Radios, satellite terminals and laptops have become as essential as ammunition. As the U.S. Army puts it, they are “rendered ineffective without a reliable energy source.” According to NATO’s analysis, a front-line company running drones, radios and a medical post may need 20–30 kWh of electricity a day.

Producing that energy with fuel creates two risks: a generator that can be heard and seen, and a fuel supply that has to be delivered. The report recommends treating electricity “as a parallel class of supply” and calls for “silent power discipline.”

The SUNS Energy Hub is built for exactly that. It keeps communications running silently on stored solar power. When a generator is still needed, automatic generator control runs it only when necessary, which cuts fuel use, noise and generator wear.
