my-PV AC•THOR

← Heating Sponsor token required

Use the local web interface of AC•THOR to set the value "Power timeout" to a value slightly higher (e.g. + 5s) than the interval time of evcc. If the heating element at the controlled output has < 9 kW, the scaling factor has to be calculated as follows: scale = 9000 / nominal power of the connected heater.

Operation mode M3: 9 + 9 kW with an additional heater connected to the relay output is supported. Without load measurement using my-PV meter, the "Load at relay" setting in the local web interface of the AC•THOR must be set to match the nominal power of the heating element at the relay. If the heater at the controlled output has < 9 kW, AC•THOR firmware a0022200 or higher is required and the value for "Load at relay" must be converted using the scaling factor as follows: Load at relay = nominal power of the heater at the relay * scale factor

Supported features

Built-in meter: Support for an integrated meter. Availability may vary between models.
