If the cFos Charging Manager cannot find the SunSpec registers, because for your device the starting address is not 40000 or 50000, you can specify it by adding parameters to the device address, e.g. 192.168.2.111:502 3 60000. If your device supports several SunSpec Models, you can skip the first n Models by adding a parameter n, like so: 192.168.2.111:502 3 60000,1 (skip one Model).
Add a parameter to the device address, e.g. 192.168.2.111:502 3 40000 or 192.168.2.111:502 3 40000,1.
| 40001 | Default M103 Solar inverter |
| 40001,1 | M203, root meter |
| 40001,2 | M203, additional solar power |
Add a register number to the device address, e.g. 192.168.2.111:502 3 40068.
