100up Off-grid power systems installed across Ballarat and Victoria.
for homes, farms and businesses
100UP designs, supplies and installs complete off-grid solar energy system.
We service Ballarat and remote areas across regional Victoria and Australia. The 100up installation team specialise in off-grid renewable energy systems for rural homes, farms and businesses.
Equipment is selected for the system we're designing for you. We base recommendations on reliability, compatibility and long-term off-grid performance.

responded immediately, suggesting a ..system that could be easily upgraded... Since that time... two system upgrades, both done quickly and integrating seamlessly.

Connecting is expensive or years away. A stand-alone system gives you power from the day it’s switched on.
The batteries hold less each year, or it runs short every winter. We design the replacement around your worst week.
Sheds, pumps, a workshop or a business on the property. We size for the whole load, 3-phase included.
How we size
Solar panels, batteries, inverters and generator backup are designed together. We design the system as a stand-alone power system.
Example only. A system sized for winter gets you through most dull days without dependence on a generator. On a long grey run, the generator tops up the batteries. Drag across to compare the low point with the sun coming back.
Rule 1
Enough capacity for the household’s demands at full occupancy.
Rule 2
Solar capacity based on July, when an off-grid system works hardest.
Rule 3
Storage to carry the home through two grey days in a row.
Rule 4
A second path, so one failed part doesn't mean no power.
Before winter
Send us your system details. We’ll check them against a cold, grey week in the middle of winter.
Find out if it can cope before you need it to.
the work is excellent... thrilled to be running a household of 5 people...comfortably, even in the middle of a Ballarat winter!

Ballarat, Victoria
Sandi's older off-grid system was replaced with newer technology — easier to use, more efficient, and ready for future expansion. The upgrade focused on simplification rather than overbuild, with clear options at every decision point.
Iraak, Victoria
Iraak, VIC (30km from Mildura) off-grid install: 8kW system with 22x 370W panels, Ingeteam 6TL off-grid inverter, and 9.6kWh Pylontech lithium battery. Mildura's high solar yield makes a small system viable for full-time off-grid living yea...

How it Works
Your system needs to match the people, appliances and equipment it will power. We assess those needs alongside your site conditions, winter solar production and plans for future use.

It depends. Installing an off-grid system during construction can make it easier to design the home around the power system instead of retrofitting it later. That usually means cleaner cabling, better equipment locations, and efficiencies for installation costs.
For off-grid homes, it also means designing in clear upgrade paths from day one. You’ll want to consider running extra conduit, allow space for additional batteries and inverters, and size the electrical room for future expansion. Even if you don’t install the full system on day one, having the infrastructure in place makes future upgrades much simpler and more economical.
On the flip side, the home’s final energy use isn’t always known, so installing too early can make system sizing more challenging. Pre-construction off-grid systems need an experienced designer who understands the property’s solar resource, likely future loads, and how the system can expand over time. Not every battery and inverter platform scales easily, so planning the upgrade path from the beginning can avoid expensive changes later.
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.
That depends on your power use, system capacity and how much backup you’re comfortable using.
Try the system estimate you will get a system recommendation. From there you can compare options with different levels of generator reliance. We review those choices when designing your system.
100UP uses a straightforward sizing rule: 5 kWh for the house, plus 5 kWh per person based on bedroom capacity — the 100UP Way.
That ties system size to occupancy and winter performance, not annual averages or nameplate ratings alone. Examples:
We then model worst-case winter for your location — June/July cloud, short daylight — not best-case summer production.
Winter sizing is the engineering call that decides whether the system works through a Ballarat July or merely looks good on paper.
