Modular mobile solar power

Power. Beyond the grid.

Three modules. One adaptable energy system.

One platform

Build exactly the power you need.

One transport envelope. Three functions. Start with M1, then add storage or generation.

M1 All-in-One

30kW

Hybrid inverter · 3-phase

System core: inverter, EMS, 60 kWh LFP battery and 20 kVA diesel backup.

M2 Battery

150kWh

Nominal LFP storage

Adds storage with its own MPPT solar charging. Uses the inverter in M1.

M3 Solar

14.96kWp

34 PV modules

10 panels on the enclosure plus 24 deployable ground cassettes.

Modules connect through bOFFx LINK: proposed DC connection, communication and mechanical corner coupling. Final interface and protection arrangement are defined in detailed engineering. Illustrations are schematic.

M1 · All-in-One

A self-contained energy hub for remote sites, temporary facilities and backup power. Compact outside. Complete inside.

EMS coordinates solar, storage and generator. *90 % usable state-of-charge window. Generator ≈ 16 kW at cos φ 0.8; higher loads are shared with the battery. Render shows the folding enclosure, not the final internal layout.

M2 · Battery

150kWh

Keep energy available — day and night. Without a second inverter.

Own PV via dedicated MPPT

Integrated storage management. Battery racks, BMS and thermal management inside the same transport envelope. Approximate module mass 3.0 t.

Connected through LINK. M2 supplies the shared system through M1. Battery voltage and BMS compatibility with M1 are confirmed in detailed design.

M3 · Solar

More sun. More daily energy.

One transport module unfolds into a full solar field.

Plan view, to scale. Cassettes are stored vertically on rails and deploy on folding ground supports. At ≈ 45° tilt each row stands ≈ 1.2 m high; a ≈ 4.3 m pitch keeps rows unshaded at solar noon in December at 45° N. Final geometry requires engineering confirmation.

*Average continuous load solar alone could cover over a year, before conversion losses. Expect roughly one third of the annual average in mid-winter and up to about 1.5× in mid-summer at 45° N. Additional M1 units may support higher output, subject to inverter compatibility.

Yield = installed kWp × 3.5 kWh/kWp/day, consistent with ≈ 1,280 kWh/kWp/year for optimally tilted, unshaded arrays in continental south-east Europe. Panels left vertical on the enclosure produce considerably less. Not a site-specific forecast.
