However, the seller said that his sons' vehicles also experience the same problem. Therefore, I have decided to install a Dual Battery Isolator 12V under the bonnet to ensure that it shuts off.
You've severed the charge path. As such the unit doesn't see an 'output' path and doesn't possess the error code handling to produce any output other than "PANIC!! DISPLAY ALL LIGHTS!!" Unplug it (switch master/main power batt off) and the unit has no power, thus no display lights. Typical Chinesium controller programming. Nothing to see there.
is there a brand on the DCDC charger? maybe fault code in a the user manual?
