Why Add a Battery to Your Solar?

Store excess daytime solar

Most solar is generated midday when households use the least power. A battery stores that surplus for use in the evening.

Reduce expensive evening grid imports

Evening peak rates are the most expensive time to draw from the grid. Use stored solar instead.

Reduce dependence on low feed-in tariffs

Feed-in rates in SA have dropped significantly. Self-consuming your solar is worth far more than exporting it.

Optional blackout backup

With the right system design, a battery can keep essential circuits — or your whole home — running during a grid outage.

Can I Add a Battery to My Existing Solar?

In most cases, yes. The majority of grid-connected solar systems in Adelaide can have a battery added. The best solution depends on the age and type of your inverter, your solar system size, whether your property is single-phase or three-phase, your switchboard capacity and whether you want backup power.

Some homes can retain their existing solar inverter and add an AC-coupled battery alongside it. Others may benefit from replacing an older inverter or increasing solar capacity at the same time. Makn Energy assesses your existing system first — we don't automatically recommend a full replacement.

Our licensed SA electricians will review your setup and recommend the most cost-effective path to battery storage for your home.

Sigenergy may be worth considering if you have any of the following

Existing SolarEdge systemExisting Enphase systemTwo-phase home

Already Have SolarEdge or Enphase?

Sigenergy can be an excellent option for homes with existing SolarEdge or Enphase solar systems. Its flexible system design allows battery storage to be integrated while making use of the existing solar installation, depending on the property's current equipment and electrical configuration.

Makn Energy can assess your existing system and design a Sigenergy battery solution around it, including options for increased battery capacity and backup power.

Have a Two-Phase Home?

Sigenergy can be a particularly useful option for two-phase properties. Its flexible system architecture gives us more options when designing battery storage around homes with two-phase electrical supplies and existing solar.

Makn Energy can assess the existing solar, inverter configuration and loads across both phases to determine the most suitable Sigenergy setup, including battery storage and backup requirements.

Final compatibility depends on the existing installation and property configuration.

Important Things to Know

Is your existing solar system big enough?

Battery capacity should be matched to your solar generation and household consumption. If your existing solar system is small or older, you may benefit from adding additional panels when installing a battery. Makn Energy can review your electricity bill and existing system before recommending battery capacity.

Adding more solar at the same time

Installing additional solar panels alongside a battery is often the most cost-effective approach. A larger solar system generates more surplus to store, improving your return on investment. We can quote a combined solar and battery upgrade if your existing system is undersized.

Blackout backup — what you need to know

Battery storage and blackout backup are not automatically the same thing. If you want your home or selected circuits to operate during a grid outage, the system needs to be specifically designed with backup capability and the appropriate electrical configuration. We offer both essential-load backup and whole-home backup options where technically suitable.

Battery rebates and finance

Eligible battery installations in South Australia may qualify for current government battery incentive programs. Eligibility and incentive amounts depend on the system, installer accreditation and current program rules — we don't quote outdated or guaranteed amounts. Interest-free and low-rate finance options are also available for eligible customers.
