Although my-PV does not produce charging stations, there are various options for compatibility.
The EV Function is to be used exclusively for direct compatibility!
Direct compatibility with charging station
Direct compatibility exists if my-PV also performs the energy management of the charging station.
However, it should be noted here that the power controllers from my-PV can only modulate the
power on electric resistance heaters. This means that they never take over the power modulation of
the charging station! However, the energy management system can tell the charging station how
much photovoltaic surplus is available. As soon as the available charging current exceeds the limit of
6 amps, the charging station can adjust the power for vehicle charging accordingly. Although my-PV
does not actually consider itself a Smarthome manufacturer, this type of energy management is
possible with some types of the Keba brand.
More information on compatible charging stations can be found
Indirect compatibility with charging station
Indirect compatibility already exists when a higher-level energy management system has control
over all consumers. For example, if a smarthome is able to control a charging station in addition to
providing power to my-PV. In some cases, such systems also allow prioritisation of the different
applications. Examples of such indirect compatibility include the SMA Sunny Home Manager, E3DC or
Solar-Log. In this case, the my-PV device has nothing to do with the charging station. From my-PV's
point of view, the wallbox manufacturer openWB also falls into the category of higher-level energy
management, because the entire control and regulation strategy of the consumers is the
responsibility of openWB, while the my-PV devices are only given the power output.
With both indirect and direct compatibility, an intelligent system coordinates the heat applications of
my-PV and the charging station. There is also a third possibility.
Compatibility with charging station without common energy management.
This concerns the case where there are both applications, but they do not interact intelligently with
each other through any energy management. This is the case when, for example, an inverter
manufacturer can control its own charging station with solar power, but has not implemented the
my-PV application as part of the energy management in its control system. In this case, my-PV
exists as a separate controller quasi parallel to it and uses the PV surplus according to the power
measurement from the house connection. It can happen that the my-PV application does not leave
any surplus for the charging pole.
However, the interaction with the charging station is coordinated with the AC ELWA-E from firmware
00205.00 and with the AC-THOR from firmware a0020800. The explanation can be found in the
section "Interval target value" in the chapter "Control settings", as well as in the section "EV
Charging station power" in the chapter "Measured value settings".
