Is your battery actually paying off?
Upload one power bill and see what your battery is likely saving you. Then check whether your electricity plan and virtual power plant are the right ones for how your home really uses energy.
Independent. We don't sell electricity, and we never control your battery or devices: we only read data.
No battery yet? See what one could save you.
Three answers, from your own data
What your battery saved
Bills from before and after your battery, matched by season, plus daily data straight from FoxESS or Sungrow systems.
The cheapest plan for your home
Every eligible plan priced against your half-hourly meter data, not an average household.
Whether your VPP is worth it
Credits weighed against how often the provider uses your battery, how low they can drain it, and exit fees.
Then we keep watching
Still on the cheapest plan?
Early each month we re-price the plans in your state on your own usage and email you if a cheaper one appears.
Battery alerts
If your battery stops discharging, isn't charging from solar, or goes offline, we tell you, so a fault doesn't quietly cost you for months.
Guides
Short, independent guides on VPPs, time-of-use plans and getting more from your battery.
