Harrington Solar Batteries

When the grid goes down or peak rates kick in, a battery keeps your home running without any fuss. That is what makes solar batteries in Harrington so worthwhile. The energy your panels collect during the day stays with you instead of flowing back to the grid for next to nothing. Walker Electrical - Solar & Level 2 installs systems that make this happen, so more of the power you generate actually gets used.


The right battery comes down to how much power you need, when you use it and what your panels can already produce, so we check all of this before we put a plan together. We only fit trusted products that meet Australian Standards, and we handle the job from design through to testing so everything works as it should. It is a good fit whether you are adding storage to your current setup or planning a full solar upgrade.


The benefits add up quickly. You get reliable backup when the power cuts out, lower electricity bills and much less reliance on the grid. Give us a call on  0498 998 085 and we will help you find the right solar battery for your home.

Frequently Asked Questions

  • What size solar system do I need?

    The right system size depends on your household’s energy consumption, roof space, and long-term goals. Most homes benefit from systems between 5kW and 10kW. Analysing past electricity bills and usage patterns can help determine an optimal setup. It’s important to consider potential future energy needs, such as electric vehicles or appliances, to avoid under-sizing. A larger system may also offer better savings if your feed-in tariff supports exporting excess energy.

  • How long does it take to install a solar battery?

    Most solar battery installations are completed within a single day, though the exact time depends on the complexity of the job. A straightforward install alongside an existing solar system may take only a few hours. Jobs that involve switchboard upgrades, backup wiring or fitting panels at the same time can extend into a second day. Site conditions, cabling distances and the chosen mounting location all play a part. A qualified installer will usually assess the property beforehand and provide a clear timeframe, so the household knows what to expect before any work begins on the day.

  • Are solar batteries safe?

    Solar batteries are safe when installed correctly by a qualified professional and used as intended. Reputable lithium batteries include built in safety features such as temperature control, monitoring systems and protections against overcharging. Proper installation matters greatly, as correct placement, ventilation and wiring all reduce risk. Choosing products that meet recognised safety standards adds a further layer of assurance. Like any electrical equipment, a battery should be installed following regulations and manufacturer guidance rather than as a DIY project. When these steps are followed, solar batteries have a strong safety record and operate reliably in homes around the country.
