Custom
Off-Grid Systems:
We design systems for YOU:
We integrate water, wastewater, and energy into one design.
Each system supports the others, nothing is undersized, and everything works together from day one.
We design, deliver & install the full system
Our expert team will be with you step by step - from discovery call to hand over and a walk-through of your installed system - so you have full confidence in the day-to-day use of your OFF-Grid system.
Trusted brands and quality products are an integral part of our work.
Builders and trades who cut corners by using cheaper-inferior products take a big gamble that often costs home owners deerly in the long run.
We only work with quality brands that offer manufacturer warranties.
Engaging Stag Off-Grid will offer you piece of mind with an installation guarantee. If your system does not perform as per your design brief our team will remedy the situation.
Water Infrastructure
Reliable water is essential for comfortable off-grid living. We design systems that capture, store, pump, heat and distribute water efficiently — with energy use considered from the very beginning.
Our water infrastructure solutions include rainwater harvesting and storage, stormwater management and drainage, hot water systems, pressure and pumping solutions, and filtration where required. Each system is tailored to the property, household size, and how the home is intended to be lived in - now and in the future.
From full plumbing rough-in for new builds, to on-site water connections for relocatable or existing homes, we deliver complete water infrastructure designed to integrate seamlessly with your wastewater and energy systems.
Energy Systems
Solar and battery systems form the backbone of modern off-grid living — powering everyday comforts while supporting the essential infrastructure that makes a home function reliably.
We design solar and battery systems using a complete load profile, accounting not only for household living but also for water, wastewater and hot water systems. Where appropriate, complementary energy sources such as LPG gas play an important supporting role — reducing electrical demand, taking pressure off the battery system, and improving overall efficiency.
By thoughtfully balancing energy sources, we’re often able to reduce system size, lower upfront costs, extend system lifespan, and deliver a more economical and resilient off-grid solution. Every energy system is designed in context — tailored to the home, the land, and how it’s intended to be lived in over the long term.
Wastewater & Greywater Systems
There is no single solution for on-site wastewater and greywater management. Every property, household and way of living brings different requirements — and the right system depends on how you want your home to function day to day.
We work with a range of compliant wastewater and greywater options, from conventional septic systems, to advanced treatment and reuse systems, and alternative solutions such as composting or incinerating toilets integrated with greywater management. Each approach is considered within council and regulatory frameworks, and designed to suit both your property and your long-term goals.
From complete house drainage and rough-in for new builds, to on-site connections and system installation for existing or relocatable homes, we design and deliver wastewater systems that integrate seamlessly with your water and energy infrastructure.
