No guessing. A live workspace where you can choose the perfect battery for your home.

Your year, half-hour by half-hour

Use 12 months of your real electricity consumption. See your peaks, the base load, your weekend swing, not just a generic profile.

Every battery brand, side by side

We analyse over 170 battery models from every brand. Race them against your actual house to see which is best, ranked by the metrics that matter.

Your solar for your home

Instead of selling solar energy for nothing, pinpoint the solar sweet spot where you can get the most out of your battery.

Your tariff. Your savings.

Time-of-use, demand charges, controlled load, modelled against your actual plan, so the dollar figures are not industry averages.

Live quote checker

Compare any battery quote. We check the sizing, brand, and price to find the right answer for your home.

Independent. No kickbacks.

We do not sell batteries. We do not take referral fees or sell your information like quotes websites do.

People who'd rather see the real savings.

"Its super helpful to have a battery analysis based on my actual electricity usage (& factoring in for seasonality) rather than theoretical. Thank you!"

Adam

"The level of detail was excellent. An analysis of combined solar and a battery was invaluable."

Stephen

"I was really happy with the analysis. It was well-considered, well-written and really helpful. It confirmed what I thought about our consumption patterns and a battery."

FAQ

Things people ask.

No. We connect via CDR (Consumer Data Right), the bank-grade open-data framework. Your electricity provider hands us 12 months of interval data directly, no PDFs, no spreadsheets.

Battery analysis without solar still tells you whether time-of-use shifting alone pays off, and we can predict the solar performance for your roof if you're adding both together.

Paste it in. We compare it against the right size for your home, current market pricing, and red-flag terms. You'll know if it's a good deal in 30 seconds.

No. We don't sell batteries and we don't take commissions or kickbacks from installers. You pay us once for the analysis, and that's our only revenue.

We use your half-hourly interval data, your tariff, your roof orientation (if solar), and a year of typical weather. Results are typically within 5-8% of the first year actual savings.

Connecting your data takes about 3 minutes. The report generates in under an hour. You'll get an email when it's ready.
