Victron MultiPlus-II 12/3000Va with DC leads, isolator and mains wiring kit — 2400W of pure sine wave power plus 120A shore charging
Gives your campervan serious 240V power and shore-power charging in one unit. The MultiPlus-II 3000Va delivers 2400W of continuous pure sine wave — it runs almost anything you'd plug in at home, including induction hobs and full-size microwaves on medium. When you plug into hook-up, it switches roles and charges your battery at 120A.
The changeover is seamless. Shore power present: it charges your battery and passes mains through to your sockets. Shore power gone: it inverts from your battery to the same sockets. Automatic, instant, and silent — you never think about which source you're on.
The kit includes the DC battery leads and isolator, plus the mains wiring kit with the IP67 inlet and pre-wired consumer unit. Matched, specified, and ready to install — the complete 240V system for maximum power · full off-grid living.

🔌 What Can It Run?
The MultiPlus-II 3000VA delivers 2400W of continuous pure sine 240V power and provides up to 120A battery charging on hook-up. Here is what it can realistically run off-grid:
All Small Appliances
10-400W Phones, laptops, lights and TV together
✓
Standard Kettle
2000-2400W High battery draw — use sparingly
✓
Microwave
700-1200W No problem within the total limit
✓
Hair Dryer
1200-2000W Suitable for normal use
✓
Toaster
800-1500W Short use
✓
Air Fryer
800-1800W Check the appliance label
✓
Single-Ring Induction Hob
1800-2000W High battery draw — short cooking periods
✓
Two High-Load Appliances
2400W Combined loads above this exceed the continuous limit
✗
Combined Load Examples
Kettle + small background loads: keep the combined total at or below 2400W
Microwave + television + lights + device charging: typically around 1500W
Wattages are typical values — check each appliance label and combined rating. High-power cooking and heating loads draw substantial current from a 12V battery bank.
📦 What's Included
1
Victron MultiPlus-II 12/3000Va Inverter-Charger
2400W continuous pure sine wave inverter with built-in 120A multi-stage charger and automatic transfer switch. The flagship of the range.
2
DC Battery Leads & Isolator
Professionally crimped battery cables with isolator switch — sized for the inverter's current draw.
3
Mains Wiring Kit
IP67 inlet, pre-wired consumer unit with RCBO protection, connections specified for the MultiPlus.
⚡ Key Features
01Inverter and Charger, One Box
Inverts up to 2400W off-grid; charges at 120A on hook-up. One unit doing both jobs saves space, wiring, and cost versus separate devices.
02Seamless Changeover
Plug in at a campsite and it charges; unplug and it inverts. The transfer is automatic and in milliseconds — no switches to flip, no interruption to what's running.
03Pure Sine Wave, Safe for Everything
Clean output that's safe for laptops, medical devices, and anything with a plug. No modified-sine damage risk.
04Built-In Neutral Grounding Relay
The shore-to-inverter changeover happens through the Multiplus's internal neutral-grounding relay — a requirement under current regulations for inverter transfer switches. No external relay to buy or wire: changeover is safe and automatic.
🔧 Tech Specs

❓ FAQ
What can 3000VA run?
It runs almost anything you'd plug in at home, including induction hobs and full-size microwaves on medium. Total draw must stay under 2400W continuous — check appliance labels. Anything with a heating element is the big draw; LEDs and electronics barely register.
How much battery do I need?
Inverting at full power draws roughly 200A from a 12V battery. Lithium banks handle this; small AGM banks sag. Match the inverter to your bank: bigger inverters want bigger batteries.
Is this different from the Inverter Smart kits?
Yes — the MultiPlus range are inverter-chargers (they charge your battery from shore power). The Inverter Smart is inverter-only. Choose MultiPlus if you use campsites; Inverter Smart if you charge purely by solar and split charge.
Can I add solar to this?
Yes — an MPPT controller and panel run alongside the MultiPlus. Look at the Solar + Power Board kits, or the Full Off-Grid complete system if you want the whole package in one go.
