If you need serious AC power on the road, an Indianapolis company may interest you. Real Power manufactures integrated mobile AC power-generation systems — driven off a PTO — that can take AC power to remote work sites to operate construction equipment, for example, or to provide emergency power. Unlike traditional auxiliary gen sets that require fuel to be brought to them, the trucks can be driven to the nearest fuel station or can be refueled on-site.
Real Power offers a range of mobile power solutions from 12kW to 180kVA, available in voltages from 120 to 480 VAC, in single- and three-phase power. There are many offerings ranging from a multitude of generator sizes to accommodate a variety of needs, all to customer-defined interface solutions. They can do work previously requiring expensive, noisy space-consuming gen sets.

To put this in perspective, a heavy-duty pick-up truck running one of the company’s smallest systems becomes a mobile power station capable of generating a clean, continuous 8,000- or 12,000-watt stream of power — enough to power an average home while operating multiple appliances.

The other option is usually an inverter-based power system that can potentially cause serious damage to your truck, Real Power claims, and most vehicle manufacturers look unfavourably on installing a 400-volt power source directly into the truck’s electrical system. A Real Power generator doesn’t alter the truck’s electrical system at all.

The "lightweight, low-maintenance, low-profile, weather-resistant" generator typically mounts between the vehicle’s frame rails. There’s no lost ground clearance, and no modification to the chassis is usually required. Real Power is a true AC generator, and there’s no need for batteries, engine-driven belts, DC capacitors, inverters, converters, or similar electronic components. When it’s turned on, the truck becomes a pure AC generator; when it’s turned off, it’s completely disengaged, meaning no loss of horsepower or fuel efficiency.
