To start Eltek and control it you only need one CAN telegram ID and you need to connect it to AC.

1. Connect charger DC output port to 2x light bulbs in series for protection
2. Connect charger to AC
3. Charger should be sending its status report when it is connected to AC, IDs are 305, 306, 307 and 308
4. send this CAN telegram to control charger ID 2FF MSG 01 E8 03 6E 0F 32 00

I have written here how command telegram works
