01
4.3 kW Bifacial Solar
Six 710-watt bifacial panels unfold from the trailer. Bifacial panels can collect light from both sides, helping capture additional reflected sunlight when conditions allow.
PORTABLE SOLAR + BATTERY POWER
Bring serious electrical power almost anywhere.
LoadRunner is a self-contained power station on a trailer. It combines a large bifacial solar array, high-capacity batteries, 20 kW of 240V Split-phase AC output, and dual-fuel generator backup in one towable system.

WHAT IS LOADRUNNER?
A towable power station that can run real equipment.
Think of LoadRunner as a large battery power station built into a rugged trailer, with its own deployable solar panels and a generator for backup.
During normal use, your equipment runs quietly from the batteries. The solar panels recharge the batteries whenever sunlight is available. If the batteries get low or the weather stays poor, the onboard generator can recharge the system so it can keep working.
It is designed for places where utility power is unavailable, unreliable, too expensive to bring in, or simply inconvenient.
DEPLOYED IN MINUTES
A complete portable power source without assembling a pile of separate equipment.
CORE SYSTEM
Large enough for demanding loads. Simple enough to use without being a power-system expert.
02
45 kWh Battery
Large lithium iron phosphate battery storage provides quiet operation at night, during cloudy weather, and whenever you do not want a generator running.
03
20 kW 240V Split-phase Power
Provides standard 120V power plus 240V Split-phase output for larger equipment, with enough inverter capacity for tools, pumps, HVAC equipment, communications gear, appliances, and other serious loads.
04
Propane + Gasoline Backup
The onboard generator can run on propane or gasoline. Propane is well suited to emergency readiness because it stores for long periods and supports clean-running standby use. Gasoline is useful when the generator will be run more often and fast, familiar refueling from cans or local fuel stations matters.
Need more solar while staying in one place?
A separate ground-mounted solar array can be connected when LoadRunner will remain deployed at one location for an extended period, increasing available solar collection without changing the trailer-mounted array.
OPTIONAL EQUIPMENT
ADDITIONAL COST
Mast / Tower Package
An optional mast or tower can be mounted at the front of the trailer for equipment such as scene lighting, loudspeakers, cameras, antennas, radios, wireless networking, or other communications hardware.
This turns the trailer into more than a power source—it can also become a temporary elevated platform for lighting, observation, and communications equipment.
ADDITIONAL COST
Integrated Smart EV Charger
An optional integrated EV charger can be configured with power-saving rules so vehicle charging does not unnecessarily drain the LoadRunner battery.
For example, charging can be allowed only when surplus solar is available, limited to a selected power level, paused below a chosen battery state-of-charge, or scheduled for times when other trailer loads are low.
SIX FULL-SIZE BIFACIAL PANELS
More collection area when you need it. Compact when you do not.
WHERE IT FITS
Portable power for places where the utility grid is too far away, unavailable, unreliable, or down.
Your loads can still connect to LoadRunner with normal heavy-duty extension cables and distribution equipment—the difference is that the trailer brings the power source to you instead of requiring a nearby building, utility service, or continuously running generator.
BUILT IN UTAH
Designed, engineered, and built in Layton, Utah.
LoadRunner is designed and built by FoxFab Laser in Layton, Utah. FoxFab Laser is a veteran-owned fabrication company with in-house laser cutting, forming, welding, fabrication, and finishing capabilities.
That means the trailer is being developed by the same team that fabricates the structure, solves the mechanical details, and supports the product.
