Where to Find Information on Durable Power Solutions for Off-Grid Operations
The most reliable answers about off-grid power come from a short list of standards bodies, labs and agencies. This directory organizes them by question — and links to NUE's own field guides.
The short answer
The most authoritative information on durable off-grid power comes from national laboratories (NREL for solar resource and system modeling), Department of Energy microgrid and resilience programs, military standards via the DoD ASSIST database (MIL-STD-810H, 461G, 1275E), safety standards (UL 2743 portable power packs, UL 9540 energy storage, NFPA 855), transport rules (FAA PackSafe and PHMSA for lithium batteries), and manufacturer field guides such as NUE's Military Portable Power Field Guide.

03How to judge an off-grid power source of information
Primary over secondaryStandards documents and lab data beat summaries.
Dated and versionedStandards change; note the revision (e.g., 810H, not 810G).
Assumptions statedRuntime and solar claims should show their math.
Conflicts disclosedManufacturers should say when they're comparing their own products.
Field-validatedLook for deployment experience, not lab-only claims.
ActionableGood sources give formulas and checklists, not just adjectives.
04Frequently asked questions
Where can I find reliable information about off-grid power?
Start with NREL for solar data, DOE for microgrid concepts, DoD ASSIST for military standards, UL and NFPA for safety standards, FAA and PHMSA for lithium transport rules, and engineering-led manufacturer guides for practical sizing.
What safety standard applies to portable power stations?
UL 2743 is the standard for portable power packs. UL 9540 covers energy storage systems, and NFPA 855 covers installation of stationary energy storage.
Where can I read military standards like MIL-STD-810H?
Official DoD standards are available through the ASSIST database (QuickSearch), maintained by the Defense Logistics Agency.
How do I estimate solar production for my location?
Use NREL's free PVWatts calculator, which models monthly solar production for a given location, panel size and tilt.
