As demand grows for clean, high-capacity site power, Prolectric has once again raised the bar in solar technology with the launch of ProCharge – our most powerful Solar Battery Energy Storage System (BESS) to date.
Unveiling at Plantworx 2025, where we proudly headline sponsor the new Site Sustainability Showcase, ProCharge is designed to meet the energy demands of today’s most ambitious, high-load construction and infrastructure projects – while dramatically reducing reliance on diesel generators.
A Breakthrough in Off-Grid Site Power
The ProCharge BESS is a three-phase, hybrid-ready solution built for performance, flexibility and sustainability. It features:
- 120kWh battery storage
- Deployable 5,280W solar array made up of 12x 440W high-efficiency panels
- Output up to 45kVA, making it ideal for large site compounds and high-demand applications
- Seamless integration with HVO/diesel generators (commonly 100kVA) for hybrid setups
- Skid-mounted design compatible with standard UK 3-phase distribution boards
- Remote monitoring via integrated controller and GPS tracking
This robust, solar-first power solution enables construction teams to run bigger sites for longer – all without constant refuelling, diesel emissions, or disruptive noise.
Proven Results on Kier’s A417 Project
ProCharge was first deployed as a prototype on Kier’s A417 Missing Link Project, where it delivered impressive real-world savings. In just five months, the unit helped save:
- Over £32,500 in fuel costs
- More than 62,500 kg of CO₂e
- With projected annual savings topping £69,000 and CO₂e reductions of 150,000 kg per year
That trial used a smaller 8-panel setup. The production unit – now upgraded to 12 panels – is even more powerful and efficient, reinforcing Prolectric’s commitment to engineering solutions that perform under pressure.
Clean Power for a Connected Site
ProCharge isn’t just about energy – it’s about enabling a smarter, cleaner, more connected site. With enough capacity to charge electric telehandlers, small EVs, all-terrain vehicles, mini diggers and dumpers, it’s the perfect fit for construction teams investing in zero-emission plant.
Its low-noise performance makes it ideal for night work and residential settings, while its hybrid compatibility means it can bridge the gap between fossil fuels and full electrification.
And as with all Prolectric products, ProCharge is backed by powerful data insights and remote support via our Smart Remote Telematics system, helping site teams stay informed, in control, and one step ahead.
A Solar-First Approach That Delivers
At Prolectric, we don’t retrofit diesel technology. We engineer solar-first products designed from the ground up to reduce carbon, costs and complexity – helping our customers meet their Net Zero goals without compromise.
Since the launch of our first solar lighting tower, we’ve delivered:
- Over 39 million kg of CO₂ saved
- 14 million litres of diesel eliminated
- £17 million+ in customer savings
And now, with ProCharge, we’re opening a new chapter in clean, high-capacity site power.
