Trailer-mounted storage from 230 to 1,840 kWh delivers temporary, backup and off-grid power.
BRAMPTON — Soneil Spark will debut its Mobile Battery Energy Storage System (Mobile BESS) at RE+ 2026 in Las Vegas, Nov. 17–19. The Mobile BESS is a portable, modular battery storage built into a towable trailer.
“Wherever your business goes, the power goes with it. Simply tow it where energy demand grows,” said Sonya Jain, CEO of Soneil Spark. “Start with one unit and add more as your needs change.”
Per a Nov. 12 press release, the Mobile BESS is built to be towed and to work in any weather.
The company also stated that the Mobile BESS has an automatic fire suppression system at the battery and trailer level; UL 1973, UN 38.3 and UL 1741, and is designed to meet UL 9540A requirements.
Soneil says the Mobile BESS is built for generator and equipment rental, construction, emergency and backup power, utilities, electrical contractors, events, film and entertainment, and off-grid sites such as mining and agriculture, with a hybrid option that also adds EV charging.
