A home battery only pays off if it's sized to your actual usage and installed by someone who understands both the electrical and software side of the system. The gap between a well-configured battery and a poorly set up one shows up in your power bill.

TopChoice recommendations are editorially curated by our New Zealand team. Rather than listing every business that pays to appear, we research each local market and shortlist only the battery storage installers who consistently stand out.
We don't host our own reviews. Instead, we draw on public reputation signals from Google and other platforms, alongside the wider research that goes into each list. Every battery storage installer is assessed using a consistent framework that considers factors such as:
Every Top 5 list is reviewed periodically and can change over time as businesses grow, improve, or fall short, so the recommendations stay current and worth trusting.
Before you commit, it pays to ask a few key questions.
A battery too small won’t cover your evening use; too large wastes money on unused capacity.
Not all battery setups provide power during a grid outage — confirm this is included if you want it.
Retrofitting a battery to existing solar needs an inverter and system check first.
Batteries typically carry a 10-year performance warranty — get this in writing along with the installer’s own workmanship warranty.
A good installer manages any required notification to your lines company and retailer for you.
TopChoice takes a curated approach by limiting each city to just five recommended battery storage installers. This avoids the clutter common in open directories and makes it far easier to compare your options without endless scrolling.
Choosing a battery storage installer can be a big decision, and it's hard to know who to trust. We do the legwork, so you can shortlist quickly and reach out with confidence. Every battery storage installer on our lists is independent, local, and chosen on merit. Featured placements may be available and are clearly labelled, but they never influence the editorial rankings.
Cost depends on battery capacity, brand and whether it's paired with new or existing solar. Get an itemised quote and compare the warranty terms alongside the price.
No, though most households pair the two. A battery can also be charged from the grid on off-peak rates and used during peak-price periods, though the payback is generally stronger when paired with solar.
Only if the system is specifically configured for backup power. Ask your installer whether backup is included, since not every battery installation supports it by default.
We editorially assess local battery storage installers using a consistent framework, public customer reviews and feedback, evidence of workmanship, clarity of service and quoting, professional standards, and communication quality. We don't host our own reviews; rankings reflect real-world reputation drawn from Google and other public sources.
No. Featured placements are available and clearly labelled, but they do not influence the editorial rankings within our Top 5 battery storage installers lists.
