Your roof makes cheap power at lunchtime. Your family uses expensive power at dinnertime. A battery is the bridge between the two, and it is the first thing we design, not the last thing we add.
See my numbersVictorian time-of-use pricing makes daytime power cheap and evening power dear. Without storage, your solar exports for very little at noon and you buy peak power back at night. With the right battery, the same sunshine covers your evening. We size it from your actual bill, never from a package list.
Small bills, flat tariffs and heavy daytime use can make a battery a poor buy today. Around one quote in five, we recommend waiting or starting somewhere else. That costs us sales and earns us the other four, and it is the standard our reviews are built on.
For most homes on a time-of-use tariff using power in the evening, yes, and for some homes, honestly, not yet. It depends on your bill, your tariff and whether you already have solar. Our calculator shows the maths in the open and the Energy Exam confirms it on your switchboard.
It reduces the installed price of an eligible battery by thousands of dollars, and the discount steps down on 1 January. Every price we show already includes it, and we will tell you the exact figure for your system in writing.
Usually, yes. We check your inverter, your switchboard and your export settings at the Exam, and if a retrofit is not the right answer we will say so and show you what is.
Only if it is designed to. Backup circuits are a design decision, not an accessory, which is why an engineer chooses yours with you before anything is ordered.
