Solar Inverter in Front of Solar Panels, With a Small Display — Walker Electrical - Solar & Level 2 In Old Bar, NSW

Old Bar Solar Batteries

Walker Electrical - Solar & Level 2 installs quality solar batteries in Old Bar to help you get real value from the energy your panels produce each day. Without storage, any power you do not use straight away flows back to the grid and earns you very little in return. A battery changes that by holding onto what your panels generate, ready for use after the sun sets or during a blackout.


Because no two households run the same way, we look closely at your energy habits, your property and the setup you already have before suggesting anything. Once we know what suits you, we manage the whole process from planning through to fitting and final testing. Everything we install is high quality and fully compliant with Australian Standards, so your choice will be a sound one whether you want storage today or a wider upgrade further down the track.


After installation, you will draw much less from the grid, cut down what you spend on electricity and always have power to fall back on when supply is interrupted. Ready to take the next step? Phone the team on 0498 998 085  to talk through your options.

Frequently Asked Questions

  • Do solar batteries work during a blackout?

    Many solar batteries can provide backup power during a blackout, but not all systems are set up this way by default. Backup capability depends on the battery model and the inverter it is paired with, as some require additional equipment to isolate the home from the grid safely. When configured for backup, the battery automatically supplies stored energy to the property when the grid goes down, often within a fraction of a second. This keeps essential appliances running through an outage. It is worth confirming backup functionality during planning, as standard grid-connected setups do not always include it.

  • What is the difference between AC and DC coupled batteries?

    AC and DC coupled batteries differ in how they connect to a solar system. A DC coupled battery stores energy directly from the panels before it is converted, which can be slightly more efficient since power is converted only once. An AC coupled battery connects after the solar inverter, using its own inverter to charge and discharge. AC coupling is often easier to retrofit to an existing system, while DC coupling is common in new installations built around storage from the start. Both work well, and the better option usually depends on the setup and whether panels already exist.

  • Can solar batteries be installed indoors or outdoors?

    Solar batteries can be installed in a range of locations, including garages, utility rooms, sheds and exterior walls. The best spot depends on the specific product, as each has its own temperature and ventilation requirements. Many batteries are rated for outdoor installation, but shielding them from direct sun and extreme heat helps preserve performance and lifespan. Indoor installations offer more stable temperatures but need adequate space and airflow. Local electrical regulations also influence placement, particularly around clearances and proximity to living areas. Choosing a cool, well ventilated and accessible location generally supports the longest and most reliable operation.
