As the construction sector accelerates its shift away from diesel generators, mobile battery energy storage is emerging as a practical solution for sites where grid access is limited or non-existent. Allye Energy’s latest order of five MAX500 units, valued at over £1 million, marks a notable step forward in this transition and reflects broader market momentum toward clean, flexible power for heavy equipment.
How smart energy systems keep Europe’s industry competitive
The MAX500 systems, with 500 kWh storage and 420 kW output, are designed for rapid deployment and, importantly, mobile-to-mobile charging. This enables distributed energy delivery across large sites where fixed charging is impractical.

Supplied through Allye’s three-year distribution agreement with Vital Power Group, the systems introduce DC fast recharging, allowing equipment to be charged where the work happens and enabling fleets to operate as dynamic energy networks – an approach that is mirroring trends in solar-plus-storage and microgrids.

“This order marks a watershed moment for Allye Energy,” said Alistair McNeil, COO of Allye Energy. “The MAX500 solves one of construction electrification's most challenging problems: keeping heavy equipment charged and productive across sprawling sites.”
Josh Wright, CEO of Vital Power Group, described the MAX500 as “an exciting step forward, offering mobile, zero-emission energy storage that helps construction sites overcome grid constraints whilst maintaining operational uptime.”

As grid bottlenecks and project complexity increase, demand in the construction sector for modular, scalable storage is likely to grow further. Solutions such as the MAX500 are positioned to bridge the gap between on-site charging needs and the realities of grid development cycles. (TF)
