Three options. Only one actually works for your business.

Agency
$2,500 to $4,000 / mo
Slow. Expensive. Removed from your business.
You get a slick site, a quarterly Google Ads report, and an account manager who thinks AC-coupled and DC-coupled are the same thing. Meanwhile the homeowner with a 7-year-old Fronius inverter rings the original installer for the battery quote, gets quoted on replacing the inverter as well, and never even hears your name.
DIY tools
$100 to $250 / mo + your evenings
Cheap, but it just hands you a dashboard.
Wix, Google Ads, a Facebook page that hasn't been updated since the last STC rule change, a SolarQuotes profile. Cheap, but you tune the bids at 9pm and the existing-inverter compatibility matrix (Sungrow, Fronius, SolarEdge, Enphase) that should be your highest-converting page never gets built. The VPP-opt-in customer goes to whoever ranks for 'Amber Electric compatible battery'.
ACTUALLY DOES IT
In-House
$299 / mo flat
Cheap, and it actually does the work.
The AI marketing team writes the captions, ships a retrofit page per battery brand (Powerwall, Sonnen, BYD, Goodwe, Enphase IQ), runs ads filtered by existing inverter brand, drafts the 'will my Fronius work with a Powerwall' explainer, and posts every blackout-test commissioning. You upload one photo per battery, approve the week, get back on the next install.

The battery market is a retrofit market, and the original installer has the head start

The reality

Battery installation in Australia in 2026 is mostly a retrofit game. Hundreds of thousands of homes installed a 5-10kW solar array between 2018 and 2022 when feed-in tariffs were still 12-15 cents, and now those tariffs have collapsed to 3-5 cents and a battery suddenly pays back inside seven years instead of fifteen. The customer is googling 'Tesla Powerwall installer near me' and 'will a Sonnen work with my Fronius', not 'solar installer'. Two structural problems. First, the original installer who did the array five years ago has the head start: they have the customer's email, the as-built drawings, and the inverter brand on file. If you're not in front of that homeowner when they start researching, the original installer wins by default. Second, the existing-inverter compatibility question is the whole sale. A Powerwall is AC-coupled and works with almost any existing inverter; a DC-coupled battery needs a hybrid inverter swap that adds $3-5k to the quote. The customer doesn't know this, but the website that explains it clearly wins the lead. Then there's the new layer: VPP opt-in (Amber Electric, Powershop, Reposit), where the right battery on the right tariff plan pays the customer to discharge during peak events. The installer who positions for VPP-ready customers gets the educated, high-margin lead.

What good looks like

Good solar battery installer marketing is a retrofit-focused page library, a compatibility-first lead form, and a VPP-ready trust spine. The page library needs one dedicated page per major battery brand: Tesla Powerwall 2 and Powerwall 3, Sonnen and sonnenBatterie, BYD HVM and HVS, Goodwe Lynx Home, Enphase IQ Battery. Each page leads with the existing-inverter compatibility matrix (this battery works with Sungrow X, Fronius Y, SolarEdge Z, Enphase Q), names the kWh capacity options, and calls out blackout backup capability and AC-coupled vs DC-coupled clearly. The lead form asks for the existing inverter brand and array size up front, so you can pre-qualify the quote. The trust spine is the CEC Battery Endorsed installer badge above the fold, the DNSP grid-connection approval handling called out as part of the service, and a 'will my existing system work with a battery' explainer page that ranks for exactly that long-tail search. Then a VPP-ready hub with Amber Electric, Powershop and Reposit tariff comparisons that pulls in the educated, high-margin buyer. Get this right and you win retrofits before the original installer rings back.

The original installer has the customer file
Whoever installed the array five years ago has the email list, the as-built drawings, and the inverter brand on file. If you're not visible when the homeowner starts researching a retrofit, the original installer wins by default.
Existing-inverter compatibility is the whole sale
Powerwall is AC-coupled and works with almost any existing inverter. DC-coupled batteries need a hybrid inverter swap that adds $3-5k. The customer doesn't know this. The site that explains it clearly converts the quote.
VPP-ready customers are the high-margin lead
Amber Electric, Powershop and Reposit pay homeowners to discharge during peak events. The right battery on the right tariff actually pays the customer. The installer who positions for VPP gets the educated buyer.

