Hello, I experience a strange behavior with an ESS system with Multiplus 3000/48 + Solar MPPT + CCGX + Pylon US3000c.
When the grid is OFF, all is running fine : Solar energy is going to house and battery and the house take power from battery if needed.
If I turn ON the Grid input, the multiplus stop to use solar et battery to power house and use its transfer mode from grid only. Solar is only used to charge the battery (if not full; when full the solar is around 0W).
Sure all firmware are to date and I checked 2 times my VE config, try to turn OFF (and disconnect all powers 3 minutes on the multi, try to restart several times the CCGX, try to intialise the multi from CCGX menu and so on....and the Bus-can cable is OK with 3000c (type A with ground wire on pin 6 instead of 2). I cannot understand why the multi stills in transfer mode with grid ON.
An idea for something I did not check
