The situation
Line crews, substation maintenance, tower service and fibre splicing all run test gear, tools and lighting far from a panel — frequently at night in residential areas where noise ordinances bite.
Utilities carry large capital budgets, are under storm-hardening pressure, and buy in fleet quantities once a unit is on the approved equipment list. The entry is slower than film or events. Once you are in, it is very sticky.

The loads
What one unit runs, and what takes three
These are the loads this vertical actually runs. Most of them are single-phase and a single unit covers them. The three-phase ones are flagged, and they mean a three-unit set — which is a different quote, a different weight and a different conversation, so ask about them early.
- Cable pulling winches, hydraulic pumps and compressors — three-phase ones take a three-unit set
- Substation test sets — hipot, relay test, transformer turns ratio
- Fibre splicing rigs, fusion splicers and OTDR benches, quietly, in a van
- Tower-top lighting and rigging power for overnight service windows
- Comms repeaters, satellite uplink and cell-on-wheels restoration
- Eliminating vehicle idling purely to run an inverter off the truck
Three-phase takes three units. One unit is a single-phase machine — 6 kW, 5.9 kWh, four AC outlets. Its front panel carries a phase selector, so three units set to phase 1, phase 2 and phase 3 and joined by the combining connector will feed a three-phase load at 6 kW a phase. That is three enclosures, three charge states and roughly 90 kg for about 18 kWh. We say so plainly because an earlier version of this site claimed three-phase came out of a single box, and it does not. The three-unit specification →
Why we are better here
The comparison that decides this job.
What you are living with today
- A truck idling all night to power an inverter burns fuel, wears the engine, and is increasingly banned outright
- A tow-behind genset in a residential street at 2 a.m. generates complaints and sometimes fines
- A truck inverter is limited to what the alternator can spare, and the engine has to run to supply it
- Fan noise is small, but it is the difference between a complaint and none
Solida Power in this scenario
- Silent operation is compatible with overnight residential work windows
- 6 kW runs test sets, splice rigs and site lighting with no engine running at all
- Modules ride in a van without a tail lift and get carried to a manhole or a tower base
- No engine hours accrued on the service vehicle
- Fleet telemetry through xPowerOS, which is how a utility tracks anything it owns
Going deeper
Approved equipment lists are the real gate
A utility does not buy the best unit; it buys the unit on the list. Getting onto that list is slow, document-heavy work, and it is also the moat — once you are specified, a competitor has to restart the whole process to displace you.
Storm response is the wedge into the fleet
Storm hardening is where discretionary utility money moves fastest. A pack that supports both routine night work and storm restoration gets funded from two budgets, which is how a pilot becomes a fleet order.
The honest caveat
Publish the peak and 10-second overload figure before you pitch this vertical. Winch and pump starting current is what a fleet engineer will ask about first, and the continuous 6 kW number will not answer them.
Every scenario page carries one. If we cannot name the weakness in a use case, we do not understand it well enough to sell into it.

Film, TV & broadcast
Batteries get placed next to talent, where nothing with an engine can go. 5.9 kWh covers a lighting package for a shift, silently, from a unit a grip can wheel onto the floor.

Emergency services & disaster response
Roughly 85 Americans die each year from portable-generator carbon monoxide, and the toll spikes after every hurricane. A fanless battery that runs indoors is a different category of product to a fire chief.

Defense & expeditionary power
The highest margin and the best fit for the underlying physics. Acoustic and infrared signature reduction is survivability, and field recharging of drone batteries is a large, urgent and badly served load.
