Free Battery Fitness Score

Create your Battery Fitness Score

Screens self-consumption fit with solar (existing or modeled). Not a full tariff, incentive, or payback analysis.

Net interval-data file

Choose CSV or XLSX

Timestamp plus signed net kWh, or separate grid import and export kWh columns. Positive signed values must mean grid import. CSV, XLSX, XML, or ZIP · Max 30 MB.

Do you currently have solar?

Yes

Yes = use your system size. No = we model solar at your offset target, then score a battery.

Do you already have a battery?

Yes

Existing storage changes the meter profile and lowers confidence.

Blended electricity rate ($/kWh)

Used to value recoverable solar exports that offset later grid imports.

ZIP code

Used with PVWatts to model solar production for this location.

What happens next?

A strong score means the profile is worth taking to a qualified battery provider for pricing. Use the actual tariff, export compensation, incentives, and installed cost for a detailed savings and payback analysis.
