Solar panels are only half the story. Most of what a rooftop system makes lands in the middle of the day, when the house is empty, and the power you actually buy back is used at night. A solar battery in Adelaide closes that gap by holding the surplus until you need it, after dark or when the grid goes down.
NG Elec designs and installs battery systems for homes and businesses across Adelaide and the surrounding council areas. Our team has worked with solar and electrical systems for over 20 years, and every system we size is built around the way your property uses power rather than a package off a price list.
Most Adelaide properties come to us one of two ways. If solar is already on the roof and the inverter is healthy, an AC coupled battery bolts onto what you have. If the system is ageing or the inverter is due, replacing it with a hybrid inverter and battery in one go is usually the cleaner build.
Either path is a job we do every week. What we will not do is fit a battery to an array that cannot fill it, because storage only pays back on surplus that already exists.
| What to check | Usually a retrofit | Usually a combined install |
|---|---|---|
| Age of the existing system | Under about 8 years | Older, or inverter faults already showing |
| Inverter condition | Working and supported | Out of warranty or unsupported |
| Roof capacity | Array already covers daytime use | More panels needed to charge a battery |
| Build work | Battery and hybrid unit added alongside | Inverter replaced, whole system commissioned as one |
If panels are already on the roof, storage is where the next gain sits. A well designed battery lets you use more of what you generate, cuts the power you draw during peak tariff periods, and keeps essential circuits alive through an outage.
For businesses, the driver is usually demand and continuity: keeping refrigeration, tills or servers running, and flattening the peaks that shape a commercial bill. For households, it is night time consumption and blackout cover. Either way the answer starts with your load profile, which is why we look at your usage before we recommend a size, and why a battery pairs naturally with residential solar panel installation when the array is being upgraded at the same time.
Every system is designed around your needs, whether you are adding storage to an existing solar setup or starting from scratch.
All installations come with a lifetime workmanship warranty, and we offer discounts on scheduled maintenance.
Some properties, particularly in the Adelaide Hills and out through Yankalilla and Victor Harbor, are chasing independence rather than savings. That is a different design: bigger storage, generator integration where it is warranted, and a load strategy that assumes a run of cloudy days.
Our off grid solar system installation work covers the full build, and a grid connected battery can be specified now so the step to off grid later is an expansion rather than a rebuild.
We work with premium lithium based systems from Tesla, BYD, Sungrow and Sigenergy. They differ in useful ways: how they behave in a blackout, whether the inverter and battery come as one unit, how far you can expand later, and what the monitoring app actually shows you.
Strong whole home backup and a mature monitoring app.
Modular stacking, so capacity can grow with the household and EV charging can be brought into the same system.
Hybrid inverter and battery pairings that suit a straightforward retrofit.
Modular capacity with a long track record in Australian conditions.
Our team is Tesla Certified and holds Solar Accreditation Australia accreditation, and NG Elec is an approved seller under the New Energy Tech Consumer Code. We install what suits the property. If two brands both fit, we tell you what separates them instead of steering you at one.

Trusted by homeowners and businesses for battery solar solutions in Adelaide
Supplying premium battery brands including Tesla, BYD, Sungrow & Sigenergy
We work with real properties, real goals, and real savings in mind. Our team delivers solar battery installation in Adelaide that’s tailored, tested, and built to perform for years—no shortcuts, no guesswork.
We quote every system after seeing the property, because the variables sit outside the battery itself.
Rebate and feed in tariff settings in South Australia change, so we confirm what applies to your address at quote stage and point you to the official source rather than quoting a number that dates. The quote itself is free and itemised.
We install across Adelaide and the surrounding council areas, with an eastern and southern suburbs focus taking in Unley, Burnside, Mitcham, Marion, Holdfast Bay, West Torrens and Onkaparinga, plus the Adelaide Hills, Mount Barker, Victor Harbor and the Fleurieu. Local jobs are covered on pages such as solar electrician Unley and electrician Burnside.
Yes. Most existing arrays can take an AC coupled battery, or a hybrid inverter can replace the current one where it is ageing. We check the inverter, the array output and the switchboard first, then design storage that connects cleanly to what is already there.
That depends on usable capacity and what you leave running. Sized against your evening usage, most home batteries comfortably cover overnight demand, and in backup mode a nominated set of essential circuits will run considerably longer than the whole house would.
We install Tesla, BYD, Sungrow and Sigenergy. Each suits a different situation, so we recommend based on your backup needs, the space available and whether you want to expand the system later.
Only if it is installed with backup capability, which is a specific gateway and a set of essential circuits wired at the board. We quote backup as an explicit item so you know before you buy exactly what stays on.
Size follows your evening and overnight consumption, not the size of your array. We use meter or inverter data where it exists, then match usable capacity to the hours you want covered, allowing for an EV if one is on the way.
Price depends on capacity, whether the inverter is being replaced, and the backup and switchboard work involved. We quote in writing after a site assessment, free of charge, with rebate eligibility confirmed for your address at the time.
A battery is not a gadget bolted to the wall. It changes when you use the power you already generate, and it keeps the lights on when the street goes dark. Tell us how your household or business runs and we will size a system that matches it, then install it properly the first time.
