What We Deliver on Site

A defined DC power scope, delivered under our own supervision by technicians who specialise in DC power and battery systems and hold factory training across multiple OEM products.

DC Power and Battery Systems

The Core of What We Do

We take delivery of DC power equipment on site, set it down, install it, terminate it and verify it: rectifier plant and DC distribution at all voltages, battery strings and racking, and the interconnection between them.

VRLA and lithium battery systems are where GWT's depth was formed. They are installed, interconnected, torqued and verified at any capacity, to the vendor's documentation and the project's electrical specification, under REC 38648.

Typical scopes

  • Rectifier plant and DC distribution
  • VRLA and lithium battery systems and racking
  • Battery string interconnection, torque verification and records
  • Containerised plant: site placement, interconnection and integration
  • Planned cutovers and changeovers, procedured and witnessed
Vendor-Agnostic OEM Support

Your Engineers on the Product, Our Crew on the Installation

OEM vendors and manufacturers bringing equipment into an Australian project need a local crew that already understands DC power. We take on the DC power installation as a subcontracted body of work, under our own supervision, so the vendor executes the project with its own engineers focused on the product.

Our technicians hold factory training across multiple products from multiple OEMs. That breadth is what makes us useful to any vendor: a crew that knows the product class, works to the vendor's procedures and documentation, and delivers its defined scope within the vendor's test program.

What the vendor keeps

  • Control of the product and its documentation
  • Its own engineers on the technical lead
  • Its own test program, with our scope defined inside it
  • A single DC power crew from the offsite location to the project site

Electrical and Principal Contractors

The DC Power Scope Inside Your Package

Tier-one electrical contractors

You hold the electrical package and the DC power scope sits inside it. We take that scope as a subcontracted body of work: delivered to your program and documentation, under our own supervision and licence, by our own employees who do it every day.

Principal contractors

Where DC power is let as its own package, we deliver it as a licensed contractor with our sister company's depth behind it: an offsite test location through GWT Critical Infrastructure under its own contract where the project calls for it, and installation and verification on site by us under ours.

Smaller-Scale Project Delivery

Free-Issue Equipment and Supply-and-Install

Not every DC power scope is a data centre. We deliver smaller-scale projects across commercial construction: supply and install where the project calls for it, and installation of free-issue equipment supplied by the tier-one electrical contractor or the end user.

Same technicians, same documentation, same verification, at a scale that suits the project.

Free-issue handling

  • Take-on inspection and damage reporting at delivery
  • Storage and positioning on site
  • Installation to the manufacturer's documentation
  • Verification records at handover
UPS and AC Power

Where UPS and AC Systems Sit

UPS systems are installed and verified under the vendor's lead, most often as part of the vendor's own project. We are familiar with the AC power systems every DC scope connects into, and our technicians work comfortably at the interface between the two. DC power and battery systems remain the specialism.

Working to a certified standard. Every scope is delivered under the GWT integrated HSEQ management system, mirroring the ISO 9001, ISO 14001 and ISO 45001 certified system operated by GWT Critical Infrastructure. Documentation is available on request.
