When the vehicle is the equipment.
Here the vehicle is the equipment. The pump, the camera chain, the diagnostic device, the repeater, the light tower: that payload is the reason the vehicle exists, and the electrical system is judged on one thing only — does the payload work when it is called for?
Is this you?
- The vehicle exists to carry equipment, and the equipment is what has to work.
- A power failure is not an inconvenience — it is a missed call-out, a lost broadcast or a patient waiting.
- The generator is a problem: it is loud, it takes time to start, and its exhaust is where people are working.
- You are a body-builder, fleet operator or installer specifying power for a unit that has to be in service every day.
The payload defines the system
Start from the equipment, not the vehicle. What it draws, for how long, and what quality of power it needs — those three numbers govern the bank, the inverter and everything downstream.
What changes in a specialised build is the definition of failure. A camper that runs out of power ends a holiday early. A response vehicle, a mobile clinic or a broadcast unit that runs out of power fails at exactly the moment it was called for. So the priorities invert: capacity matters less than availability, and availability comes from redundancy.
In practice that means more than one way to charge the bank, more than one path to the critical loads, and switching that lets whoever is on duty reconfigure power without calling a technician. Victron Energy and MG Energy Systems cover storage and conversion at this level, and Carling Technologies the switching and protection that makes a system reconfigurable rather than merely wired.
Silent, clean power instead of a generator
Instrumentation, medical devices and radio and video chains are usually specified against clean, stable AC. A generator that has to be started, refuelled and heard is often simply unacceptable.
It takes time you may not have, it makes noise where people are working or recording, and it puts exhaust where people are breathing. A properly sized inverter running off a lithium bank produces power the moment it is switched on, silently, with nothing to start. The generator, if there is one, drops back to recharging the bank rather than feeding the equipment directly.
Where a unit stands for long periods, solar keeps the bank topped without idling an engine. On a roof already covered in the equipment that justifies the vehicle, high-efficiency panels from SunPower / Maxeon earn their premium, because the area is fixed and the demand is not.
What PowerSol supplies for it
- Storage and conversion: Victron Energy and MG Energy Systems, lithium with integrated management and inverters sized to the payload.
- Switching and protection: Carling Technologies, rated for continuous duty and built to be reconfigured under load.
- Charging: Sterling Power and Victron Energy alternator and DC-DC charging for a vehicle that works its DC system hard.
- Solar: SunPower / Maxeon, where the roof is already full of equipment.
- Water: Katadyn Group treatment, for deployments where drinking water is part of the problem.
Continuous duty, and service by whoever is on shift
A recreational system is used in bursts. A specialised system may run flat out for a whole shift, in the heat, and it will be maintained by the person on duty rather than the person who built it.
That argues for components rated for continuous operation rather than intermittent recreational use, for distribution and protection that can be traced and serviced quickly, and for monitoring that reports the state of the system honestly and early enough to act on.
PowerSol's role here is specification, not certification. We distribute the components and help installers, body-builders and fleet operators assemble them into a system that fits the duty. Where an application is governed by a standard, a regulator or an operating authority, that compliance path belongs to the framework and to the operator. Bring it to us at design stage and we will specify components that fit it rather than fight it.
What to get right
- Start from the payload, not the vehicle. Exactly what the equipment draws, for how long, and what quality of power it needs. That single set of numbers governs everything downstream.
- Specify for availability, not just capacity. If the unit has to work when it is called, plan more than one charge path and more than one route to the critical loads, and be explicit about what happens when any one of them fails.
- Decide honestly whether a generator is acceptable. Where noise, exhaust, start-up delay or refuelling are a problem, a lithium bank and a properly sized inverter change the operating picture, and the generator becomes a charger rather than the primary source.
- Rate the system for continuous duty in local heat. Equipment specified for intermittent recreational use will not deliver the same numbers on a long shift in a sealed compartment in a Southern African summer.
- Make it serviceable by whoever is on duty. Labelled circuits, accessible protection, clear switching and a monitor that reports state of charge plainly are what keep a unit in service between technician visits.
- Bring the compliance framework to the first conversation. If your application answers to an operating authority or a standard, component choices are far cheaper to get right on paper than to retrofit in the yard.
Next step
Get this specified properly
Tell us what the payload is, what it draws and what happens if it stops. We will help you and your body-builder or installer specify power that fits the duty. PowerSol supplies the components and the technical support; the build, the compliance path and the operating approval stay with you and your framework.
Tell us what has to run
The vessel or vehicle, the loads, and how long they must run without a charge.
We spec it with your installer
Bank, charging, protection and monitoring sized to what you actually use, from components that work together.
Your dealer supplies and fits it
PowerSol distributes through the OEMs of our marine and automotive markets, installers and dealers across Southern Africa. They quote, fit and commission.
Frequently asked questions
What counts as a specialised application?
Broadly, any vehicle or installation where the power system exists to run equipment rather than to support a trip: rescue and emergency response, utility and municipal fleets, mining and industrial support, mobile-medical units, and broadcast or communications vehicles. If the payload is the reason the vehicle exists, and its failure is more than an inconvenience, the logic on this page applies. We are still refining this market definition with PowerSol, so if your application sits at the edge of it, talk to us.
Can a battery and an inverter really replace a generator?
For many duty cycles, yes, and the reason is usually behaviour rather than energy. A lithium bank with a properly sized inverter delivers power instantly, silently, with no exhaust and nothing to refuel, which matters when people are working nearby or the equipment is sensitive. Whether it replaces the generator outright depends on your load, your run time and your chance to recharge. Where it does not, the generator normally becomes the bank's charger rather than the direct source.
Does PowerSol certify systems for regulated applications?
No. PowerSol distributes technical components and supports installers, body-builders and fleet operators in specifying them. Where an application is governed by a standard, a regulator or an operating authority, the compliance path belongs to that framework and to the operator. We will specify components that fit it, so bring the requirement to us at design stage.
Do you supply fleets as well as one-off builds?
PowerSol sells to installers, body-builders and dealers, which is the route most fleet work takes anyway. Standardising a fleet on one component set pays off in shared spares, a single training curve and predictable diagnosis, and that is a conversation worth having before the first unit is built rather than after the tenth.
