VEHICLE ELECTRICAL SYSTEMS
A reliable electrical system is the foundation of a capable overland vehicle. At White River Overland, we design and install custom electrical system upgrades for vans, trucks, and overland SUVs that are built for off-grid travel. From auxiliary batteries and solar charging to inverters, lighting, and clean power distribution, every system we build is thoughtfully engineered to be safe, serviceable, and tailored to how you actually use your vehicle. Our focus is on balanced, well-integrated electrical solutions that perform consistently in remote environments and adapt as your needs evolve.
Why Upgrade Your Vehicle’s Electrical?
-
Reliable Power Off the Grid
Factory electrical systems are not designed to support sustained accessory use. Upgrading your electrical system ensures consistent, dependable power for fridges, lighting, and devices when traveling off-grid or away from shore power.
-
Safe Power Distribution
Improper wiring is one of the most common issues in overland vehicles. A professionally designed electrical system uses proper fusing, grounding, and cable sizing to reduce risk, protect components, and ensure long-term safety and reliability.
-
Support Overland Accessories
From refrigeration and communication gear to camera equipment and tools, modern overland travel demands more from a vehicle’s electrical system. Upgrades allow your vehicle to safely support these loads without stressing factory components.
-
Enable Solar and Auxiliary Charging
An upgraded electrical system allows you to integrate solar charging, DC-to-DC charging, and shore power in a controlled, efficient way. This keeps batteries topped off while driving, parked, or camped without relying solely on the engine battery.
-
Improve System Efficiency
Well-designed electrical systems balance loads, charging sources, and battery capacity more effectively. This improves overall efficiency, reduces unnecessary cycling, and helps extend the lifespan of batteries and electrical components.
-
Future-Proof Your Vehicle
Electrical upgrades make it easier to add accessories or expand your system over time. By building in capacity and serviceability from the start, your vehicle can evolve with your travel style without requiring major rewiring down the road.
Auxiliary Battery Systems, 12V & 48V Power Platforms
Auxiliary batteries are the core of any overland electrical system. At White River Overland, we design and install 12-volt and 48-volt electrical systems based on how your vehicle is used, the loads you plan to run, and how long you travel off-grid. From compact dual-battery setups to higher-capacity 48V systems commonly used in Sprinters and larger builds, we focus on proper sizing, safe installation, and long-term reliability. Each system is designed to integrate cleanly with your vehicle while supporting future expansion.
Solar Charging, Dc-to-DC Charging & Shore Power Integration
Reliable charging is just as important as battery capacity. We integrate solar panels, DC-to-DC charging, and shore power into balanced systems that keep batteries charged whether you’re driving, parked, or plugged in at camp. Our approach prioritizes efficient charge management, proper regulation, and clean wiring so power flows seamlessly between charging sources without stressing components or creating failure points.
Overland Lighting & Accessory Power
A well-designed electrical system supports everyday usability as much as off-grid endurance. We install interior and exterior lighting, 12V and USB charging, AC outlets, inverters, and accessory circuits to power fridges, communications gear, devices, and camp accessories. Power distribution is laid out intentionally, with proper fusing and circuit protection, ensuring systems are easy to understand, service, and expand. For customers who prefer modular solutions, we also integrate portable power stations where appropriate, while ensuring they work safely within the overall electrical setup.

ABEONA
The Abeona custom van was designed to be comfortable even on extended trips. It is loaded with creature comforts, like a stowable shower and a high-end kitchen complete with induction cooktop and coffeemaker. It’s powered by the SAGA 4V power system with a 9.6kW battery bank and 270W solar power, so it remains functional even for extended off-grid trips, and the advanced climate control system means it can be used all year round.

Wolf Den
The Wolf Den was designed to be a 4-season van for camping, skiing and cross-country trips. It can comfortably seat and sleep three passengers without feeling crowded. We particularly love the Bamboo paneling and Baltic Birch custom cabinets on this van build, and there is loads of storage incorporated into the design for gear and supplies.

Zen Den
The Zen Den was created for a family who wants to enjoy the best of both indoor and outdoor living while on camping adventures. We managed to get 5 sleeping spaces into the van by incorporating a rooftop tent and folding bench seat. The layout is highly configurable and slide-out rear kitchen saves space while allowing them to cook outdoors.

Meili
This van was designed for an active couple who loves skiing, so it was important that the van was equipped for icy roads and sub-freezing conditions. In addition to a fantastic heating and suspension system, the van has features like frost-proof plumbing so they can take a hot shower after adventures.
