number on the back.

    Can someone tell me which number on the back of the case is the actual serial number?

    There is an 11 digit number across the top as well, doesn't show too well in the attached pic.

    Regards

    It's the one at the very bottom of that photo, starting with "001".

    Edit: Too quick off the mark. I just checked the warranty card for my Rangemen, and all 3 of the numbers I've circled have been included next to "serial number". Very strange.

    @GaryK30 The number at the bottom does look like a batch code, doesn't it.

    That's not the batch code, which shows the factory and manufacture date?

    both the top and bottom numbers are serials, iirc top is jdm and the bottom is international coding...so the top one should also have 354 before a letter...the 354 is the day of the year.
    the one on the left is the batch number, which should mean 2018 December and whatever batch 9GXM means.

    Bottom code is the one that you can tell which factory and which date it was manufacturers. Im not familiar with factory code but 356H means its manufacture 356th day of 2018 (identified by the letter H). Only solar models have such code I was told.
