Wellington's exposed, wind-prone geography means outages happen, and a battery paired with solar can keep essential circuits running when the grid drops. Before committing, check the installer holds current Electrical Workers Registration Board (EWRB) registration for the electrician doing the connection, and ask whether they're a SEANZ member — this signals independent adherence to industry installation and safety standards rather than a self-declared claim.
Get at least two or three quotes and ask each installer for real local project references, not just marketing photos. Confirm which battery brand they're proposing (Tesla Powerwall, Sigenergy, Alpha ESS, BYD and Enphase are all sold in Wellington), what warranty covers the battery itself versus the installation workmanship, and whether the system is sized to your actual household usage rather than oversold. A written quote should separate hardware, installation labour and any grid-connection compliance paperwork.
A residential battery installed alongside solar typically runs from around $10,000 to $25,000+ depending on capacity (roughly 5kWh to 13kWh+), brand and whether solar panels are included in the same job. Get itemised quotes from at least two installers to compare hardware, installation and compliance costs separately.
No, a battery can be installed on its own and charged from the grid off-peak, but pairing it with solar panels gives the best return by storing your own excess daytime generation instead of exporting it at low buy-back rates.
Only if it's installed with backup or islanding capability, which not every setup includes by default. Ask your installer specifically whether the system will keep your essential circuits running during a grid outage, and which circuits are covered.
Most major brands (Tesla Powerwall, Sigenergy, Alpha ESS, BYD, Enphase) carry manufacturer warranties of around 10 years or a set number of charge cycles, separate from the installer's own workmanship warranty. Confirm both in writing before signing.
It depends on your power usage pattern, existing solar generation and how much you value outage backup. Wellington's exposure to storm-related outages adds resilience value beyond pure bill savings, but an EWRB-registered installer should size any system to your actual household consumption rather than a generic package.
