Power built for
where the road ends.
A Utah Valley-based company helping overlanders build premium solutions to their overland electronic needs — engineered to hold up off-grid, not just on paper.
Three ways to build your electrical system
Pick the package that fits your trip. Each one is a complete electrical rework for an existing overland build. Not sure which fits? Start with a consulting session.
Foundation
The strong foundational base for an existing overland build, ready to grow with you.
- Battery-to-battery DC-DC charger (BCDC) charging your auxiliary battery from the alternator
- Dual battery system with the starter and auxiliary batteries isolated and protected
- Battery management and monitoring, with a live state-of-charge readout
- Fused distribution panel with open, labeled circuits ready for accessories
- Correctly sized cable, breakers and terminations, labeled and documented
Trail
Everything in Foundation, plus the power and charging to live off-grid for days.
- Everything in Foundation
- Roof-mounted solar with an MPPT controller feeding the auxiliary battery
- Larger lithium auxiliary battery bank sized to your actual loads
- Dedicated 12V fridge circuit plus switched circuits for lighting, USB and accessories
- Inverter for 120V AC when you need it
Expedition
A complete electrical rework, built and proven for a worldwide overland trip.
- Everything in Trail, sized up for extended remote travel
- Redundant charging from the alternator (BCDC), solar and shore power, so one failure never strands you
- Remote battery and system monitoring with fault alerts
- Full harness rebuild with protected, serviceable routing, plus a spare fuse and parts kit
- Load-tested and documented before you leave, with wiring diagram and owner's guide
Built where we play
Utah's canyons, fall-color mountain roads and desert slickrock are the test bench. Every system is designed around trips like these.





Why Ponderosa
We design for the trip that doesn't go as planned — where reliability matters more than a spec sheet.
Built for the terrain
Every system is designed around the vibration, temperature swings, and power demands of real overland travel — not a showroom.
Systems that work together
Electronics, solar, and refrigeration are designed as one power ecosystem, not separate parts bolted together after the fact.
Straightforward to install
Clear documentation and sensible layouts, so you spend your time on the trail instead of troubleshooting wiring.
