On site

Real projects, real commissioning

From desert oilfields to island resorts — these are working installations photographed on site, not renders.

Off-grid PV and diesel at a desert oilfield — the pumps run on daylight, the diesel runs only when it must.

Enclosures on site at a C&I project, cabled and commissioned before handover.

Our own assembly and R&D campus — where every cabinet is built and tested.

Multi-unit parallel and grid-tie testing in the lab, before anything ships.

The production line: enclosure assembly and wiring, stage by stage.

Cabinet-side commissioning and protection checks.

Delivery capability

Why projects land on time

A microgrid is only as good as the engineering behind it. Four things we do on every project, at every scale.

System architecture

PV, diesel, wind and storage on one AC bus, or an AC/DC hybrid topology — designed around your load curve, not a catalogue.

Grid-forming PCS

Virtual synchronous generator control delivers voltage and frequency support that lets weak grids accept more solar than they otherwise could.

Factory integration

Twenty-seven years of power-electronics manufacturing, from cell matching to cabinet assembly and full-system burn-in.

Lifetime support

Remote EMS monitoring, firmware updates and local field service keep the system performing after handover.

How we deliver

From first brief to commissioning

A fixed sequence, so you always know what happens next and what we need from you.

Site survey

Load curves, grid parameters, irradiance and diesel logistics — we collect what a desktop study cannot.

System design

Sizing, topology, protection and the control strategy, delivered as a drawing set you can hand to your own engineer.

Build & test

Enclosure assembly, wiring and staged testing in our lab before the equipment ships.

Commissioning

On-site grid connection, load ramp and operator handover, followed by remote monitoring.

Tell us about your site and we will send a written proposal

Send us the location, load and whether you are on-grid, off-grid or on a weak grid. You will get a configuration proposal and an indicative price — usually within one working day.
