Home battery storage that keeps the lights on and the evening bills down

Not necessarily. Panels alone cut your daytime use. A battery lets you store excess for evenings and outages, increases independence from the grid, and provides backup power during blackouts.

It depends on your goals. Enphase IQ Battery 5P (15-year warranty) pairs with Enphase microinverter systems. FranklinWH aPower (13.6kWh, generator-ready) suits homes that want strong backup. Sigenergy SigenStor suits larger homes, farms and commercial sites that want an expandable all-in-one platform.

Yes. We regularly retrofit batteries to existing systems, including systems we did not install. We will check compatibility with your inverter and switchboard first.

Yes, with the right setup. Batteries like FranklinWH aPower or Enphase IQ Battery can be configured for whole-home or partial backup, and Sigenergy's gateway switches to backup in under 10 milliseconds. We can also integrate a generator.

The SigenStor hybrid inverter, modular battery and gateway each carry a 10-year warranty. Enphase offers longer inverter warranties (25 years); Sigenergy's strength is scalability and its all-in-one design.

It depends on capacity (5kWh to 48kWh+), the brand, and how much of the house you want backed up. Enphase IQ 5P suits homes adding modest storage to an Enphase system, FranklinWH gives 13.6kWh of backup in one unit, and Sigenergy scales in 8kWh blocks. We quote the battery with the rest of your system so you see the payback on the whole thing, not a headline unit price.

It depends what is on. A typical evening load of lights, fridge, TV and cooking draws around 1 to 2kW, so 10kWh covers roughly 5 to 10 hours. Limit backup to essential circuits and it stretches much further; add a generator and it runs indefinitely. We model this from your usage when we size the system.

A garage wall or a shaded exterior wall with clearance and ventilation, close to the switchboard to keep cabling short. FranklinWH aPower and Enphase IQ batteries are rated for outdoor installation. We confirm the spot on the site visit against the manufacturer's clearances and NZ standards.

Yes. With battery storage and generator integration we configure systems for full off-grid resilience, or for grid-connected homes that want to ride through long outages. Rural and coastal properties around Auckland are where we do most of this work.

Our battery range is Enphase, FranklinWH and Sigenergy, chosen for warranty, backup performance and local support. If you are comparing against Tesla Powerwall 3, ask us and we will give you an honest like-for-like comparison on capacity, backup and warranty.
