US charging station manufacturer Power Up Connect has introduced the MBESS 90 kWh, the result of a three-year collaboration with Dominion Energy, one of the country’s largest utilities.

The unit was unveiled at the CES 2025 show, and is now available for commercial purchase.

The MBESS 90 kWh has a maximum output of 30 kW. At under 5,000 lbs, the mobile battery storage system is light enough to be towed by even mid-sized SUVs and can be safely deployed throughout communities owing to its UL9540 and UL9540A certification.

The unit includes 1.1 kW of solar panels, which can be expanded to 15 kW using an additional solar array for fully off-grid deployments. Users can connect up to 10 units in a daisy chain for a combined 900 kWh of capacity.

A range of output options enables the MBESS to power anything from a standard 120 VAC appliance to an EV.

“We built the MBESS 90 kWh to meet the highest standards. From safety, to reliability to mobility, we know that people will be relying on our system to get them the energy they need in places where there are no other options. It has to work, and our MBESS system delivers,” said Scott Calhoun, COO and President of Power Up Connect.

“The UL certification has been the key to ensuring that our corporate customers can use this system in public settings. That’s what fire marshals and permitting offices are looking for to approve a battery system of this size as the energy solution for those types of deployments,” explained Mwamburi Mkaya, MBESS 90 kWh project director. “Before this system, it’s been the wild west out there in the battery world. There are several options available, but all of them were developed before any standards were in place. Our partnership with Dominion Energy gave us the insight to develop a system that meets the highest safety standards and can be deployed in almost any industry that requires mobile energy.”
