Dodgy solar battery installs, channelling another pink batts disaster. What you need to know – CyberShack
Summary
Thousands of Australian homes have received solar battery installs that breach the AS/NZS 5139 standard, risking voided insurance and potential fires. The article highlights common illegal placements (inside roof cavities, too close to doors, windows, gas appliances, etc.), examples of certified but non-compliant installs, and practical rules to follow when getting a battery fitted. It also covers battery type (insist on LiFePO4), IP ratings for external installs, council zoning issues (flood/fire), VPP traps, inverter compatibility and realistic payback expectations.
Key Points
- Many installs breach AS/NZS 5139 — non-compliance can void insurance for battery fires.
- Batteries must not be inside habitable spaces, roof or ceiling cavities, or within prohibited distances to doors, windows, gas cylinders/meters and certain appliances.
- Dodgy suppliers and complicit certifying electricians can produce apparently ‘signed off’ but unsafe installs.
- Always insist the installer inspects the site before quoting and provides a fixed all-up price (Rule #1).
- For external installs insist on a suitable IP rating (preferably IP55+; IP65–67 for exposed/marine locations) and consider weather/fire-resistant enclosures.
- Specify LiFePO4 chemistry in writing — some suppliers supply cheaper Li‑ion alternatives with lower usable capacity.
- Check local council zoning (flood and fire levels) before committing to location or ground-mounts.
- Ensure inverter compatibility — cheap systems may need expensive inverter/cabling upgrades to accept a battery.
- VPP participation is not mandatory — watch paperwork and possible hidden commissions.
- Realistic payback depends on how much excess solar you actually produce and use; battery benefits vary widely by household usage.
Context and relevance
This story matters if you own, plan to buy, or are having a solar battery installed. It ties into wider problems with rushed government rebate schemes that can encourage low-quality installs and cowboy operators — reminiscent of the old ‘Pink Batts’ debacle. With federal rebates (30%) in play, more consumers are buying batteries upfront and may later discover location, product and compliance issues that are expensive or impossible to fix.
Content summary
The article summarises key prohibitions from AS/NZS 5139 (no indoor/roof cavity installs, minimum clearances from doors/windows/gas appliances, restrictions near escape routes and vehicle access, and manufacturer exclusions). It shows stock images illustrating bad and good installs and lists practical requirements like non-combustible backing where a battery sits within 300mm of a habitable room wall.
Practical reader advice is provided as simple rules: get a pre-quote site inspection; put installation and product requirements (positioning, IP rating, LiFePO4 chemistry) in writing; confirm council flood/fire zoning; insist on inverter compatibility; and beware of mandatory VPP clauses.
The article also walks through sizing and payback calculations and explains why many household setups will not fully charge a battery daily — meaning theoretical paybacks are often optimistic.
Why should I read this?
Because if you’ve got a battery or are thinking about one, this could save you thousands and stop your insurer refusing a claim. It’s a no-nonsense checklist of the traps, what to demand in writing, and how to avoid cowboy installers — plus the bits most salespeople won’t tell you until it’s too late.
Author’s take
Punchy and direct: not all installs are dodgy, but enough are to make this a serious consumer-safety issue. Read the details if you want to avoid a costly or dangerous mistake.
