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.

PWRNXT PX-125 all-in-one 3-in-1 integrated design — PCS, BMS and HV-Box combined, 99% max efficiency, 8,000-cycle life, 314Ah LFP A+ grade cells
PWRNXT PX-125 24/7 all-round safety protection across six categories — cells, electrical, fire, environmental, structural, and data, including 80% lower thermal runaway risk, 3-level fire suppression, IP67/IP66/IP55-C5 ratings, and end-to-end cloud encryption

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.

Cells Electrical Fire Environmental Structural Data

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.

10 Units Parallel 193.3 kWh/m² 40% Lower Install Cost 60% Faster Commissioning

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.

PWRNXT PX-125 units connected in series for multi-MWh capacity — supports 10 units in parallel, 1.35 square metre footprint per unit, 193.3 kWh per square metre energy density, factory-preconfigured cabinet transport

Four configurations from a 125 kW indoor cabinet to a 5 MWh hi-cube container — every unit on a fixed quarterly OpEx lease with zero upfront capital and PWRNXT's contractual 98.5% uptime SLA.
