How we design your Off-Grid Energy system
Your Solar Array, Inverter and Battery Sized Right
Good off-grid starts with getting the system right for the property. We can design from scratch, supply and install the complete system, or assess an existing setup.
Designed for Full Occupancy
We size for the home and its realistic future occupancy, and how you plan to use power today & in the future.
Built to Work through Worse Case Winters
We oversize arrays for dark Ballarat winter weeks, capturing enough energy in short sun windows to recover batteries fast.
Battery to Get Through Low Solar Days
48-Hour Battery Autonomy. Battery storage is designed to carry the household through consecutive low-production days.
Redundancy Where Reliability Demands It
Where practical, dual inverters and distributed battery storage reduce single points of failure.
If you need a second opinion or your setup is more complex, Talk to Fred About your System.
Tell us about your home, your site, and how you live - we'll recommend the system that fits.
Growing Families Often Benefit From Energy Systems Designed to Expand Later
Family energy demand usually grows steadily as routines, occupancy, and appliance loads increase.
Sigenergy and Deye are both capable off-grid systems. The difference is how they're built and what that means long-term. 100up designs for both. We'll help you match the right system to how you actually live, and what makes sense for your budget now.
DEYE
A strong option for families with stable long-term usage expectations. System resilience and performance rely heavily on thoughtful configuration matched carefully to household behaviour.
100up's regional design experience means Deye systems perform as intended in Victorian conditions
Capable and reliable when correctly sized and configured for your site and usage
Right choice for homes with stable, predictable energy needs
SIGENERGY
Better suited to growing households expecting higher future demand, EV charging, or staged expansion. Independent battery modules improve flexibility and maintain operation during servicing events.
Modular by design. Expand capacity or add EV charging without replacing components
Each unit operates independently, so a fault never takes down the whole system
Higher equipment cost, lower lifetime complexity
Solar System
Solar Array Options
Family growth usually increases energy demand faster than most households initially expect.
Jinko Panels
High-output panels that perform best on roofs with clear, unobstructed sun exposure.
Aiko Panels
Back-contact cell design that maintains more consistent output when part of the panel is shaded by trees, antennas, or nearby structures.
Expansion Options
EV & Expansion
Future Energy Needs Start With Smarter System Planning Today
Thinking about EV charging in a few years? We can design your system now to handle it, so you're not retrofitting later.
Electric Vehicle Charging
Capacity to run your home off grid on battery or your car in emergencies
Solar Array Expansion
Back-contact cell design that maintains more consistent output when part of the panel is shaded by trees, antennas, or nearby structures.
Backup Power & Redundancy
Back-contact cell design that maintains more consistent output when part of the panel is shaded by trees, antennas, or nearby structures.
How it works
How We Design Your Extended Family, Investment or Large Regional Property
Large off-grid properties place very different demands on a system. Multiple occupants, guest accommodation, events, workshops or seasonal peaks can create substantial loads that require careful planning from the beginning.

Understand Your Situation
We consider likely occupancy over the life of the property, not just the number of people living there today.

Start with a phone call - if you have more questions about your Bedroom home
Yes. All electrical work on a 100up system is done by licensed electricians who are accredited solar installers.
They’re a small crew Fred has worked with for years and chooses for each job. Fred designs every system and stays with it from start to finish. He does the site assessment and the design, is on site during the install, and handles commissioning and handover.
You deal with one person who knows your system and is accountable for the whole job.
Every install comes with the compliance paperwork Victoria requires, including the Certificate of Electrical Safety, plus the documentation for any STC incentives.
We handle the installation records and compliance documentation that sit with us as the installer.
Where an incentive applies, we confirm the relevant requirements when preparing your proposal.
We install across regional Victoria.
Share your property’s location when you enquire so we can confirm availability and discuss any site-access requirements.
Yes. We assess your existing equipment and power needs before recommending what can be retained, expanded or replaced.
Compatibility and equipment condition affect what’s practical.
Tell us about planned additions such as extra occupants, pumps, workshops or EV charging.
We consider those loads during design and explain the expansion options for the proposed equipment.
