P4-CORE / PV-ESS-DIESEL HYBRID

You have a power problem.
This solves it.

One cabinet replaces your grid tie, diesel control, solar input and backup UPS. Battery, hybrid inverter, switching and PV interface, all in one. Drop it on site, tap start, done.

THE REALITY ON SITE

If power decides whether you make money that day, you already know the problem.

Grid that drops without warning. Diesel that burns cash around the clock. Expansion blocked because there's no more power to give. Critical loads one outage away from a very expensive day. Pick the ones that sound like your site.

Diesel is bleeding you

Generators running 24/7 to hold standby, burning fuel that has to be trucked in. The fuel bill is the biggest line item and it never stops.

The grid can't be trusted

Outages hit without warning. Every drop risks drives, processes and batches. Recovery takes hours. The cost lands after the lights come back.

Growth is blocked

The site needs more power to expand, but the grid upgrade is years away or simply not coming. Production is capped by the meter.

Critical loads are exposed

Pumps, comms, control systems, all your critical loads. The things that cannot stop are also susceptible to damage from poor quality power, shortening their life.

THE SOLUTION

One cabinet. Four jobs done.

P4-CORE takes the four systems you'd normally buy, install and service separately, and puts them in a single air-cooled cabinet. Solar in. Battery storage. Grid tie. Diesel control. All managed by one controller.

It runs grid-connected, hybrid, or fully off-grid. Battery holds your standby load so diesel only runs when it has to. When the grid drops, it switches in under 10 milliseconds. Your critical loads never notice.

WHY THE CORE WINS

The numbers that change how your site runs.

Not features for the brochure. The things that show up in your fuel bill, your uptime, and your maintenance schedule.

10ms
SEAMLESS SWITCH

Critical loads never blink

Grid to off-grid in under 10 milliseconds. No external transfer switch. Drives, pumps and process control ride straight through any outage, on clean, stable power that extends equipment life rather than eroding it.

100%
OFF-GRID CAPABLE

Runs as its own microgrid

No external PCS or controller needed. Black-start capable, frequency-forming. Drop it on a remote site with solar and diesel and it just runs.

10min
RAPID MAINTENANCE

Service in minutes, not days

Quick-connect plugs, independent distribution box, one-tap external start/stop. Designed so a site team can service it fast, with minimal training.

AIR-FIN COOLING

Nothing that wears out

Patented air-fin self-cooling. Fanless, so it runs quieter and there are no moving cooling parts to fail. Lifetime maintenance-free cooling.

10k+
CYCLE LIFE

Built to outlast the site

CATL LFP cells, 10,000+ cycles. Daily deep cycling for many years of service. Quadruple protection from cell to system, with full fire suppression.

FOOTPRINT

250 kWh in a parking space

250 kWh in just 2.23 square metres. IP67 sealed battery, IP55 system. Back-to-back layout. Expandable to 12 cabinets and 3 MWh as you grow.

SIZE IT IN 30 SECONDS

How many do you need?

Three numbers from your site and we'll show you what it takes to cover your critical loads now, and what it takes to future-proof the whole operation.

Don't have the exact numbers? Ballpark will do, or fill them in later.

Enter your peak and critical load to see your indicative configuration.
Essential, covers critical now
0cabinet(s)
Protects your critical load and rides through outages. The minimum to solve the immediate problem.
Recommended, covers full peak
0cabinet(s)
Carries your full peak load with comfortable backup. The configuration most sites land on.
Future-ready, peak + growth + backup
0cabinet(s)
Headroom for expansion and longer backup. Size once, grow into it, never rip and replace.
WHERE IT FITS

One platform, three ways to run it.

Mixed-grid

Grid plus solar plus diesel plus storage, balanced automatically. Cut diesel hours, shave peaks, ride through outages, all on one controller.

Off-grid

No grid at all. Solar charges by day, battery carries the night, diesel only fills the gaps. A complete standalone microgrid in one cabinet.

Emergency backup

Grid-tied, sitting ready. The instant power drops it takes over in under 10 ms. UPS-grade protection for the loads that cannot stop.
