A 10ft-class buffer wherever diesel meets load

Compact liquid-cooled storage beside the genset - cut fuel waste, ride shock loads, keep critical loads online. Reference cabinet: tier-one partner TRENE-P500B1044L-2H (~500 kW / 1044 kWh). Also ties to PV and other site sources.

Why a buffer

Fuel and capacity buffering - not a marine BESS story

Wherever diesel (or weak grid) meets impact loads, a compact liquid-cooled cabinet absorbs peaks, fills valleys, and keeps critical loads online. Broad push for diesel, PV, storage and integrated energy-system customers.

Pain points

Sets idle or run oversized - fuel waste on temporary and remote sites.
Cranes, welders, pumps and compressors create shock loads that trip small transformers.
Pure container BESS pitches miss the job: buffer beside diesel / PV / weak grid - not Expo megawatt standby competition.

Co-brand path

Tier-one partner PCS / EMS / BMS liquid-cooled cabinet as the power electronics + battery platform.
CIMC ENRIC overseas sales, scheme, and enclosure/integration when the project needs the box.
Honest line: datasheet numbers are the reference platform; final scheme follows site load profile.

Two scenarios

Diesel-storage microgrid | Weak-grid boost

Same cabinet class; different site logic. Scheme-first - share load curve and fuel/source before we lock a SKU.

A. Diesel-storage microgrid

Pair the buffer with on-site diesel. Charge on low load so the genset stays in its efficient band; discharge on peaks so you can avoid oversizing and burn less fuel. PV can join the same bus where the site allows.

B. Weak-grid / transformer boost

When transformer capacity is short, the buffer supplements heavy loads and rides through impact. Optional peak-shaving where tariffs apply.

Datasheet PDF: upload pending on site - full AC/DC/system tables are on this page from the partner TRENE V1.0.
Scheme-first: ask for load profile, fuel/source and site conditions before locking SKU, parallel count or delivery. Datasheet figures are the partner reference platform - not invented kW and not a commercial offer by themselves.
