Products Description
Complete off-grid power packages engineered for the roughest terrain on earth. Each kit includes a shock-rated battery bank, MPPT solar controller, pure sine wave inverter, and marine-grade cabling - tested to survive 100,000 km of corrugated gravel road without a single connector failure.
IP67 Sealed Kit MIL-SPEC Shock Rated Complete Package Plug-and-Play Wirin
Lithium Ion Battery for RV Solar
Torphan's vibration-proof RV
Off-road adventurers and overland professionals need power systems that survive what standard batteries simply cannot: relentless vibration, dust infiltration, temperature extremes, and mechanical shock from rock strikes and water crossings. Torphan's vibration-proof RV solar kits address every one of these challenges with purpose-engineered components rather than adapted stationary designs.
Each kit ships as a complete, pre-configured package - the battery bank arrives with internal dampening mounts already installed, the MPPT controller features conformal-coated PCBs rated for 95% humidity environments, and all interconnecting cables use MIL-DTL-38999 circular connectors that cannot vibrate loose regardless of terrain severity. Marine-grade tinned copper wiring with silicone jacketing withstands -55°C to 200°C continuous temperature exposure without cracking or embrittlement.
Available in four voltage/capacity tiers covering 12V/100Ah through 48V/200Ah, each kit is matched to typical solar array sizes from 200W to 1200W. Installation requires only basic hand tools - every connection uses color-coded, polarity-protected connectors that physically cannot be misconnected. An illustrated quick-start guide tailored to popular RV platforms (Sprinter, Transit, Ducato, Land Cruiser) ships with every kit.
Engineered for the End of the Road
Three structural innovations define our vibration-proof platform.
Triple-Layer Anti-Vibration Architecture
Internal cell stack floats on elastomeric isolators, the pack enclosure mounts through rubber-grommeted brackets, and all PCB assemblies use conformal coating plus mechanical potting at stress points. This triple isolation approach attenuates vibration transmission by 94% compared to rigid-mount designs.
IP67 Hermetic Sealing
Gasketed enclosure with Gore-Tex pressure equalization vents maintains IP67 rating even during high-pressure hose-down or river crossing submersion. Internal desiccant cartridge absorbs residual moisture to protect electronics in tropical humidity environments.
Arctic-to-Desert Thermal Range
Wide-electrolyte formulation maintains 85% rated capacity at -30°C discharge and operates without thermal derating up to 60°C ambient. Integrated heating elements activate below 0°C to protect cells during charging in cold conditions.
Built for Extreme Mobile Environments
Where standard batteries fail, our vibration-proof kits deliver reliable power.
Safari & Expedition Vehicles
Multi-week African bush expeditions demand equipment that survives corrugated tracks and dust storms. IP67 sealing prevents fine particle intrusion, while vibration isolation protects cells from constant rough-road hammering at 40 km/h.
Rally Raid Support Trucks
Competition support vehicles carrying diagnostic equipment and communication systems need unshakeable power. MIL-spec shock rating of 150G half-sine ensures continued operation through jump landings and rock impacts.
Marine Live-Aboard Cruisers
Sailors and powerboat cruisers face constant motion, salt spray, and hull vibration. The IP67 sealed enclosure and corrosion-resistant terminals handle marine environments that would destroy conventional battery installations within months.
Technical Specifications
Each kit includes battery bank, MPPT controller, inverter, cabling harness, and mounting hardware. All components are vibration-rated as a matched system.

Frequently Asked Questions
Q: What makes these kits 'vibration-proof' compared to standard lithium batteries?
A: Three engineering layers differentiate our kits: (1) Internal cell modules float on elastomeric isolators that absorb 94% of vibration energy before it reaches the cells; (2) the pack enclosure uses rubber-grommeted mounting brackets instead of rigid bolts; (3) all electronic assemblies receive conformal coating plus mechanical potting at solder joints. This triple approach is validated by 50,000 km of simulated corrugated road testing with zero failures.
Q: Can I install the kit myself without professional help?
A: Yes - every kit is designed for DIY installation by the RV owner. Color-coded connectors physically prevent incorrect wiring. The included illustrated guide shows step-by-step installation specific to your vehicle platform. Basic hand tools (socket set, screwdriver) are all that's required. Typical installation takes 2–4 hours for a competent DIYer.
Q: What solar panel wattage is needed to fully charge the battery daily?
A: As a general rule, plan for solar wattage equal to 2–3× the battery capacity in kWh. For the VPK-1210 (1.28 kWh battery), 200–300W of panels provides full recharge in 4–6 peak sun hours. For the VPK-4820 (20.48 kWh), 800–1200W is recommended. Actual performance depends on geographic latitude, season, and cloud cover.
Q: How does the kit handle operation during river crossings or heavy rain?
A: The IP67-rated battery enclosure withstands temporary immersion up to 1 meter depth for 30 minutes. Gore-Tex pressure equalization vents prevent vacuum lock during altitude changes while blocking water and dust ingress. All external connections use sealed MIL-spec circular connectors rated IP68 when mated. The kit is designed to continue operating after complete water submersion and drying.
Q: Is there a communication interface to monitor battery status while driving?
A: Yes - each battery includes Bluetooth 5.0 connectivity to the Torphan RV mobile APP (iOS and Android). The APP displays real-time state-of-charge, current draw, cell temperatures, and solar input power. Historical data logging helps you optimize your daily energy management. An optional CAN bus adapter enables integration with vehicle dashboard displays in custom builds.
