The amount of the federal battery subsidy depends on the usable capacity of the battery. As a guideline, it’s usually around 30% off the total installed cost. For example, a 13 kWh battery might qualify for roughly a $4,300 discount after rebate.
Battery lifespan varies by brand and usage, but most quality battery storage units come with a 10-year performance warranty. With normal use and maintenance, you can often expect 12–15 years of useful life.
Yes, in many cases, you can retrofit a battery to an existing solar setup. This can involve installing a new hybrid inverter or using an AC-coupled battery alongside your current system. The best option depends on your existing configuration and future energy needs.
Every home uses energy differently, but if you often have excess solar during the day and use more power in the evening, a battery can make a lot of financial sense. It allows you to store surplus solar for later use, which can reduce reliance on the grid when electricity prices are highest. In many cases, this can result in a payback period of around 4 years and a simple return on investment of around 25%.
High-quality solar panels typically come with a performance warranty of 25 years, and many installers also offer workmanship and equipment warranties (covering panels, inverters, batteries, and accessories) for 5–12 years.
It’s important to retain your installation invoice as proof of purchase — you’ll usually need this for any warranty claim, and warranty terms can vary between manufacturers.

From the 1st consultation to the completion of solar installation the OHMS guys were very professional giving me confidence that I had chosen the best company. Their workmanship was also of high standard. I highly recommend this company. Thank you for the great job.

Ollie and Mark were fantastic. Clear and precise on what was required for me to achieve what I wanted, which was a battery ready system with enough panels to charge the battery up in all conditions. Nice report and presentation and every step was explained clearly, all the way to the end. Do yourself a favour and use them to install your system.
