Victron 3000VA MultiPlus-II kit

Our Victron MultiPlus kits include everything you need to connect an inverter/charger subsystem to your electrical system. All cabling, fuses, cable lugs, etc. are included, as well as a number of optional extras to enhance the system.

We supply consumer units which contain 1x 25A RCD, 1x 10A MCB and 1x 6A MCB. We include two additional 16A MCBs so you can harness the full power of your MultiPlus.

The DC cable gauge is specced on the distance between the MultiPlus and your busbars being no longer than 1.5m each way (3m ‘there and back again’ length). If your inverter/charger will be further away than this, please contact us so we can provide a system proposal with the correct cable gauge.

We supply 20m of 3 core cable. This is used to connect the shore inlet, consumer units and MultiPlus, as well as wire any 230V sockets and appliances. If you require more cable than this you can add additional 3 core cable to your order separately.

You have the option to add a Blue Sea 600A switch. This allows you to easily isolate the subsystem from the rest of your electrical system.

We include an MK3 to USB-C interface and RJ45 cable, so you can configure the settings for the MultiPlus from your computer.

If you’d like to monitor your MultiPlus from a Cerbo GX, you’ll need to purchase an additional RJ45 cable.

Select whether you will use busbars or a Lynx Distributor to connect your subsystems to your batteries. Please note that the busbars / Lynx Distributor are not included in this kit, however by selecting what you are using in your system, we can ensure we include the required fuses and fuse holders.

Choose from the Victron polyamide or Victron steel shore power inlet. Both are rated to 16A.

Select if you would like to include a Victron shore hookup cable. It’s not possible to use an unbranded hookup cable with the Victron inlets, so if you don’t already have one you should include this.

Wiring diagram & installation guidance

All of our kits are supplied with a subsystem wiring diagram and installation guidance. This includes information on setting up the MultiPlus correctly using the MK3 to USB-C interface cable. So, you can install your system easily and be confident it’s installed correctly. If you need any support during the install, contact us and we can provide additional support.
