I am using a Victron Blue Power Control to operate an Easyplus Compact 12/1600/70. On the Blue power control screen the EasyPlus was automatically (years ago) named "PHOENIX MULTI". I could normally toggle between charger, inverter or (when switched off:) switched off. All I see now is CHECK DEVICE or SWITCHED OFF. Fortunately the charger and inverter are still working properly with the check device message shown. What to do to solve this?
