Getting the size right matters more than the brand. A good Napier installer will assess your actual household usage — not just your solar panel output — before recommending a battery capacity, since an oversized system wastes money and an undersized one won't cover an evening's use. Look for SEANZ membership and EWRB-registered electricians on the installation team, as both signal the installer is working to recognised industry standards rather than cutting corners on wiring and compliance.
Not every battery installation supports backup power during an outage by default — some are grid-tied only, so ask specifically whether the system will keep your power on if the grid goes down, which matters in a region like Hawke's Bay that has experienced severe weather-related outages. Also compare warranty terms closely: most quality batteries carry a 10-year manufacturer warranty, but installation workmanship warranties vary by installer, so get that in writing before you commit.
A residential battery system in Napier typically costs between $10,000 and $20,000 fully installed, depending on capacity and whether it's paired with new solar panels. Get quotes from at least two or three local installers to compare, since pricing varies with battery brand, installation complexity and any backup-power wiring required.
No — a battery can be installed on its own and charged from the grid during off-peak, cheaper electricity periods, then used during peak-price times. That said, pairing a battery with solar panels generally delivers the best return, since it lets you store excess solar generation for use at night instead of exporting it to the grid for a low buy-back rate.
Not automatically — it depends on how the system is installed. A standard grid-tied battery may shut down along with the grid for safety reasons, while a battery installed with backup circuits or an islanding-capable inverter (like the Tesla Powerwall) can keep essential circuits running. Ask your installer specifically about backup-power capability before you buy, and clarify which circuits in your home would stay powered.
Most major battery brands carry a manufacturer warranty of around 10 years, typically guaranteeing a minimum retained capacity (often 70%) over that period. Installation workmanship is usually covered separately by the installer, so check what workmanship warranty is offered and for how long, on top of the manufacturer's product warranty.
It depends on your household's electricity usage pattern and how much you already pay for power. Batteries make the most financial sense for households with solar panels and high evening usage, or for those in areas prone to outages who value backup power. A reputable local installer should be able to model realistic payback timeframes for your specific usage before you commit.
