Im prerunning some cables while I'm installing some other bits. Could you helpful chaps confirm the below is correct please. This is for my leisure battery.@Dellmassive

Wiring in Victron 12/375 leisure battery
- Thread starter dErZ
- Start date
10mm2 cable - yes.
It's rated 375va but can do 700w peak.
..
As for fuse...
I'd fit a 60A MIDI fuse, as the 375 will pull just over 30a when running and 58A peak .... So a 30a fuse will get hot or blow under load.
Heres a link to the manual..
.
...
If the inverter is the only mains in the van you can loose the earth and set the inverter floating.
If you have other mains.... Ie hook up etc then look at the implications.

Thanks for your help and advice @Dellmassive, I do have EHU and it's earthed to the van. What does this mean in relation to earthing the inverter ?

Are you running the inverter to seperate sockets from the EHU sockets?
How is it /will it be wired up?
Got some pics?

I would stick with a conservative choice of 30A fuse -
PS. At the maximum I could go for 40A fuse if the load indeed would be continuous at inverters maximum capability.
- Max continuous output power of the inverter is 300 W, thus on the feed side 330 W (taking into account the efficiency 90%). 30 Amp fuse allows 30 Amps "forever" which equals to 360 Watts.
- Peak power 700W to start-up LEDs, filament bulbs or electric tools shouldn't last very long. 30 Amp fuse will withstand 60 Amps at least 5 seconds which should be more than enough.
- Internal 80A fuse in the inverter is not replaceable.

The inverter will only be used for powering laptop/screen when Im out and about 'working' I will run a totally seperate 3 way extension from the inveter so theres no physical link connection to the EHU (apart from the EHU is earthed to the ground under the passenger seat) (the EHU only gets used when the van is sat for long periods on the driveway to charge the leisure/starter battery the EHU does have a 4 way on it)
Looking in the manual it talks about moving the internal PE wire but Im perplexed as to if this needs to be done in my scenerio??
Im currently making up the cables for the mppt/inverter so want to run them all while I have the seats out.
Thank you for your help. @Dellmassive

If the inverter is totally separate from the EHU electric s, and you are using a separate extension lead that's again isolated or seperate from the EHU wiring....
Then you don't need to ground the inverter....to the chassis or the external floor.
Victron say it's a safer install to leave the inverter floating.
......
If the inverter was tied in with the EHU and transfer switch using the same sockets then it would need chassis ground.

The above has answered my question about grounding the 1200w Victron pheonix.
but i am just wondering about a fuse between battery and inverter though, my poss cable is about 500mm, so going by the manual i shouldn't need an additional if under 1500mm long.
would that be correct or should one be popped in for safety? if so what size?

Victron Pheonix 1200va inverter:
150Ah worth of 12v batteries
200A supply fuse
25mm2 cable for up to 1.5meter
35mm2 cable for 1.5-3meters.

It is a 230Ah battery but i have added a 200amp fuse between battery and inverter (on poss)
one other thing i am not 100% sure of (googlr has been no help) - on the ctec there are 2 small wires, the red one is the ignition feed as smart alt on T6, the other one a red/blk i am not sure if this is just left OR if is should go to vehicle ground?
