New solar battery energy storage could replace diesel generators
A Bristol-based company has launched its most powerful Solar Battery Energy Storage System (BESS) to date. Prolectric’s 120 kWh lithium-ion battery pack is ideal for large site compounds and high-demand applications.
Named ProCharge BESS, the system is a three-phase, hybrid-ready solution built for performance, flexibility, and sustainability.
Prolectric claims that the system 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.
Low-noise performance
ProCharge was first deployed as a prototype on Kier’s A417 Missing Link Project, where it delivered impressive real-world savings.
The company revealed that the 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.
Prolectric claims that the system’s 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.
System can charge small EVs, all-terrain vehicles, mini diggers
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, according to the company.
The system is backed by powerful data insights and remote support via the Smart Remote Telematics system, helping site teams stay informed, in control, and one step ahead.
The system also offers seamless integration with HVO/diesel generators (commonly 100kVA) for hybrid setups. It delivers an output of up to 45kVA, making it ideal for large site compounds and high-demand applications.
Its skid-mounted design is compatible with standard UK 3-phase distribution boards. The system’s remote monitoring can be done via an integrated controller and GPS tracking.
Engineered to replace diesel generators
The fully solar-integrated energy solution is engineered to replace diesel generators across large-scale construction and infrastructure projects. Built with true off-grid autonomy, ProCharge combines 120kWh of storage capacity, high-yield PV panels, and intelligent energy management into a single skid-mounted unit.
Unlike conventional battery systems, ProCharge doesn’t rely solely on grid or generator input. Its integrated solar array enables self-charging from sunlight, drastically reducing the need for refueling and allowing sites to operate with zero fuel, zero noise, and zero emissions.
Reliable, scalable, and cost-effective clean energy
The system delivers reliable, scalable, and cost-effective clean energy, even in the most demanding environments. ProCharge is also ideal for powering cabins, compounds, welfare units, and temporary electrics on large construction projects and off-grid locations.
Reports revealed that Prolectric sales pitch isn’t just about replacing one power source with another.
It is about creating a smarter, hybrid ecosystem that works in tandem with existing diesel generators, forming a hybrid setup that uses solar-charged batteries as the job site’s primary power source, supplementing them diesel only when absolutely needed.
The result is consistent, usable power off the grid while drastically reducing the daily runtime of diesel generators, reported Electrek.
