Fronius DPS 2500 - Device Production Year Calculation Method; Calculating Production Year from Serial Number

To calculate the year of production of the device:
- Each device is provided with a serial number
- The serial number consists of 8 digits - for example 28020099
- The first two digits give the number from which the year of production of the device
can be calculated
- This figure minus 11 gives the year of production
• For example: Serial number = 28020065, calculation of the year of production =
28 - 11 = 17, year of production = 2017
