Hi all- we have a Hanse 388 with two 12/2500 Mastervolt lithium batteries
, Balmar alternator
, EasyView control panel
, 2500 W Mastervolt inverter
We've had two bad experiences- one prior alternator
, inadequately cooled, caused winding insulation
to burn off with smoke and excitement; and more recently some sequence of C-zone overvoltage (14.82V); diode burnout on alternator, leading to uncontrolled current
into Li batteries
, shutting engine
down stopped that.
I'm good at recording everything when something goes wrong- taking still and videos of any metering, etc, for later analysis.
My question is- what basic immediate operational procedures should I know? I didn't know how to stop the alternator charging
using the EasyView panel (I plan to be taught). I am not sure whether it's safe to disconnect the batteries with their yellow isolator switches while they are charging- I assume it is if engine
is off. Do any of you have a checklist of tasks one should know how to do with this sort of system? One might start with top five things that can go bad and how to mitigate and troubleshoot...I have read the Mastervolt manuals
and have Nigel Calder's Mechanical and Electrical
