Power4 UPS-BESS / Mining Operations

Keep the mine running when the power doesn't.

A battery and UPS-grade system that keeps your operation running through the power events that stop production and damage equipment. It sits on the critical-load bus, bridges the transition between power sources, and holds the mills, pumps and fans through the disturbance. Shown here at 1.5 MW. The same architecture is engineered to any size your site needs.

The real cost of a power event

Most operators know a power event stops production. Fewer count what else it takes with it.

On a mine or processing plant, a voltage dip lasting a fraction of a second can trip every variable speed drive on site. Mills, crushers, pumps and fans drop out together, and what looked like a blip on the bus becomes hours of controlled restart. The production is the visible cost. The rest arrives later.

Lost production hours

Every event, every restart

A loaded plant does not restart at the flick of a switch. Circuits are checked, drives reset, the plant brought back in sequence. The hours lost never come back.

Equipment life and damage

The cost that compounds

Drives, motors and mechanical plant take the hit every time supply dips or drops. Each event shortens useable life and pulls maintenance forward that was never in the plan.

Dewatering and ventilation risk

The clock starts at loss of power

When dewatering pumps and ventilation fans stop, the site is on a timer. Water levels and air quality do not wait for a restart procedure to finish. The exposure that makes the case on its own.

Spinning reserve, every day

Paid whether the event comes or not

Gensets held online as reserve burn fuel and engine hours around the clock, usually at low load where engines run worst. Insurance paid daily, for events a battery holds instantly.

How it changes the picture

A clean bridge between power sources.

The Power4 UPS-BESS sits on the critical-load bus and takes over instantly when supply drops. It carries the load through the transient, smooths the bus so drives never see the disturbance, and holds while generators sync and come online cleanly.

It is the control centre for your site's power, not just a battery. The difference between a momentary blip and hours of restart with damaged equipment behind it.

On a grid-connected site it rides through the dips and outages the network sends you. On an off-grid site it bridges the transitions generators cannot cover fast enough on their own. Either way, it works every time, in the background.

The economics, in plain terms

What it prevents costs far more than what it costs.

Every operation carries these three costs in some mix. The numbers are different on every site, and we would rather work through yours than quote someone else's. The pattern is consistent: a small number of prevented events can outweigh the investment.

Hours

Lost per event, restart after restart

The frequent cost

Routine trips and restarts after power events. Each one looks small. Across a year they add up to real production.

Plant life

Drives, motors, mechanical wear

The expensive cost

Power events age equipment faster than the maintenance plan assumes. The damage lands later, as early failures and rebuilds.

Every day

Spinning reserve, running always

The standing cost

Reserve gensets burn fuel and engine hours around the clock to cover events a battery holds instantly. This cost stops the day the system is on the bus.

On most operations the numbers land in favour of the system, quickly.

What the system is worth on your site comes down to the load profile, how often events occur, and what they put at risk. That is the conversation worth having. Tell us about the operation and a local representative will work through the numbers that matter for yours.

What you are getting

Built for industrial-critical loads, not the spreadsheet.

Shown here in the current 1.5 MW configuration. The same architecture is engineered up or down to any capacity, from a single critical circuit to whole-site cover.

1.5MW

Rated AC power

Carries the full critical load

Sized to take over mills, crushers, pumps, fans and controls without the load seeing the disturbance. Bigger loads get a bigger build.

1.51MWh

Usable energy at DC

Hours of headroom

Comfortable bridge for a diesel black start that does not catch first attempt, with capacity to spare on the common cases.

<20ms

On-grid / off-grid switch

Faster than the load reacts

Well inside the ride-through tolerance of VSD-driven mills, pumps and fans. The transient never propagates.

CATL

LFP cells, 285 Ah

The global leader in cells

Lithium iron phosphate: high thermal stability, no oxygen release under overcharge, long cycle life. Fully certified to UL and IEC standards.

IP56

Outdoor rated

No building required

Liquid-cooled outdoor cabinets and a containerised PCS skid. Deploys on a prepared pad. No external structure needed.

Single-point operation

Three-level BMS, full EMS

Cell, rack and master BMS with integrated fire safety, thermal management and a local monitoring and control layer.

Where it earns its place

Four events your site sees, handled the same way.

The job of the system is not to ride out long outages on its own. It is to bridge the transition between power sources without the load ever knowing.

Grid dip or outage

The most common event on a grid-connected site. The system carries the load through the dip, or holds it while on-site generation takes over. The plant never knows it happened.

Genset trip or changeover

The system carries the full critical load while the remaining units absorb load, or the backup black-starts and syncs. Comfortable margin behind it if the diesel does not catch first attempt.

Voltage and frequency transients

During normal operation the PCS smooths the bus continuously. Drives never see the disturbance. This is constant background protection, not a one-off.

Planned maintenance and reserve duty

Generation can be cycled out for service while the system carries the site. And with instant reserve sitting on the bus, gensets stop idling as insurance.

Sizing is a design conversation for each site. A grid-connected concentrator is sized differently to an off-grid operation running on gensets. Our local representatives work through the topology, the critical-load profile and the ride-through tolerance with you before anything is quoted.

Support that stands behind it

You are never on your own with this system.

With Power4 you have factory-direct support: a direct line to the manufacturer and the pool of the leading battery intelligence in the world. That backing reaches your site whichever way suits you.

Straight to your own team

If you run a local expert team, the same factory-level support flows directly to them. Full access, same depth, no layer in between.

A network of local specialists

Support also flows to our network of local specialists and contractors who service the equipment on the ground, close to your operation.

Factory engineer to site

For any major issue, a factory engineer to site is the fallback. The people who built the system are available when it genuinely matters.

All of it backed by dedicated remote monitoring.

The system is overseen through a dedicated remote monitoring program. We see in real time how it is performing, which means most things are understood and acted on before they ever become a problem on your site.
