Battery sizing should match your actual household usage, not a generic package. A good installer will look at your daily and evening power draw, your existing (or planned) solar array, and your local network company's rules before recommending a unit size. Always check whether the installer's electricians are registered with the Electrical Workers Registration Board (EWRB) and, where relevant, hold SEANZ membership - both are checkable for free on the public registers.
Not every battery installation is configured to keep your power on during an outage, so ask specifically about backup-power capability before you sign anything. Also compare warranty terms carefully: battery warranties are typically separate from inverter and installation warranties, and the length and cycle-count terms vary significantly between Tesla Powerwall, Fronius, Alpha ESS and other brands.
Adding battery storage to an existing or new solar system typically costs an extra $8,000 to $15,000 in New Zealand, depending on battery brand, capacity and whether it's a retrofit or installed alongside new solar panels. Get a fixed quote from a local installer for your specific usage.
No - batteries can be charged from the grid on off-peak rates as well as from solar, though pairing a battery with solar panels generally gives the best return by storing your own generated power for evening use rather than exporting it cheaply.
Only if it's specifically configured for backup power. Some grid-tied battery installations are set up purely for cost savings and will not power your home during a grid outage unless an automatic transfer switch or backup circuit has been installed - always confirm this with your installer.
Warranty terms vary by brand and are usually separate from the installer's workmanship warranty. Tesla Powerwall, for example, carries its own manufacturer warranty, while installers add their own guarantee on the installation itself - ask for both in writing.
It depends on your power usage patterns, existing solar setup, and how much you value outage backup. A local installer can run the numbers on payback period based on your actual power bills before you commit.
