Why liquid cooling instead of air cooling?

Intelligent liquid cooling improves heat dissipation by 40%+ over air and holds the cluster temperature spread to just 3 °C, which means longer cycle life, higher efficiency and a compact 1.35 m² footprint.

Is the cabinet certified for the European grid?

Yes. The 261 kWh system is certified to the Italian grid codes CEI 0-16 and CEI 0-21 by TÜV NORD, and KONJA products carry IEC 62619 (battery safety) and IEC 62477 (PCS safety) from TÜV SÜD.

Which applications is it best suited to?

Commercial & industrial peak shaving and demand-charge reduction, PV self-consumption, backup power, and time-of-use arbitrage — from a single cabinet up to multi-unit microgrids.

Does it include energy management and monitoring?

Yes. A built-in EMS with cloud platform provides remote monitoring, data analytics and revenue calculation, with AI-optimised dispatch across applications.

Applications

Where the 125kW / 261kWh Liquid-Cooled Cabinet delivers value.

Peak shaving & demand charges

Cap site demand and shave evening peaks to cut demand charges and time-of-use costs.

PV self-consumption

Store surplus rooftop or ground solar and discharge it after sunset to raise self-consumption.

Backup power

Keep critical loads running through grid outages with fast, seamless switchover.

Energy arbitrage

Charge off-peak and discharge on-peak to arbitrage time-of-use tariffs.

Microgrid

Parallel up to 12 units to build robust local microgrids.
