What This Service Actually Does

We guide you in selecting and installing the right solar battery for your 4-bedroom Sydney home, from first call through certified handover. Our process is precise:

  • Site assessment: On-site evaluation of your roof space, switchboard, and current solar system (if any).
  • System design: We analyse your typical power usage, goals (bill reduction, back-up needs), and recommend fit-for-purpose battery options (no overselling).
  • Compliance focus: Every install follows AS/NZS standards, Clean Energy Council guidelines, and NSW electrical codes for safety and insurance validity.
  • Commissioning & handover: Post-install testing, system walkthrough, and compliance certificates—no guesswork, no rush.

The outcome: a right-sized, correctly installed solar battery system built to reduce your mains power draw, offer genuine backup capacity, and last for years—all with compliance and quality at the core.

Who This Is For / Not For

  • For: Sydney homeowners, owner-occupiers, and small business owners seeking lower energy bills, energy independence, and a trusted, fully licensed installer.
  • Not for: Price-only shoppers, anyone seeking DIY or “off-the-books” advice, or those wanting cash/non-compliant/non-warrantable work. We do not deliver “pay nothing up-front” schemes or speculative advice—only practical, compliant outcomes.

Frequently Asked Questions

How much will it cost?
Final cost depends on battery size, roof or ground-mounting needs, any required switchboard upgrades, and battery brand. We don’t quote “off the cuff”—all pricing is precise, site-based, and fully transparent.
How long does installation take?
Most solar battery installs complete in a single day, once scheduled—but timing may vary with complexity or concurrent solar upgrades. We’ll advise clear timelines during your site assessment.
Do I need a switchboard upgrade?
Not always. Many older switchboards or meter boxes need upgrades to safely and legally connect battery systems. We check this on site and advise only what’s required for compliance and warranty.
Which battery brands do you install?
We install only reputable, warranty-backed battery brands approved for the Australian market. Recommendations are based on performance, service support, and fit for your system.
Will this work during a blackout?
Many solar batteries can provide backup in blackouts, but not all setups are “off-grid ready” by default. We advise on backup capability, required hardware, and what your system can/can’t do before you invest.
How do rebates / incentives work?
Some NSW or federal incentives may be available depending on your setup, property type, and eligibility. While we explain current rebate processes, we do not make eligibility or savings claims.
Are you licensed and insured?
Yes. All work is delivered by fully licensed, insured electricians and solar specialists under NSW and CEC accreditation. Check current licence here.
What happens after installation?
We conduct system walk-through, hand over compliance docs, test your battery, and remain available for queries. You receive instructions on monitoring and caring for your system, plus real support—not a call centre.
