Alongside these three ranges, Dynamis builds the T-1000 series specialised for telecom sites in tropical and hostile environments, mobile generating sets, and lighting towers for construction and mining. Every set can be monitored remotely through Dynamis Webnet, with real-time alerts and a 24/7 call centre behind it.

Beyond the generating set

The rest of the power chain

A generator on its own is not a power solution. What sits between it and the load decides whether the site actually stays up.

Control and synchronising

Generator control panels and modules, automatic mains failure, and synchronising switchgear for multi-set installations that have to share load cleanly.

Conversion

Rectifiers, converters and inverters for energy applications, plus AC and DC smart solutions where the load profile justifies them.

Storage

Lithium batteries at 48 volts and VRLA batteries at 2, 12 and 24 volts for energy projects, sized on measured outage patterns rather than on a rule of thumb.

Distribution and EV

Electrical distribution systems and EV charging solutions, designed together with the supply so the charging load does not become the next problem.

DC cooling

48V DC cooling solutions for energy systems, which removes the air conditioner as a single point of failure and cuts the parasitic load with it.

Smart controllers

Smart controllers and sensors for fuel level, temperature and alarms, feeding the same dashboards your operations team already uses.

Hydrogen

Hydrogen solutions for clients whose decarbonisation targets go further than what a diesel set and a battery can deliver.

Spares

Generator spare parts and consumables held against your fleet, because a service contract without parts is a promise, not a plan.
After the sale

We run our own repair centres

Most power contracts fail on the service side, not on the equipment. Ours are backed by Dynamis repair centres for generator control panels, a spare parts stock held against your fleet, a 24/7 call centre, and engineers who commissioned the installation in the first place.

Maintenance contracts

Preventive and corrective maintenance on generating sets, with intervals set by running hours rather than by the calendar.

Control panel repair

Dedicated repair centres for genset control panels and modules, which is usually the part that fails and the part nobody stocks.

Commissioning and testing

Installation and commissioning with load bank testing on handover, so the set is proven at full load before you rely on it.

Dashboard integration

Integration with your energy operations and maintenance dashboards, so power sits alongside the rest of your estate rather than beside it.

Questions we are always asked

Power supply, in plain terms

How do you size a generating set?
From the real load, not from the sum of the nameplates. Starting currents, motor loads, the acceptable voltage dip and any future extension all weigh in. Oversizing is as damaging as undersizing: a set running at very low load wet-stacks and shortens its own life.
One large set or several smaller ones in parallel?
Parallel sets buy you redundancy and let each machine run in its efficient band as the load varies. They cost more in switchgear and control. Above a few hundred kilovolt-amperes, and wherever downtime is expensive, synchronised sets usually win.
Do you install as well as supply?
Yes. Installation, commissioning and load bank testing at handover are part of the scope. A set that has never been proven at full load is an assumption, not a backup.
Can you maintain equipment you did not supply?
We do it regularly. It starts with an audit of the installation and the control panel, because the maintenance plan has to reflect the machine that is actually there.
Lithium or VRLA?
Lithium costs more upfront and gives you cycle life, depth of discharge and a much smaller footprint. VRLA remains reasonable for standby duty with few cycles. The deciding factor is how often the battery actually cycles, which is why we ask for outage history first.
Can the diesel be reduced or removed?
Often, yes. Hybrid architectures combining solar, storage and generation cut running hours sharply, and hydrogen is an option where the target goes further. All of it depends on the load curve, which is the first thing we model.
Next step

Send us the load list and the outage history

Connected loads with their starting characteristics, twelve months of outage records, and the site constraints on space, noise and fuel. That is enough to size the installation and price it.