Caption from this morning's Vaucluse retrofit

"Vaucluse retrofit commissioned this morning: 13.5kWh Tesla Powerwall 3 AC-coupled to a 2019 Fronius Primo 8.2kW that the customer thought she'd have to replace. She didn't. Powerwall 3 sits next to the existing inverter, taps in on the AC side, no roof work, no panel re-string. Blackout test ran a full kettle and fridge load for 90 seconds before grid restored. She's now on Amber Electric and the Powerwall will discharge during peak events. Original installer quoted her on a full inverter swap. If your installer is telling you the inverter has to go, get a second quote." Drafted from the install photo. You approve, it posts.

Six agents, working in your accounts.

Account Lead, Web, SEO, Advertising, Social Media, and Content. One platform, one bill, you approve the work.

Account Lead

Builds your annual plan around the retrofit reality: which battery brands you actually stock and install, the existing-inverter brands you target (Fronius, Sungrow, SolarEdge, Enphase), and whether you push the VPP-ready hub at Amber Electric and Powershop customers. Briefs the other agents so the retrofit pages, the compatibility ads, the blackout-test social posts and the VPP content all push at the educated, high-margin customer instead of competing with the new-install installers on a generic 'solar battery' page.

Answers: the original installer has the customer file
Web Agent

Imports your existing site so you stop paying for hosting plus a CMS subscription, and ships a dedicated retrofit page per battery brand (Powerwall 2, Powerwall 3, Sonnen, sonnenBatterie, BYD HVM, BYD HVS, Goodwe Lynx Home, Enphase IQ Battery) with the existing-inverter compatibility matrix, the AC-coupled vs DC-coupled explainer, the blackout backup wiring diagram, the CEC Battery Endorsed badge and a lead form that asks for the existing inverter brand. Two taps to push live.

Answers: existing-inverter compatibility is the whole sale
SEO Agent

Goes through your live site for what actually moves battery retrofit rankings: '[brand] installer [suburb]' H1s, existing-inverter-brand mentions ('works with Fronius', 'compatible with Sungrow') because customers really do search that way, solar-energy-equipment-supplier schema, internal links from each battery page into the VPP hub so the educated customer benefits from cross-page authority, and a Google Business Profile with CEC Battery Endorsed and every battery and inverter brand attribute ticked. Auto-applies the low-risk fixes.

Answers: the original installer has the customer file
Advertising Agent

Runs separate Google Ads ad groups per battery brand with existing-inverter filtering. 'Powerwall 3 installer [city]' with the Fronius/Sungrow/SolarEdge filter on the landing page. 'Sonnen battery installer [city]'. 'BYD HVM retrofit [city]'. Plus a VPP-ready ad group on 'Amber Electric compatible battery' and 'Powershop battery installer' to capture the high-margin educated buyer. Drops broad 'solar' bids that feed the new-install aggregator funnel. Meta runs the blackout-test video posts that build owned demand.

Answers: vpp-ready customers are the high-margin lead
Social Media Agent

Turns every retrofit and commissioning into a post: a Powerwall 3 AC-coupled to a 2019 Fronius in Vaucluse, a Sonnen retrofit on an existing SolarEdge in Hawthorn, a BYD HVM bank in a Hills District home, a blackout test running a kettle and a fridge. Builds the existing-inverter-compatibility trust signal that wins the customer worried about being upsold on a full system replacement by the original installer. You upload one photo per job, the agent drafts the caption in your voice, you approve.

Answers: existing-inverter compatibility is the whole sale
Content Agent

Drafts the long-form pieces customers Google in the retrofit research phase: 'will a Tesla Powerwall work with my Fronius inverter', 'AC-coupled vs DC-coupled battery for an existing solar system', 'Tesla Powerwall 3 vs Sonnen vs BYD for a 6.6kW system in 2026', 'how Amber Electric and Powershop VPPs actually pay back', 'do I need to replace my inverter to install a battery'. Two drafts a month, in your voice, that pull the retrofit-curious homeowner to your site before the original installer rings them.

