Solar Batteries Perth & WA: Home Battery Installation

We install home batteries from FoxESS, Alpha ESS, Growatt, GoodWe, Sigenergy (SigenStor) and SAJ. The models we use are selected from the Clean Energy Council approved lists, and your written quote names the exact brand and model.

Often, yes. We check your existing inverter, panels and switchboard first. Depending on what you have, we either add an AC-coupled battery alongside your current inverter, or replace the inverter with a hybrid inverter that connects the battery on the DC side. Any inverter or switchboard upgrade is listed separately on your quote.

A DC-coupled battery connects to a hybrid inverter that also runs your solar panels, so solar can charge the battery directly. An AC-coupled battery has its own inverter and connects on the AC side, so it can work alongside an existing solar inverter. Which suits you depends on your current inverter, its age and warranty, and the network's export and inverter limits.

Usually when your current inverter isn't compatible with the battery you want, is near the end of its life or warranty, or when a hybrid inverter is the better fit for your goals and the network's rules. If a swap is needed, we explain why and list it on your quote.

Not every battery system provides backup. Many systems switch off with the grid unless they are designed and wired for backup. Where backup is included, it usually covers selected essential circuits, such as lights, the fridge and some power points, rather than the whole home. We explain exactly what would be backed up on your quote.

Essential circuits are the circuits a licensed electrician connects to the battery's backup output, such as lighting, the fridge and selected power points. High-load appliances like ducted air conditioning, ovens and pool pumps are usually left off backup, because a battery has a limit on how much power it can supply at once.

Eligible batteries can receive support under the federal Cheaper Home Batteries Program, and eligible Synergy and Horizon Power customers may also get the WA Residential Battery Scheme rebate. Total Solar is a WA Residential Battery Scheme vendor. Conditions apply, including connecting to a virtual power plant (VPP) in some cases. See our WA rebates guide.

It depends on how much power you use in the evening and overnight, whether you want backup, and your budget. Usable capacity (kWh) is how much energy you can draw on, and power (kW) is how much the battery can supply at once. We size the battery from your bills and usage.

The manufacturer provides the product and performance warranty, and terms vary by brand and model. We provide a written workmanship warranty on our installation, and your quote lists the warranty for your exact model. You also have automatic consumer guarantees under the Australian Consumer Law.

No. Never open your switchboard or take apart your inverter or battery. They can hold dangerous voltages even when switched off. If something looks wrong, follow the shutdown steps on the label or in the owner's manual and call a licensed electrician.
