Savings depend on your usage, tariff and system. Blackout protection requires compatible equipment and a designed backup installation.
Will the system suit your needs? Will it be installed properly, set up correctly and supported years later? Sunterra takes care of the whole journey — from understanding your energy use and designing the system to installation, optimisation and ongoing support.
Start with your bills, daily habits and priorities — lower bills, greater independence or backup — so the proposed size has a clear basis.
Consider compatibility, installation space and backup needs. Make the scope and exclusions clear.
Plan the cable route and equipment location, coordinate installation and required compliance, then connect and commission the system.
Set charging schedules, operating modes and any backup reserve around your tariff and priorities. Explain your monitoring and controls.
Keep Sunterra as your point of contact for troubleshooting, system support and warranty enquiries long after installation.

Start with your energy use and everyday habits.
Three simple steps. Everyday questions. An indicative solar and battery plan to explore.
Loading your energy assessment… You can also ask Sunterra about your home.
Tell us about your home and how to reach you. Our team can help you explore a suitable solar and battery option.
Using less grid power is one thing. Never needing it is another. Long cloudy spells may mean more panels, a bigger battery or a backup generator. Sunterra designs a system to suit your home, needs and budget.
Charging at expensive times or selling solar for very little can mean lower savings. Sunterra sets up your system for you and can help adjust it remotely when your needs change.
Use spare solar during the day, or a cheaper grid rate if your plan offers one. This can leave more battery power for the evening. Sunterra gives you practical tips to save more, based on how your home uses power.
No. Battery rebates are still available.
The rebate rules have changed, with less support for each extra kWh above 14kWh. That makes choosing the right size even more important.
A battery that suits your home can still help lower your bills, with rebates helping reduce the upfront cost. Sunterra helps you choose the size you need and explains what you would pay after eligible rebates.
It depends on your daily consumption, when you use power, surplus solar and backup needs. A recent electricity bill is a useful starting point; interval usage data gives a clearer picture.
It may be possible. The right approach depends on your current inverter, electrical installation and proposed equipment. Sunterra can discuss these checks with you.
Only if the system is designed and installed for backup. Ask which circuits can operate, what power limits apply and whether backup equipment costs extra.
Savings depend on your usage, tariff, solar generation, battery operation and any VPP arrangement. Request estimates with the assumptions clearly stated rather than relying on a universal savings figure.
We deliver turnkey energy solutions for homes, commercial and industrial sites, and large-scale ground-mounted solar projects. Our services cover design, installation, commissioning, grid connection, and ongoing operation and maintenance.
For your home, that means bringing solar and battery storage together with a team experienced in delivering complete systems.
