EV charging after first X kWh exported?

This page contains instructions for configuring
chargers with Charge HQ
Please refer to our
charger listing for details on supported models and charger specifications.

Some electricity tariffs provide a high feed in tariff (payment for exports) for the first X kWh (e.g. 10 kWH) then default to a lower price for any additional exports.

Charge HQ cannot automatically allow for a fixed quantity of exports before using any excess for EV charging. We only actively monitor solar exports whilst an EV is available to be charged, at all other times we don't actively track solar generation or exports. We do this to reduce the load and cost incurred by all parties to provide the online services.

If you would like to charge your EV from solar but still maximise the use of premium feed in tariffs with Charge HQ, you can try:

  • Setting a solar tracking margin of say 1 kW. This will cause EV charging to leave 1 kW of solar generation unused at all times that will be exported. Some experimenting and adjustment may be required during the year to find the optimum tracking margin.
  • Set a block out period so that each day no solar is used for a short period (e.g. 1 hour)
