40 kW / 92.3 kWh Off-Grid Integrated Cabinet
An all-in-one islanded power system: battery, PCS, MPPT solar input, generator input and EMS in a single IP54 outdoor cabinet. No grid connection required, no export, no grid-code approval.

Why an Integrated Cabinet Beats a Container Below 100 kW
- One delivery, one lift, one commissioning visit — no separate PCS shelter
- No civil works: it stands on a levelled gravel pad
- No separate fire wall requirement at this capacity in most jurisdictions
- Relocatable: if the mine camp moves, the cabinet moves with it
Typical Applications
| Site | Load | Configuration |
|---|---|---|
| Mine camp | 30 kW continuous, 500 kWh/day | 1 cabinet + 50 kWp PV + 40 kW genset backup |
| Island microgrid | 25 kW, 300 kWh/day | 2 cabinets + 80 kWp PV |
| Remote lodge | 15 kW, 180 kWh/day | 1 cabinet + 30 kWp PV |
| Telecom cluster | 20 kW, 400 kWh/day | 1 cabinet + 40 kWp PV |
Sizing Note
For off-grid systems the battery is sized on the worst week, not the average. Send us daily kWh for the lowest-irradiance month and we will size from that. Oversizing the array and undersizing the battery is the most common and most expensive mistake in off-grid projects.

Daily kWh for the worst month, peak kW, PV irradiance data if available, and whether a generator will be retained as backup.