The bottom line

Battery retrofit is the entire next chapter of solar in Australia. Hundreds of thousands of arrays installed before 2022 are now economic battery candidates, and the original installer has the head start. The way you win the retrofit quote is the compatibility-first page library, the existing-inverter-filtered ads, the blackout-test social proof, and the VPP-ready content that captures the educated, high-margin buyer. The installers who own this segment for the next three years are the ones who stop trying to win on a generic 'solar battery' page.

Agencies are too dear to ship a page per battery brand with an existing-inverter matrix and a VPP-ready hub for $3.5k a month. Tools are cheap but the compatibility matrix never gets built. In-House is the third option: for $299 a month the agents ship the retrofit pages, the inverter-filtered ads, the blackout-test posts, and the VPP content. You stay in the driver's seat, two taps to approve, minutes a day. Stop losing the next Powerwall 3 retrofit to the original installer because the homeowner never knew you exist.

Frequently asked.

I do battery-only retrofits, not new solar installs. Will the pages reflect that?
Yes, that's the whole positioning. Onboarding asks whether you do new arrays, retrofits, or both; Account Lead briefs the agents accordingly. If you're retrofit-only the homepage leads with 'battery retrofit installer', the suburb pages target 'Powerwall installer [suburb]' not 'solar installer [suburb]', and the content schedule skips the new-install topics. You stop competing with the aggregator-funded new-install installers on a search that doesn't pay back, and start owning the retrofit segment where margins are higher and the customer is more educated.
Existing-inverter compatibility is the make-or-break question on every quote. How is that handled?
It's the centrepiece of the page library. Every battery page has a compatibility matrix at the top listing the inverter brands it works with (Sungrow X series, Fronius Primo and Symo, SolarEdge HD-Wave, Enphase IQ7/IQ8) and notes whether the install is AC-coupled (no inverter swap) or DC-coupled (hybrid inverter required). The lead form asks for the existing inverter brand and array size up front, so you can pre-qualify the quote and the customer arrives at the site visit knowing whether the install is a one-day AC-coupled retrofit or a full hybrid swap. Cuts the quote-to-install cycle and your time wasted on dead leads.
VPP opt-in (Amber, Powershop, Reposit) is a real differentiator. How does the marketing surface that?
A dedicated VPP-ready hub that ranks for 'Amber Electric compatible battery', 'Powershop VPP installer' and 'Reposit setup'. The page explains how each VPP actually pays (Amber wholesale exposure, Powershop fixed bonus, Reposit grid-services revenue), names the batteries certified for each VPP, and walks the customer through the tariff economics. The Content Agent drafts 'how Amber Electric VPP actually pays back' and 'is a battery worth it on Powershop' explainers that pull in the high-margin educated buyer in the research phase. VPP-ready leads convert at higher margin because the customer has already done the homework.
The original installer always has the head start because they have the customer's email. How does the marketing fight that?
You can't get the email list, but you can be the first installer the customer finds when they start researching. The way you do that is the long-tail compatibility content ('will a Powerwall work with my Fronius') and the brand-specific suburb pages that rank for the exact retrofit search the homeowner types. Most original installers haven't bothered with retrofit-specific SEO because they assume the customer will ring them anyway. The installer who builds the retrofit-positioned page library wins the customer who Googles before ringing, and that's most of them.
Will the social captions sound like AI?
They will sound like you, because the Social Media Agent learns from your existing posts during onboarding and you approve every draft before it ships. You upload one photo per commissioning (the battery on the wall, the blackout test, the AC-coupled wiring, the kWh meter reading day after), the agent drafts the caption from what's in the photo (the battery brand and capacity, the existing inverter you retrofitted to, the suburb), you approve in two taps. Voice updates with every correction.
Can I cancel if it isn't working?
Two taps, any time, no exit fees and no notice period. You keep your imported site, your battery retrofit pages, the VPP-ready hub, the compatibility content, and the Google Business Profile work. There is no $3.5k-a-month agency lock-in and no six-month minimum.
