Why Duntech Ultimate Lithium?
Dual Lithium Battery System
LiFePO4 lithium batteries rated for 5+ years in Darwin conditions. Not the 12–18 months you get from lead-acid batteries other brands install. The difference is engineering for Territory heat cycles, not just claiming tropical compatibility.
All-Metal Vented Battery Box
Designed specifically for Northern Territory conditions. Vented construction dissipates heat. Metal housing blocks humidity ingress. Standard plastic battery boxes crack and degrade in Darwin’s UV exposure and temperature extremes.
Duntech SunChaser Solar System
Custom-engineered solar sytem, engineered to deal with Northern Territory weather. Can be tilted and angled in any direction for optimal solar gain at your property. Built to hold position through the punishing winds we get up here. Most imported frames are flimsy afterthoughts that fail in the first serious wet season event.
Diecast Aluminium Motor Construction
Single-piece motor cover. No gaps for humidity to penetrate, no seams to work loose. Handles gates up to 800 kg at 0.33 metres per second — class-leading speed without sacrificing reliability.
Blackout-Proof Operation
When the grid goes out in Darwin — and it does — your gate keeps working. Solar charging with dual lithium batteries means no manual backup needed during power outages.
Local Parts at Honest Pricing
PC boards stocked in Darwin at $180–190. Not $300–450 shipped from interstate. When something needs replacing, you pay fair local pricing and we respond when you call.
Complete Warranty Coverage
10-Year Panel Changeover + 3-Year Full System Warranty
10-Year Panel Changeover Warranty
If your Duntech solar panel fails within 10 years, we replace it. No exceptions, no fine print. The panel is the heart of your solar system — it gets the longest protection.
3-Year Parts and Labour Warranty
Complete system coverage for three years from installation. Motor, charge regulator, batteries, wiring, installation workmanship — everything. If something fails, we fix it or replace it at no cost to you.
What This Warranty Actually Means:
Most gate motor companies make you wait 2–6 weeks for interstate parts while your gate sits broken. We stock parts locally in Darwin. When you call with a warranty issue, we respond same-day — not next month.
We issue the warranty. We honor the warranty. We stock the parts. We do the service. No passing you between the manufacturer and the installer. One company, one commitment.
Installation Process - From Quote To Operation
1. Contact Us for Your Quote
Upload a couple of photos through our contact form or give us a call. We can often quote from photos on the same call if your gate and property conditions are straightforward. If we need more detail, we will schedule a site visit.
2. Site Assessment (if required)
For complex installations or properties with specific requirements, we will come to your location. We assess gate weight, opening width, structural requirements, solar panel placement, and any cyclone protection considerations.
3. Quote and Configuration Selection
We provide a detailed quote with your choice of standard or Big Battery Kit configuration. Quote includes complete system, professional installation, and full warranty coverage. You will know exactly what you are getting and what it costs.
4. Installation Scheduling
Once you accept the quote, we schedule your installation. Most residential installations complete in one day. Commercial or complex rural installations may require additional preparation work (earthmoving, structural posts, gate fabrication).
5. Professional Installation
Licensed Dunwrights technicians install your complete system. Motor mounting, battery box placement, SunChaser frame positioning for optimal solar gain, wiring, surge protection, testing. Everything installed to Territory standards.
6. Testing and Handover
We test complete system operation. We program your remotes. We show you how everything works, including auto-close timing adjustment if you want to change it later. We do not leave until you are confident with the system.
7. Ongoing Service
Your warranty coverage begins at installation. If you need anything — service, parts, questions — you call us directly. We respond directly. Local parts. Territory expertise.
Who Is This System For?
Heavy Residential Gates
Steel gates, timber gates, dual gate configurations — anything up to 800 kg. The motor handles heavy Territory-style gates that undersized imported systems struggle with.
Commercial Properties
High-traffic commercial gates that cycle multiple times daily. The dual lithium battery system and robust motor construction handle commercial duty cycles without premature failure.
Rural and Remote Properties
Solar power with blackout-proof operation. When you are 40 km from town and the grid goes out for three days, your gate keeps working. Extended battery capacity available with Big Battery Kit.
Cyclone Fence Gates
Cyclone fencing does not mean you live without automation. We have installed Duntech Ultimate systems on cyclone fence properties across Darwin. The 800 kg case study referenced on the Duntech site — that was a cyclone fence property.
Replacement for Failed Systems
If your current gate motor is in the 2–6 week warranty runaround cycle, or if you are replacing batteries every 18 months, the Duntech Ultimate Lithium ends that pattern. Different engineering produces different outcomes.
Optional Upgrades
Photocell Sensors
Automatic closing when vehicle clears the gate opening. Eliminates manual timing or auto-close delay.
Battery Backup for Mains-Powered Systems
If you are installing a mains-powered system but want blackout protection, we can add battery backup. Keeps your gate operational during power outages.
Safety Warning Lights
Flashing lights that activate when gate is in motion. Recommended for high-traffic commercial applications or gates near pedestrian areas.
Additional Remotes
System includes two remotes as standard. Additional remotes available for family members, staff, or regular visitors.
