I recently bought a Macbook and found that whilst charging
from the on-board mains ring (using the Apple-supplied charger) it interfered with my mobile/cell phone
if in close proximity, and also just about anything else connected to the Macbook - CD/DVD read/writer, external backup drive etc. I could even get a tingling sensation when touching the Macbook. Apple kindly swapped it out for a new one (which included a new charger), but the same problem is still evident, so the issue is clearly mine, not the Mac.
In a bid to find the source of the problem I switched off my Victron Multiplus 12/1600 charger/inverter and the problem disappeared. I'm presently connected to shore power
and have the inverter
physically switched off at the unit (as opposed to switched off at the Phoenix remote
panel). As I understand it, with the Victron turned off the shore power
is connected directly to the boat's mains ring via a relay in the Victron unit, but I have no idea what route
it takes within the Victron when the unit's turned on. Out of curiosity I disconnected from shore power and turned the inverter
on, not surprisingly the problem still existed - it's clearly something to do with the Victron.
Has anyone else experienced this with a Victron charger
, or better still, experienced and fixed it? I've done a search on the forum site, and a Google
search, but come up with nothing.
Incidentally, I checked that nothing else was connected to the on-board mains ring when testing - just the Macbook charger
- and even turned off all 12v devices. Also worth mentioning is that I've never before experienced interference
problems with anything else on board.
