Deployable vs. Fixed-Site Power: What Changes

Compliance reviewed by Onur Oncer, SDVOSB Materials compliance lead.

A deployable power system is a fixed system that also has to survive being moved. HUBZone Equipment, the energy division of SDVOSB Materials Technology & Supply LLC, sees three things change the moment a requirement goes mobile: lithium transport qualification under Title 49 of the Code of Federal Regulations, environmental test evidence from the MIL-STD-810 family of military standards, and the enclosure hardware that makes repeated setup possible.

Same Equipment, Different Qualification Package

A deployable unit and a fixed installation can carry the same battery modules, the same inverters, the same controls. What separates them is the set of documents the equipment travels with, and the fact that a mobile unit gets handled, energized and torn down by people who did not build it.

Our energy storage and microgrid guide for federal facilities covers the architecture for a system that gets sited once and stays there. This post covers what a statement of work adds when the same capability has to be trucked, shipped or flown, stood up by a crew on site, then moved again.

Lithium Transport Qualification Is a Document, Not a Shipping Detail

The Hazardous Materials Regulations treat lithium cells and batteries as hazardous material. Under 49 CFR 173.185, Lithium cells and batteries, each lithium cell or battery must be of a type proven to meet the criteria in Part III, sub-section 38.3 of the United Nations Manual of Tests and Criteria. The section is explicit that a battery is subject to those tests whether or not its cells were already of a tested type.

Buyers skip the paperwork half. The same section requires each manufacturer and each subsequent distributor of lithium cells or batteries manufactured on or after January 1, 2008 to make a test summary available, including the manufacturer's name and contact information. That summary is the artifact to ask for at quote time, not the one to go looking for at a loading dock.

Air movement narrows things further. State of charge limitations for lithium ion shipped by air sit in special provision A100, referenced from the hazardous materials table at 49 CFR 172.102, and packages can require a CARGO AIRCRAFT ONLY label as specified at 49 CFR 172.448. If the concept of operations includes an airlift, put it in the requirement. A unit shipped at working charge and a unit shipped under a charge limit are not the same delivery.

MIL-STD-810 Describes a Tailoring Process, Not a Grade

Requirements often read "MIL-STD-810 compliant" and stop. The standard says that phrase means very little. MIL-STD-810, Environmental Engineering Considerations and Laboratory Tests, states in its own scope that it does not impose design or test specifications, and that it instead describes an environmental tailoring process producing test methods based on how the materiel will actually be used.

The useful requirement names the environment, not the standard. Vibration for the transport mode the unit will see. Temperature range for the theater or the region. Humidity, sand and dust, altitude, shock off a rough road. Methods get selected against that, and the deliverable is a report saying which methods ran at which severities. A compliance claim with no method list is not something a contracting officer can evaluate.

What a Mobile Requirement Adds to the Scope

Five additions, each written the same way: the item first, then what it obligates the supplier to deliver.

Transport qualification and shipping papers. The UN 38.3 test summary, the shipping description, packaging, marking and labeling for each mode the unit will move by. Name the modes, because road, sea and air are not priced the same.
Environmental test evidence. A report naming methods and severities, tied to the environment you wrote into the requirement rather than to a generic claim on a cut sheet.
Enclosure and handling hardware. Lift points, forklift pockets, tie-down provisions, door swing and access clearance, and an ingress rating suited to being parked outdoors rather than installed in a mechanical room.
Setup and teardown by the using unit. Cable lengths, connector types, grounding provisions, and a procedure a soldier or facilities technician can follow without the integrator standing there.
Sustainment away from the shop. Spares, special tools, and a service model that assumes the unit is nowhere near the manufacturer when something fails.

What Going Mobile Does Not Change

Chemistry selection is the first thing people expect to change and it usually does not. The tradeoffs between lithium iron phosphate and lead acid follow duty cycle, thermal behavior and fire protection review, and those drivers travel with the equipment. A unit does not get a different chemistry because it has wheels under it.

Connection is the second. A deployable system that ties into facility distribution inherits the same interconnection, transfer and anti-islanding questions a permanent installation has. Moving the enclosure does not move that conversation, which is why the architecture in backup power for federal mission-critical facilities still applies once the unit is parked and connected.

Deployable is also not automatically the better answer. A system that will sit on one pad for its entire service life is paying for ruggedization it will never use. If the site is permanent, specify permanent. We would rather say that during the requirement conversation than after the award.

Where This Division Fits

HUBZone Equipment supplies mobile and modular power alongside fixed energy storage and microgrid systems, quoted as one package with controllers, switchgear, distribution, fire suppression and inverters rather than as loose components. The SafeTech Lithium systems this division supplies are built by MUTANT INC. in Virginia with American labor and materials, which keeps domestic content and transport documentation with one manufacturer. Energy past performance includes the Department of Defense, the Defense Logistics Agency, the Department of Energy, the US Army National Guard and the Department of Veterans Affairs.

Frequently Asked Questions

Does the UN 38.3 requirement apply to batteries we already own?

The requirement at 49 CFR 173.185 attaches to the cell or battery type, not to a purchase order, so a battery built to a qualified type stays qualified as it moves. What you need in hand is the test summary the manufacturer and distributor must make available. Ask for it before the unit ships.

Is "MIL-STD-810 tested" the same as certified?

No, and neither phrase carries much weight alone. MIL-STD-810 states that it does not impose design or test specifications; it describes a tailoring process that selects methods for a specific use environment. No certification body issues a pass. Ask for the test report, the methods run and the severities used.

Can a deployable power system be flown into theater?

That depends on the configuration and the state of charge it ships at. Air transport of lithium ion brings in the state of charge limitations at special provision A100, referenced from 49 CFR 172.102, and can require cargo aircraft only labeling. Name the transport modes in the requirement so the shipping configuration gets priced rather than discovered.

Do we need a different battery chemistry for a mobile unit?

Usually not. Chemistry follows runtime, thermal environment, platform loading and the fire protection review, and those drivers do not change because the enclosure moves. What changes is the vibration and shock the mounting and the battery management wiring have to survive.

Are you on the General Services Administration (GSA) Schedule?

No, and we say so plainly. SDVOSB Materials Technology & Supply LLC does not hold its own GSA Schedule. Where GSA is required, orders run through GSA-registered partner vendors. The company does hold The Interlocal Purchasing System (TIPS) contract 230701, often the faster cooperative path for state and institutional buyers.

How do we verify your certifications?

Two checks, neither requiring a call to us. The company's Small Business Administration (SBA) Small Business Search profile lists every active credential, including SBA HUBZone, SBA-certified Service-Disabled Veteran-Owned Small Business and Small Disadvantaged Business. A System for Award Management (SAM.gov) lookup against Unique Entity Identifier K39HBMPLN4B3 confirms active registration and the registered North American Industry Classification System codes.
