Higher-energy C&I cabinet ESS

125 kW / 261.2 kWh Battery Storage CabinetMore energy and AC power in the same compact footprint.

A 314 Ah LFP cabinet with 125 kW integrated PCS, 261.2 kWh rated energy and the same outdoor liquid-cooled architecture used across the cabinet platform.

Application fit

Start with the operating duty.

The 125 kW / 261.2 kWh cabinet keeps the compact 1000 x 1400 mm base footprint while using 314 Ah LFP cells and a larger PCS. It is a practical step up when the site needs more peak power and energy without changing the physical cabinet class.

Integrated architecture

Four layers form the starting platform.

The commercial scope still needs a project responsibility matrix covering every external interface.

01

Battery string

3.2 V / 314 Ah LFP cells arranged as 1P260S provide 261.2 kWh rated energy.

02

Power conversion

The 125 kW PCS supports 400 V grid connection with documented overload headroom.

03

Control layer

BMS and EMS provide protection, operating strategy, event records and plant communication.

04

Cabinet systems

Liquid cooling, fire protection, IP54 enclosure and C3 corrosion class support outdoor duty.

Technical specifications

Documented configuration data.

Values are taken from the supplied manufacturer specification. Final purchase, installation and acceptance must use the approved project datasheet, drawings and test documents.

Engineering note: rated energy is not the same as guaranteed usable energy. Confirm SOC window, auxiliaries, ambient derating, ageing and operating reserve.

Buyer questions

Resolve these points before ordering.

Use the answers to narrow the design; use the final project documents to release the order.

What is the difference from the 105 kW / 233 kWh model?

This version uses 314 Ah cells, 261.2 kWh rated energy and a 125 kW PCS while retaining the same documented base enclosure size.

Can it combine solar self-consumption and peak shaving?

Yes. The EMS can coordinate both objectives, but the PV meter, tariff periods, export constraints and minimum reserve SOC need to be defined.

Does the cabinet include the site transformer?

No transformer should be assumed unless it appears in the project scope. The documented cabinet presents a 400 V AC interface.

How is usable duration calculated?

The nominal energy-to-power ratio is about 2.09 hours. Actual dispatch duration uses the approved usable SOC window and project efficiency assumptions.
