Brisbane-based energy company, MyNu Energy, has launched PowerQub-M, a trailer-mounted solar battery system designed to deliver off-grid electricity for farms, construction sites and regional operations.

The aim is to reduce the reliance on diesel generators as fuel shortages and rising costs impact businesses across Australia. Businesses report increasing difficulty sourcing diesel, particularly in rural Queensland and other regional areas.

MyNu Energy co-founder John Myler says demand for alternatives was growing as fuel supply challenges intensified: “We’re hearing from farmers, construction operators and regional businesses who are struggling with both the cost and availability of diesel. Power is critical to their operations, and they need solutions that are reliable, but also independent of fuel supply chains.”

The PowerQub-M combines a 3kW solar array with battery storage ranging from 60kWh to 240kWh, delivering between 25kVA and 160kVA depending on configuration. Mounted on a trailer, the system is designed for easy transport and rapid deployment in remote or temporary locations.

Unlike traditional generators, the system operates without exhaust emissions and produces minimal noise.

“Traditional generators are noisy, require constant refuelling and produce emissions that can impact workers on site. Battery-based systems provide stable, clean power without those downsides,” John says.

The system also delivers more stable power than some diesel generators, reducing wear on sensitive equipment. MyNu Energy says PowerQub-M reflects a shift towards mobile, lower-emission energy solutions, with demand expected across construction, agriculture, events and emergency response.

“We wanted to create something that could be moved easily and set up quickly wherever power is needed, whether that’s a construction site, a farm, an event or even disaster recovery situations. The trailer-based design means it can be deployed rapidly without the need for permanent infrastructure,” MyNu Energy co-founder Saun Nugent says.

“This isn’t just about sustainability, it’s about practicality. Businesses need power they can rely on, and increasingly they’re looking for solutions that aren’t tied to diesel.”
