Delta’s Power Pole Mounted EV Charger Hits Prime Time

Delta Electronics has announced it has begun rolling out the RapidPost 50; what the firm says is Australia’s first 50kW DC EV charger that can be directly mounted onto street power poles.

What Is The RapidPost 50 System?

Premiered at All-Energy Australia 2025 in late October this year, the RapidPost 50 system is based on Delta’s DC Wallbox 50kW charger and requires a three-phase power supply of just over 100 amps; or ideally, 125A¹. This makes it suitable to be installed on many existing power poles without the need for major substation upgrades or heavy-duty cabling. Installation can be carried out in a single day.

Boasting 97% efficiency in an ultra-slim design, the RapidPost 50 is only 25 centimetres thick. The device can supply up to 50 kW of DC charge to a single car, or up to 25 kW each when two cars are charging. The RapidPost 50 also has credit card reader; so there’s no app required for kerbside charging.

Delta is offering the solution — including commissioning, service, maintenance and repair — to local council and commercial operators through a partnership with Australian firm NHP Electrical Engineering Products, which designed and assembles the RapidPost 50 locally in collaboration with the firm.

Delta has also worked with New South Wales electricity distributor Essential Energy to assess the suitability of the chargers across its network.

“The key to continued EV adoption is through convenience in accessing a charger in the local community, as well as ease of installation and maintenance,” said Delta Electronics Australia Country Manager Tom Hew. “The fast-charging capability provided by the new 50kW DC pole-mount charger makes it an ideal solution for many councils with two-hour parking restrictions. Most EV drivers can park and charge their vehicle up to 80-90 per cent within a normal parking time period.”

Deployment is now underway in pilot locations (no specifics mentioned), with further rollouts expected next year.

Other Recently Launched Delta Chargers

The 50kW DC pole-mounted EV charger follow the unveiling of two other solutions by Delta Electronics in late September.

Delta’s UFC 200 platform offers two charging points for DC fast charging up to 200 kW, and the SLIM 100 offers a maximum power output of 100 kW; also providing simultaneous charging of up to two vehicles.

Delta Does Home EV Chargers Too

As well as its more powerful charging solutions for public, commercial and municipal applications, for those interested in topping up at home Delta manufactures a residential EV charger that is available in Australia. The AC Max comes in single-phase 7 kW and three-phase 22 kW models.

You can see how the AC Max stacks up on specifications and estimated pricing against a bunch of models from other brands on the SolarQuotes home EV charger comparison table.

A Bit About Delta

Founded in Taiwan in 1971 by Bruce Cheng, Delta Electronics evolved from a switching power supply manufacturer into a producer of energy-efficiency and renewable energy solutions.

Delta has been producing solar inverters since 1999, and EV chargers for commercial applications since as early as 2011. Home chargers followed later, with the AC Max launching in late 2019. The company began producing home battery systems in 2017.

While the firm has been present in the Australian market for over two decades, after the formal merger of Delta Electronics (Australia) and Eltek Australia on April 1, 2021, the company opened a new Australia/Pacific headquarters in Sydney; in St Leonard’s Corporate Park.

SolarQuotes Founder Finn Peacock’s general view of the firm’s gear:

“Back in the day when I worked as a control engineer in a nuclear power station, we used Delta power supplies in the boiler control systems,” he says. “They certainly know how to make reliable electronics.”

In other recent news from Delta, last month the company announced it had achieved powering all its operations with 100% renewable electricity.

“That milestone wasn’t a finish line, but a signal: we’re now accelerating toward EV100%, ensuring our mobility footprint reflects the clean energy future we engineer every day,” stated the firm.
