[T6] New Conversion Electrics Schematic Check

[Ninj43]

Hi all,

Can some kind soul please cast an eye over my proposed electrics please. No solar

Using the following:

230Ah Seatbase Battery (still to buy)
Victron Orion TR 30A DC-DC charger
Victron Smart Shunt
Renogy 2000W Inverter

Couple of things to clear up please

• What is recommended between DC-DC charger and positive busbar in terms of isolation/fuse?
• What size fuse do I need between 230Ah leisure battery output and positive busbar?
• What benefit will I see from swapping out the DC-DC for the new 50A - I've never noticed the 30A getting excessively hot in old van
• Have I got the Smart Shunt in the right location?

Thanks in advance

Anyone able to advise on the fuse ratings please?

25mm2 wiring from seatbase to bus bars probably should be 35mm2 - same as inverter to bus bar.
200A fuse should be at the bus bar end of the cable rather than by the inverter
Fuse by seatbase should be at least 200A

Cheers - any suggestion on what form of protection to use between DC-DC charger and positive busbar?

You should consider something like a power distribution block instead of a +ve bus bar.(this one from 12 volt planet)
Every time you step down the cable size as you move away from the battery , you need an appropriate sized fuse to protect the new smaller cable.
This would allow you to fuse the inverter cable at 200A, the dc-dc cable at 60A and the fusebox cable at whatever is suitable for the fusebox cable size . You also have spare for if you fit solar etc

Perfect thanks, save some space too

So something like this.......
