KuBank 3.0 / 2.0 — commercial and industrial cabinet BESS 277–940 kWh
Country: Canada · Model: KuBank 3.0 / 2.0
A KuBank 3.0 cabinet stores 836 kWh in the IEC version and 940 kWh in the UL version at 418 or 450 kW, while the smaller KuBank 2.0 is rated 277 kWh and 125 kVA. It is an energy storage system with built-in PCS for factories, retail centers and warehouses where peak demand charges show up in the bills.

Description
The inverter is built in, so the cabinet connects straight to the low-voltage network, KuBank 3.0 IEC at 800 V and KuBank 2.0 UL at 480 V. Inside are 314 Ah LFP cells in liquid-cooled IP67 modules, and the IP54 / NEMA 3R cabinet stands outdoors over −30…+55 °C. AC round-trip efficiency is up to 90 %. Peak shaving and demand management run in the controller, so no external EMS is needed for these tasks. Ethernet, RS485 or CAN with Modbus link it to plant automation and meters. Up to 8 cabinets run in parallel for more power. The certificate set IEC 62619, IEC 62477, IEC 63056, UL 9540, UL 9540A, UL 1973 and UL 1741SB covers connection requirements in Europe and North America.
How to choose
Start with how much demand must be shaved and for how long, which gives the cabinet count. A small plant gets by with a KuBank 2.0 at 125 kVA and 277 kWh, while a factory takes KuBank 3.0 and grows to 8 cabinets. For megawatts and a medium-voltage connection, move to SolBank 3.0 containers at 5,016 kWh or a PowerBlock at 10–34.5 kV.

FAQ
How many KuBank cabinets can run in parallel?
Up to 8 cabinets. With KuBank 3.0 at 836 kWh each in the IEC version, that is sizeable capacity without moving to containers.
What is the difference between KuBank 3.0 IEC and UL versions?
The IEC version gives 836 kWh and 418 kW at 800 V, the UL version 940 kWh and 450 kW.
Which communication protocols does KuBank support?
Ethernet, RS485 and CAN with Modbus data exchange, enough to link it to SCADA and meters.
Can a KuBank cabinet be installed outdoors?
Yes, the IP54 / NEMA 3R enclosure and −30…+55 °C range are meant for an outdoor pad.
