What should you know before installing an Off-Grid solar system?
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:
- 1-bedroom property: 10 kWh/day baseline
- 2-bedroom property: 20 kWh/day baseline
- 4-bedroom property: 30+ kWh/day for full family occupancy
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.
