Supported Configurations

Charge from gross solar production
EV charging can be matched to gross solar production for all Internet connected Solax solar Inverters.

Charge from excess solar production
Where an optional grid meter is installed, underlying energy usage in the home is taken into account allowing charging to match only the excess solar production.

Grid Monitoring Options

If you would like to match your EV charging to excess solar production (rather than gross solar production) you will need a separate meter installed to monitor home energy consumption. For Goodwe inverters, your options include:

Solax Grid Meter
Supplied by Solax this monitor integrates directly with the Solax inverter provides visibility of all of your home energy consumption in the Solax app.

Stand alone solar and grid monitoring
A separate solar and grid monitor can be installed to provide Charge HQ with a compatible solar data source.

AC Coupled batteries
Users with a Solax solar system that also have a supported AC coupled battery can rely on the battery integration which will include grid monitoring. A separate grid meter for the solar inverter is not required in such cases.
