The right battery size depends on your household's actual usage, not just how many solar panels you have. A good installer will look at your power bills, work out how much energy you use overnight and during peak periods, and size the battery to match rather than upselling a bigger unit than you need. Look for installers who are EWRB-registered for Mains Parallel Generation work and, ideally, SEANZ members, since both signal they meet the technical and safety standards required for connecting battery systems to the grid.
Not every battery installation supports backup power during an outage by default. Some setups only store solar energy for later use during normal grid operation, while others include an automatic transfer switch that keeps essential circuits running when the power goes out. Ask any installer to explain exactly what happens to your home during a blackout, and check the manufacturer's warranty terms on the battery itself, typically 10 years or a set number of charge cycles, separately from the workmanship warranty on the installation.
A residential battery system in New Zealand typically costs between $10,000 and $20,000 installed, depending on capacity and whether it's paired with new solar panels or retrofitted to an existing system. Get quotes from at least two or three local installers, as pricing varies by battery brand and household energy needs.
No. Batteries can be installed on their own and charged from the grid during off-peak, cheaper electricity periods, then used during peak times. However, pairing a battery with solar panels generally offers the best return, since it lets you store your own generated power instead of exporting it to the grid at a lower rate.
Only if the system is specifically configured for backup power. Standard grid-tied battery installations often shut down automatically during a power cut for safety reasons, unless the installer has fitted a backup or islanding function. Confirm this with your installer before assuming your battery will keep the lights on.
Most residential batteries carry a manufacturer warranty of around 10 years, or a set number of charge cycles, whichever comes first. This is separate from the installer's workmanship warranty, which typically covers the wiring and setup for a shorter period. Ask for both in writing before you commit.
It depends on your household's electricity usage patterns and existing solar setup. Homes with solar panels and high daytime generation but evening usage tend to see the strongest case for a battery, since it lets you use your own stored power instead of buying it back from the grid at night. A reputable local installer can run the numbers on your actual usage before you decide.
