Submersible pump
The most dramatic use is powering a pump that drafts water from a pool or approved water source.
Vehicle-to-Load emergency power
The EV is not just a vehicle. It is a mobile power station.
SolarFireTruck.com focuses on the emergency value of EVs with Vehicle-to-Load capability: clean, mobile power that can support pumps, lights, cameras, radios, small tools, and neighborhood readiness equipment when planned safely.
The V2L idea
Stored battery power can move from the road to the emergency scene.
Vehicle-to-Load means the EV can provide power to external devices. In the SolarFireTruck concept, that outside power can support a properly rated submersible pump, camera, lighting, communications, or control equipment.
- Use only equipment within the EV’s rated V2L output.
- Plan for pump startup surge, not just running watts.
- Keep cables, outlets, and connectors dry and protected.
- Use proper GFCI/RCD protection where required.
- Never let emergency equipment block firefighter access or evacuation routes.
What V2L could support
Pumps first. Then visibility, monitoring, and communication.
In a fire-readiness context, power priority matters. The EV should not be treated as unlimited power. It is a limited emergency resource that must be managed carefully.

Camera system
Cameras can help monitor embers, smoke, fences, eaves, and defensive spray areas.

Emergency lights
Lighting helps neighbors move safely, check equipment, and avoid panic in smoke or darkness.

Comms and controls
Radios, phones, routers, controls, and sensors may be small loads but important readiness tools.
Load discipline
The first engineering question is not “Can it plug in?” It is “What is the real load?”
A pump may draw much more power at startup than it does while running. Long cable runs, undersized cords, heat, water exposure, and overload conditions can create serious hazards.
Know the rated output
V2L outlets have limits. The system must be designed around the EV’s actual voltage, wattage, duty cycle, outlet type, grounding behavior, and manufacturer instructions.
Know the pump demand
Pump selection must account for startup surge, running current, head pressure, flow rate, hose length, intake design, and expected operating time.
Know the emergency priority
In a limited-power emergency setup, the pump usually comes first. Lights, cameras, radios, and controls should be planned as secondary loads.
Dual-use fleet value
Postal trucks and municipal EVs could become neighborhood resilience assets.
The key SolarFireTruck example is the electric postal truck: it already travels neighborhood streets, already carries battery power, and could be imagined as a dual-use emergency platform if equipped and governed properly.
Dual-use mail truck
The everyday delivery vehicle becomes a visible emergency power resource during wildfire risk.
Neighborhood fire support
V2L power can support local readiness without pretending to be a professional fire engine.
Fleet resource layer
One vehicle is useful. A mapped fleet becomes a distributed emergency resource layer.
Critical safety boundary
V2L fire readiness must not become unsafe improvisation.
Water, smoke, panic, darkness, batteries, long cords, motors, and fire conditions are a dangerous mix. Real systems need professional electrical design and clear operating rules.
Do not improvise: Do not run random extension cords through wet areas, overload EV outlets, bypass electrical protection, energize unsafe equipment, block emergency access, or stay behind when evacuation is ordered.
Before deployment
The plan must be made before the smoke arrives.
The SolarFireTruck concept is strongest as a planning tool. Identify the vehicle, output rating, safe parking location, cable route, pump load, water source, spray point, and emergency authority before a fire.
- Confirm the EV power rating. Know the voltage, wattage, outlet type, duty cycle, and manufacturer limitations.
- Match equipment to the rating. Pump, camera, lights, and controls must fit the available output with margin.
- Design dry cable routes. Keep electrical connections away from pools, spray zones, trip hazards, and hot surfaces.
- Stage without blocking access. Firefighters, engines, hydrants, gates, driveways, and evacuation routes must remain clear.
- Train responsible operators. A system that no one understands becomes a liability during an emergency.
Next: connect EV power to water.
V2L power is only one part of the system. The next question is how pool water can be drafted, filtered, pumped, and delivered safely.
