Why Spark BESS
Stored power, ready to deploy anywhere
Purpose-built battery storage: mobile when you need it, permanent when you want it.
Power anywhere, even off the grid
Bring power to remote sites and jobs with no connection at all.
Keep the lights on
Ride through an outage without losing production, refrigeration, or the shift.
Cut the priciest moment off your bill
Store off-peak power and use it at your busiest hour, the one utilities charge extra for.
Mobile today, permanent tomorrow
Tow it to the job this month, bolt it down next year. The same unit does both.
A clean alternative to diesel
Generator power without the fuel runs, fumes or noise. And it starts instantly.
Run it as a test system
Charge and discharge batteries on demand. Customers use the Spark BESS as a mobile test bench.
Charges while it works
The unit charges and discharges at the same time, so solar, a generator or the grid can feed it while it powers the site or charges vehicles.
Units run in parallel
Combine trailers into one system for multi-megawatt-hour deployments.
Inputs and outputs
Plugs into what you have, powers what you bring
In
Grid, solar, wind, generator, or an EV charger.
Out
Camlock, three-phase, 120 V and 240 V receptacles.
Not seeing your setup?
We build to it.
Works with what you have
Takes power from any source: grid, solar, wind, generator, or an EV charger. Start hybrid and cut your generator runtime. Go fully electric when you are ready.
Monitoring
See it from anywhere
Live state of charge, output and alerts on the on-board touchscreen, or remotely over LTE through the Spark CMS.
Quiet enough to work beside
No engine, no exhaust, no vibration, so it runs where a generator would be unwelcome: overnight, indoors, or next to people.

FAQ
Frequently asked questions
What sizes does the Spark BESS come in?
Four standard configurations: 230, 460, 920 and 1,150 kWh. Our engineering team configures capacities above and below the standard range.
Can it run while it charges?
Yes. The unit charges and discharges at the same time, so solar, a generator or the grid can feed it while it powers your site.
How does it move between sites?
It is towable. Hitch it to a standard truck and tow it where the work is. It can also be installed as a fixed unit.
