Free check · Perth, Western Australia
Send a photo of your Synergy bill and two or three screenshots from your battery app. We’ll tell you, in plain English, whether the battery is set up to match your plan — and what, if anything, to change.
For Synergy customers in WA. We never log in to your account or touch your system. You stay in control of every setting.
A photo or PDF of a recent Synergy bill, plus two or three screenshots from your battery’s app (the home screen, the mode or schedule, and the reserve or “backup” setting if you have one).
Our small Perth studio does the check, using AI tools to help read your bill and screenshots, and writes back by email. We aim to reply within one Perth business day.
If something is worth changing, you make the change yourself in the app. We include a simple way to undo it. Your next bill is the proof of whether it helped.
Home Plan (A1), Midday Saver, or the EV Add On — based on how your home actually uses power, not a generic guess.
For example: is it buying power from the grid at the expensive time of day, or holding charge when it should be topping up in the cheap window?
If you are in it, or thinking about it, we’ll explain what Synergy can do with your battery and what the credits are meant to be. If credits look like they’re missing, we’ll say so.
We’ll tell you who to go to first — usually your installer, then the battery brand, then WA Consumer Protection if you still can’t get a fix. For missing Synergy credits, we start with Synergy.
Synergy Midday Saver charges different amounts at different times of day. These figures are from Synergy, include GST, and apply from 1 July 2026. They can change.
The cheap window. A battery can often top up here, including from the grid in winter when the roof isn’t making enough solar.
More than six times the midday rate. This is the expensive window to avoid buying from the grid.
Home Plan (A1) is a flat 33.2621c a unit, plus 119.2419c a day. Midday Saver only pays off if your battery and your habits actually use the cheap window and dodge the peak. Source: Synergy’s Midday Saver and 2026 price pages.
A$4.99 one-off, not a subscription
If the free check finds something worth changing, you can pay A$4.99 for the full write-up:
the exact taps in your own brand’s app, a simple undo step, a check of your next Synergy bill, and draft letters if you need to chase missing Battery Rewards credits or a fault.
You only pay if the free check finds something worth fixing. There is nothing to pay on this page: if your check finds something, we include a secure Stripe payment link in our reply, and it is up to you whether to use it.
Fill in the form below. We store your details privately so we can do the check and reply by email. Nothing you send is public.
Your bill can include your name, address, account number, NMI and how much power you use. Please cover the personal details before you send it, if you can.
When you send a check request, we store: your name (if you gave one), email, suburb, whether you said you are a WA Synergy customer, battery brand, Synergy plan (if you chose one), optional notes, the bill file, up to three app screenshots, the time of the request, and a rough location of the request (country / city from Cloudflare, not GPS). We use those only to do your check, to reply to you, and — if you ask for it — to look at your next bill. We do not sell your information, and we do not pass it to installers or other businesses. We do not send automatic marketing emails.
Files and details are kept privately (not publicly readable). We delete them within 30 days of finishing the check, or within 30 days of the next-bill follow-up if you asked for one. If you want them deleted sooner, email johnong726@gmail.com and we delete them.
This is general information, not financial advice, and not electrical or safety advice. We are not Synergy, Western Power, or your installer, and we are not financial advisers or licensed electricians.
We never log in to your Synergy or battery account, and we never change your system ourselves. You make any change, or you ask a licensed electrician or your installer to do it. We will not suggest changes to safety settings, export limits or grid-connection settings.
A settings change can raise a bill if it is a poor fit for your home. That is why we keep advice conservative, include an undo step, and use the next bill as the check. Prices and Synergy rules can change. Always confirm plan details with Synergy before you switch.
