Complete solar, battery and inverter systems, designed and installed by 100UP. Sized for a Ballarat July, with the goal of running without a generator in normal use.
Choose by home size
Compare system options, specifications and installed prices by bedroom count. We design for winter, with the aim of avoiding routine generator use. We estimate daily use at 5 kWh for the house plus 5 kWh per person.
Cabins, couples, granny flats and tiny homes.
The family home, designed for 4 people.
A starting point for bigger households. EV charging, pools and home based business setups are checked separately.
Prices assume limited to no generator use over a Ballarat July. They include installation, certification and GST, after eligible solar and battery STC discounts.
Complete off-grid systems
Everything your home needs to run without the electricity grid. Designed, installed and certified. Managed end to end and then supported by 100UP.
We design the whole setup around your daily energy needs and winter solar production.
Solar panels generate electricity during the day. Solar batteries store it for the night and cloudy weather. Inverters turn that energy into power your family can use.
reliable, knowledgeable and very friendly. Solved my problem very quickly.

A practical starting point for households with steady, predictable power use.
We match the solar panels, battery storage and inverter capacity to your site and loads.
A premium option for households planning integrated EV charging or more battery storage later.
We plan the expansion pathway at the design stage, including compatible equipment and capacity limits.

How we size
Four design rules guide every off-grid installation. The goal is enough power for normal off-grid living without routine generator use.
We allow for everyone the property could hold. Then we check heating, cooking, pumps and other large loads.
We size the solar array around July conditions. It needs to run your appliances and charge the batteries when daylight is limited.
We aim for two days of storage at your planned daily use. Usable battery capacity and system losses matter here.
We design a second path where practical. What keeps running after a fault depends on the failed part and the capacity still available.

Complete off-grid systems designed to avoid routine generator use start at $44,000 for a 1-bedroom home. Systems for 5-bedroom homes start at $82,200. These prices include installation, certification and GST, after eligible STC discounts.
Your final quote depends on the site, equipment and installation requirements.
Start with daily energy use. Our initial allowance is 5 kWh a day for the house, plus 5 kWh for each person. We then check your loads and size the solar and storage for winter.
Yes, or at least some backup power source. Our design goal is to avoid routine generator use. Extended grey weather, unusually high consumption or repairs make backup power useful.
We discuss those limits when designing your power supply. Learn what generator-less off-grid design means.
Yes, if your system has capacity for expansion. Extra panels depend on inverter limits. Extra batteries must be compatible.
Learn more about balancing solar and battery expansion. Tell us your plans before installation so we can leave room to grow.
Yes. We install across regional Victoria. Further away, we may still be able to help with design and kit supply.
Yes. We can assess a stand-alone power system for an already connected property.
Going fully off-grid means designing for all your electricity use. If you want to keep the connection, tell us at the start so we can discuss the right setup.
