Smart tariff EV charging without home energy conflicts

When EV charging is cheap, it can still be operationally expensive if it competes with battery reserve, heating demand or export value elsewhere in the property.

How sign-up works

This already runs in real homes, and supported homes can sign up today.

1app.energy is built around conflicts like this one. Start by choosing your inverter; supported homes create an account straight away.

Start with your inverter

Supported Solis, LuxpowerTek, Sunsynk and SigEnergy homes create an account straight away; other setups join the compatibility list.

Combination creates the value

Whole-home value comes from how devices work together, not from any single device in isolation.

Add your devices during setup

EV chargers, heat pumps, hot water and your tariff are added after sign-up, and each one shows what it supports.

Best fit

For households using off-peak or intelligent EV tariffs who need the charger to work with the rest of the home, not against it.

Friction today

  • The charger can consume the same overnight window the battery wanted.
  • The car can look cheap to charge while forcing expensive daytime import later.
  • Most apps optimise the charger but do not explain the whole-home result.

What improves

  • Separate EV load from the rest of the house so its cost and timing are visible.
  • Understand overnight charging in the context of battery reserve and next-day solar.
  • Reduce hidden charger-versus-battery conflicts in smart tariff homes.

Typical workflow

  1. 1

    Connect the tariff and charger context alongside any battery or solar devices.

  2. 2

    Use daily reporting to compare charger behaviour against total import and net cost.

  3. 3

    Tune the setup around real whole-home outcomes rather than individual device wins.

Smart controls that usually fit this problem

These mode pages explain what battery strategy tends to work best once this use case shows up in a real home.

Smart controlRecommended

Autopilot

The best starting mode for most homes. Autopilot charges when power is cheap, keeps battery back for the home, and can export spare battery power when prices are high.

Smart controlHome-first

Home First

A simpler home-first mode. It runs the home from your own solar and battery first and avoids automatic battery export.

Smart controlTariff-window charging

Time-based Control

A simple schedule-based mode. Time-based Control charges the battery during your cheaper tariff periods until it reaches the battery target you set.
