POWRBANK MAX Now Delivers Zero-Transfer-Time UPS Protection and CSA Listing to UL 9540

POWR2 has begun shipping the next generation of POWRBANK MAX. Mobile battery energy storage systems like the POWRBANK MAX give operators a quieter, cleaner alternative to diesel generation, without the fuel logistics, while still delivering the continuous output and dispatchable scale a job site or fleet actually needs. Each unit delivers 250 kVA of continuous output and 500 kWh of usable energy, with parallel capability across up to 10 units for 2.5 MVA / 5 MWh of power and energy storage from a single deployment. These MAX units operate under POWR2’s proprietary ADVANTAGE energy control platform, giving authorized users full remote monitoring and control from any browser.

The new generation is built on true double-conversion architecture, delivering uninterruptible power with a 0.0 millisecond transfer time. There’s no switchover moment between sources. Output is generated continuously by the unit’s own inverters rather than passed through from whatever’s feeding it. That same architecture accepts virtually any input frequency and maintains a stable 60Hz output, with power factor corrected to 0.98, keeping the source and the load fully isolated from each other’s distortions.

The next generation of MAX units are CSA Listed to UL 9540 for the U.S. and Canada, a credential that expands POWRBANK MAX eligibility across North American commercial, federal, and regulated procurement processes.

These credentials open the door to a wider range of deployments, from construction sites with high transient loads to telecom and data backup to large-scale events, hybrid genset displacement, and international sites where incoming power frequency can’t be guaranteed.

Key Specifications

• 250 kVA continuous output, 500 kWh per unit
• True double-conversion UPS protection, 0.0 ms transfer time
• Accepts virtually any input frequency, maintains a stable 60Hz output
• Power factor corrected to 0.98
• Parallel capability up to 10 units (2.5 MVA / 5 MWh)
• CSA Listed to UL 9540 for the U.S. and Canada
• ADVANTAGE remote monitoring and control via secure portal

The ADVANTAGE platform gives authorized users full operational control of each unit, whether they’re standing in front of it or a continent away. POWR2 service teams can remotely access a unit’s internal systems, including the BMS, PCS, HVAC, and PLC, from any cellular-connected site, reducing dispatch requirements and accelerating field response.

These next generation units have already proven themselves under pressure. Five POWRBANK MAX units powered the F1 Canadian Grand Prix in Montreal, handling peak loads of 1.1 MW with zero downtime across 168 hours. See the full case study.
