Energy rates & financials

If you set energy rates in the app, the dashboard can show financial insights: cost of grid import, export credit, net cost, and savings. Rates are configured per device (inverter).

Where to set rates

Section titled “Where to set rates”
  • Menu → Account → Energy Rates (or “Set import/export rates”), or
  • From the dashboard, use the Configure energy rates (or “Set rates”) prompt in the financial section.

The form opens for the currently selected device. If you have multiple inverters, switch the device in the menu first if you want to set rates for another one.

Simple rates (single import & export)

Section titled “Simple rates (single import & export)”
  • Import rate — Price you pay per kWh for electricity from the grid (grid → house). Enter the number, e.g. 0.25.
  • Export rate — Price you receive per kWh for electricity you send to the grid (e.g. feed-in tariff). Enter the number, e.g. 0.08.
  • Currency — Choose your currency (e.g. GBP, USD, EUR). The app uses it for all cost and credit labels.

The app uses these to compute:

  • Import cost — Grid consumption × import rate (for the selected period).
  • Export credit — Export to grid × export rate.
  • Net cost — Import cost minus export credit.
  • Savings — Value of self-consumed solar (and optionally battery) at your import rate.

Peak / off-peak (time-of-use)

Section titled “Peak / off-peak (time-of-use)”

If your tariff has peak and off-peak periods:

  • Enable Use peak/off-peak (or equivalent) in the energy rates form.
  • Set Peak period — e.g. start and end time (e.g. 7:00–23:00 = peak, rest = off-peak).
  • Peak import rate and Peak export rate — Rates during peak.
  • Off-peak import rate and Off-peak export rate — Rates during off-peak.

The app splits your consumption and export into peak and off-peak (using your timezone from Account) and applies the correct rate to each. Financial insights then show peak vs off-peak breakdown where relevant.

What you see on the dashboard

Section titled “What you see on the dashboard”

  • Financial insights section (when rates are set) shows:

    • Today’s (or period’s) import cost, export credit, net cost
    • Savings from self-consumption (and optionally battery)
    • For peak/off-peak: breakdown by period

  • Energy flow and charts are unchanged; only the financial numbers depend on your rates.

Updating or removing rates

Section titled “Updating or removing rates”
  • Open Energy Rates again and change the values, then save. To “turn off” financials, you can set rates to zero or leave them blank (behaviour may vary; the section may hide if no rates are set).
  • Rates are stored per device; switching device loads that device’s rates.
