Shore Power for Van Life: Plug In When You Can
Shore power—connecting your van to a standard 120V AC outlet—is a game-changing addition to any van build. It lets you charge your battery bank rapidly, run high-draw appliances, and skip the solar charging delay on cloudy days. Whether you’re at a campground with hookups, a friend’s house, or a parking lot with an outlet, a shore power setup pays for itself fast. Here’s how to set it up and what to buy.
1. Progressive Industries 30-Amp Shore Power Inlet
A 30-amp inlet port mounted on the exterior of your van lets you plug into standard campground hookups. Progressive Industries makes high-quality inlets with weatherproof covers and robust construction that will last years of regular use.

2. Victron MultiPlus Inverter/Charger
The Victron MultiPlus is the heart of a professional shore power setup. It functions as both an inverter (converts 12V DC to 120V AC) and a charger (converts shore power to DC to charge your batteries). The transfer switch is automatic—it seamlessly switches between shore and battery power.

3. 30-Amp Shore Power Extension Cord

- Amperage: 30-amp (3,600W) is standard for van builds; 50-amp is overkill for most.
- Inlet Placement: Mount on the driver’s side rear for easy access without blocking traffic.
- Surge Protection: Add a surge protector between the inlet and your inverter/charger to protect against campground power spikes.
- Automatic Transfer Switch: Essential for seamless switching between shore and battery/solar power.
- Grounding: Proper grounding of your shore power system is critical for safety.
- Converter/Charger Sizing: Size your charger to top up your battery bank within 4–6 hours of shore power access.
Final Thoughts
Shore power hookup transforms your van into a truly versatile live-in vehicle. On rainy weeks or during stationary work periods, plugging in keeps your system topped up without draining solar reserves. Pair a Victron MultiPlus with a quality 30-amp inlet and you’ll have a system that rivals any RV setup.
Frequently Asked Questions
Do I need 15, 30, or 50 amp shore power?
For a van, 15 or 20 amp is almost always enough. That delivers 1,800-2,400W, which comfortably runs a battery charger, a small heater, and outlets simultaneously. Thirty amp service exists for RVs with air conditioning and multiple appliances. A simple 15 amp inlet also plugs into any household outlet with a normal extension cord.
What do I actually need to install an inlet?
A weatherproof exterior inlet, marine grade cable of appropriate gauge, a breaker panel or at minimum a properly rated breaker, a GFCI outlet or breaker for shock protection, and a transfer arrangement so shore power and inverter output can never be connected together. That last point is the one people get wrong most often.
How does shore power interact with my inverter?
Either use an inverter-charger, which handles the switching internally and passes shore power through while charging, or install a manual or automatic transfer switch. Wiring both an inverter and shore power to the same outlets without a transfer device can back-feed the inverter and destroy it, or energise the shore cord dangerously.
How weatherproof is the exterior inlet?
Choose an inlet with a spring-loaded gasketed cover rated for marine use, and mount it on a vertical surface so water runs off rather than pooling. Seal the mounting flange with butyl or a marine sealant. Most inlet failures are corrosion inside the housing from water tracking down the cable into the connection.
Is it worth adding if I have plenty of solar?
Yes, as insurance. A week of rain, a winter month at northern latitudes, or a stint parked in a friend’s driveway all leave solar unable to keep up. A shore inlet costs 150-300 dollars in parts and lets you fully recharge overnight from any household outlet, which is worth having available.
