The technology
One cell, one module, one rack.
The four RelyEZ ranges are not four different products. They stack the same building blocks in boxes of different sizes. That is what decides maintenance, spare parts and how fast a system comes back into service.
RelyEZ GridUltra storage containers, on site
- 01Prismatic LFP · 314 Ah
The cell
Lithium iron phosphate, 3.2 V. RelyEZ does not make it: it comes from Hithium, and it is the same cell across all four ranges.
- Voltage
- 3.2 V
- Capacity
- 314 Ah
- 02RelyEZ Pack 104
The module
104 cells in series inside a sealed, liquid-cooled enclosure. This is the unit that gets replaced: in a cabinet standing in a yard or inside a container, the procedure is identical.
- Energy
- 104.5 kWh
- Weight
- 650 kg
- Ingress rating
- IP 67
- 03RelyEZ Rack
The rack
Four modules and a high-voltage box, assembled and tested in the factory. The rack is the level at which capacity is added without redrawing the architecture.
- Energy
- 418 kWh
- Cells
- 416 in series

The system
Racks are lined up, then conversion, cooling, fire protection and control are added. Only here do the ranges diverge — by size and by grid connection, not by what is inside.
- Ranges

- From
- 250 kWh
- To
- 5 MWh
In the factory
Assembled, wired and tested before it ships.
What it changes
One spare parts stock for the whole fleet.
A faulty module is replaced the same way in a cabinet standing in a yard and in a 5 MWh container. Spare parts serve every site, and the team on call already knows the procedure.
Diagnosis — The control system reports the module at fault, not just the cabinet.
Replacement — Same module, same connectors, same procedure across all four ranges.
Stock — One spare module covers every site you have equipped.
Growth — Adding capacity means adding racks — not changing systems.
The same building block, four sizes of box.
What remains is choosing the box. It depends on the grid connection, the space available and what you expect from the asset.
