Export Match (Solar Mode)

What is Solar Mode🌞🔌

Solar Mode allows your Indra charger to use excess energy from your solar panels (or other renewable sources) to charge your EV instead of exporting it to the grid.

How to Enable Solar Mode

In the Indra App:

Go to Settings
Select Electricity Supply
Set Solar Panels = Yes
Turn 'Use Solar' = On

How Solar mode works☀️⚡

Your charger uses an External CT (Current Transformer) to monitor energy export from your property.

When Does Charging Start?

When the charger detects an export of more than 1.4kW (≈6A) for over 1 minute, it will start charging your car using that excess energy.

Export of >1.4kW (6A) must be maintained for >1 min for a charge to start.

The CT measures export, not generation—This means your solar generation must exceed your home’s demand by at least 1.4kW for charging to begin.

Important Notes:

The 1.4kW limit is set by the EV charging standard BS 61851 and cannot be adjusted.
Indra has no control over this requirement.

Boost Mode 🔋

If you press Boost during a solar charge:

The charger will override Solar Mode and charge at maximum power until Boost is turned off, or the car is full.

Solar and Tariff Integrations

If you’re using a flex integrated tariff (like Octopus Intelligent Go or OVO Charge Anytime):

Solar charging will still work alongside tariff-controlled charging.
Example: If you’re generating 2kW solar and Octopus requests a 7kW charge, your car will use 2kW solar + 5kW from the grid.
You’ll only pay for the grid energy, not the solar.
