Battery Storage & Installation Newcastle

Battery Storage & Installation

Store your solar energy and use it when you need it most. We install and retrofit home and commercial battery systems — Tesla Powerwall, Sigenergy, GoodWe and more — so you stay powered through peak rates and outages.

Battery storage is one of the fastest-growing parts of our business, and for good reason. Newcastle feed-in tariffs have dropped to 2-5 cents while peak import rates hit 40-55 cents — storing what your solar generates and using it at night or during outages makes strong financial sense.

We install the full range: Tesla Powerwall, Sigenergy, GoodWe Lynx, BYD and Enphase IQ Battery. We're also one of the few Newcastle teams doing retrofit battery installations on older inverters — if you installed solar 5-7 years ago without a battery, we can usually retrofit one without touching your panels.

Every job is backed by our workmanship warranty and the manufacturer's product warranty on the battery system.

Common questions

How much does a home battery cost in Newcastle?

A 10 kWh battery system (supply, install, commissioning) typically runs $9,000-$14,000 depending on the brand and whether your switchboard needs an upgrade. Tesla Powerwall 3 is at the top of the range; GoodWe Lynx and BYD offer strong value mid-range. We'll model payback time for your specific bill before quoting.

Can I add a battery to my existing solar system?

In most cases yes. We check your existing inverter's battery-ready status, switchboard capacity and roof structure, then recommend the best retrofit path. AC-coupled batteries like Tesla Powerwall work with almost any inverter brand. Call us with your inverter model and we can give you a quick yes/no.

Will a battery keep my power on during a blackout?

Yes, if it's configured for backup mode. Not all batteries default to this — we set up your system with backup circuits so critical loads (fridge, lights, phone charging, select power points) keep running through a grid outage. Whole-home backup is possible with larger capacity systems.
