Hi
I'm new here and new to Victron Products - I have just picked up a used Multiplus 12/3000/120 and am just doing some planning before installing into my boat. I'll have heaps of questions but i'll post them one by one.
The boat already has a 240v system and this will be integrated into it, however I have some questions.
The boat has a couple of heavy draw items the main one being the water heater (works on engine but also 1800w element) which I obviously do not want to be connected to the Multiplus.
My question as this is an older multiplus, and doesnt have AC out 2, is how do people generally wire for this type of system, i'm thinking the shore power / genset feed gets split into the inverter and also into a separate feed. This way the hot water operates on genset / shore and the remainder of the mains sockets can operate off the inverter (heaviest of loads will be the kettle which may get used a couple of times per day) but i'm figuring this will need another MCB / RCD protecting the split non inverter side..
As an aside I have 800ah of batteries split into 2 banks of 4x 100ah each bank on either side of the boat, combined by a selector switch and cables all the same length to the centre of the boat. then a single 12vdc cable out to house loads - this will include the inverter but wiring will be upgraded to 95mm2 as the main feed and 70mm2 from each bank to the selector
If anyone has any wiring diagrams to share that would also be awesome..
