Re: Victron Quattro charger/inverter installation

Hi Mohammad,

Be aware the battery chargers are connected to the "other side" of the main battery switches relative to the inverter. So before you start putting these cables in parallel you will need to change that (if not already). I'm not sure why Amel did this, but my guess is that you can keep a battery charger running even if all other things are disconnected.

This is why I was asking about the power-connection point in the engine room. It seems to be connected to the secondary side of the battery-switch with 95mm2 cables, more then enough to run a 4kW inverter instead of the 2kW version. I don't like changing too much the original config of the boat as it very often comes back and bites you, especially in a complex boat like the 54. So replacing the inverter seems to be limited to the inverter itself, the cable to the inverter, the circuit breaker in the gray cabinet needs to go up from 120A to 200A. and maybe the 230 V output cable needs to be bigger (2.5 mm2), I'm not sure. And of course some changes are required to the 230 switch panel to energize the washer etc. when running off the inverter. But It allows you to retain the original config for the most part.
