Solar batteries Byron Bay

Solar batteries in Byron Bay: power that stays on when the grid does not

Anyone who has lived around Byron through a big east coast low knows the drill: trees over lines, days without power, and a fridge full of food going warm. Since the 2022 floods, most battery conversations we have in this town start with resilience, not just bill savings. Tom Sexton’s local team installs battery systems across Byron Bay and the Northern Rivers that store your solar through the day and keep the essentials running when the network goes down.

Backup, explained honestly

What a battery actually keeps running

A battery does not automatically back up your whole house, and any quote that glosses over this is hiding something. During an outage the battery supplies its backup circuits: the circuits we wire through the backup side of the system when we install it. Choose them well and a blackout barely registers. Most Byron homes prioritise the fridge, some lights, the internet router, a few power points and, where the capacity supports it, water pumps for properties on tanks.

Whole home backup is possible with the larger systems, but big loads like ovens, pool pumps and air conditioning drain any battery quickly. We walk through your switchboard with you, agree exactly which circuits go on backup, and put it in the quote so there are no surprises the first time the grid drops out.

Why now

Storm season is the argument

Byron’s grid runs through trees, floodplains and salt air, and every storm season tests it. A correctly configured battery takes over in a blackout, and while the sun is up your solar keeps recharging it, so a multi day outage becomes an inconvenience instead of an emergency. The rest of the year it earns its keep the ordinary way: storing your cheap midday solar and spending it in the evening instead of buying peak rate power.

On flood prone sites we also think hard about placement, mounting batteries and inverters high, a practice we cover on our Northern Rivers page.

What we install

Three battery brands, all with backup available

We install Sigenergy, Sungrow and Fox ESS. All modular systems that start small and grow, every one with blackout backup available and a 10 year or better warranty. Every figure below comes from the manufacturer datasheets, compared properly on our battery brand page.

Sigenergy SigenStor

Stacks from 5.2kWh to 54.2kWh per tower, with battery, hybrid inverter and EV charging options in one modular unit.

Sigenergy details

Sungrow SBH

5kWh modules expandable to 40kWh per stack, from one of the most established inverter makers in the country.

Sungrow details

Fox ESS CQ6

Stackable from 12kWh to 83.9kWh with a 12 year warranty, for homes that want serious capacity.

Fox ESS details

Our process

From site check to switch over

1 Get in touch

Tell us about your solar, your bills and what you want to keep running in a blackout.

2 Compatibility check

We check your existing inverter and switchboard, and design retrofit or hybrid accordingly.

3 Backup plan

We agree your backup circuits with you and fix them in the written quote.

4 Expert install

Our team installs, configures and tests the changeover, usually in a day.

5 App and aftercare

Monitoring on your phone, and a local crew on the end of it long after the install.

What it costs

Straight talk on battery pricing

Battery quotes vary with capacity, backup scope and your existing hardware, so the honest number is a fixed quote after we have seen your switchboard. As a guide, here is our typical retrofit starting point. Call 0420 141 078 for a realistic range over the phone.

From $9,990 installed, typical 10kWh retrofit, before rebates

Indicative price for a typical 10kWh retrofit battery added to a compatible existing solar system: standard single storey install, battery adjacent to the switchboard, dedicated backup circuits extra if you want them. Government battery incentives may apply, and we confirm your eligibility in the quote rather than baking an assumed rebate into a headline price.

Good questions

Byron Bay battery questions we get every week

Which circuits should we put on backup?

Start with what a blackout actually threatens: the fridge and freezer, some lighting, the internet router and a few power points for phones. On rural Byron properties, tank water pumps are usually next. Big loads like ovens, air conditioning and pool equipment drain a battery fast, so we only include them where the capacity genuinely supports it. We agree the list with you at your switchboard before we quote.

Will the solar keep charging the battery during a long outage?

With the systems we install, yes, when the backup function is configured. The system disconnects from the failed grid, runs your backup circuits, and uses daylight to recharge the battery, which is what turns a multi day outage from an emergency into an inconvenience. It only works if it is designed and set up correctly, which is exactly the part we do not leave to chance.

Can I add a battery to the solar system I already have?

Usually. Depending on your existing inverter, we either add a compatible battery system alongside it or upgrade to a hybrid inverter as part of the job. We check your hardware model before quoting and tell you which path is cheaper over the life of the system, not just on day one. If your inverter is near the end of its life anyway, our Byron Bay inverter page covers the upgrade path.
