Backup Power,
Engineered to Scale
From a single PX-125 cabinet to a stacked, parallel array — the same 5-year hardware warranty, the same Tier-1 cells, at any scale.
One Unit, Every Environment
The same PX-125 cabinet holds up at an EV charging hub, a warehouse, a campus, a commercial building, an industrial park — and keeps delivering power even when the sun doesn't cooperate.
All-in-One Design, 3-in-1 Integrated
PCS, BMS, and HV-Box combined into a single enclosure — smart temperature control and cluster-level battery management built in from the factory.
One integrated unit — no separate PCS, BMS, or HV-Box to source, wire, or maintain. Built on 314Ah LFP A+ grade cells rated for 8,000 cycles, with up to 99% peak efficiency.
24/7 All-Round Safety Protection
Six independent layers of protection — from the cell up to the cloud — so no single point of failure can become an incident.
80% lower thermal runaway risk at the cell level, a 3-level fire suppression system (pack + container + water), enclosure ratings up to IP67, and end-to-end cloud encryption on every connected unit.
MWh-Level Flexible Energy Capacity
Every PX-125 is designed to stack — arrive pre-integrated from the factory and run in parallel for MWh-scale sites without a custom engineering exercise.
Units connect in parallel — up to 10 in a single array — at just 1.35 m² of footprint each. Every cabinet ships pre-integrated from the factory, cutting field installation costs by 40% and commissioning time by 60%. Need more than an array of PX-125s can cover? That's exactly what PX-Cluster is built for.

Not a broker. Not a reseller. A fully integrated engineering operator with contractual skin in the game.
Performance Assurance
A 5-year warranty on Li-ion modules, PCS, and BMS — guaranteed to hold 90% usable capacity or 8,000 cycles, whichever applies, for the full warranty term.
Managed Care
Monitoring is table stakes. We write performance into the contract — and back it with a team that acts before you notice a problem.
