Hybrid inverters Vs bi-directional/smart EV chargers

I have read that in order to support V2G or V2H I need a bi-directional/smart charger.

I have the following question:
Can I not go directly from a hybrid/smart inverter with DC to the vehicle (possibly with a MPPT in between if not already provided by the inverter). This way I will avoid the additional charger.

Basically I use the car like I would use a battery with hybrid inverter. For a battery I do not need a separate charger.

This cannot work as the EV batteries are generally very high voltage (300 to 500V DC) and most hybrid inverters are designed to work with 48V battery systems.

The other problem is that in order for a hybrid inverter to operate with a battery, it needs to be able to communicate with the battery BMS using the CANbus system.

Which electric vehicle are you using?

Thank you for your quick reply. As you can see I am quite new to the topic.

I do not have an EV yet. I am looking at VW ID4. Waiting for their V2H implementation, which is supposed to arrive end 2022.

It is a pitty that I have to convert from DC to AC in the inverter in order then to convert again in the charger from AC to DC losing every time 5-10%. When i go back from vehicle to home I convert again DC to AC.
Are there not DC-DC converters which can convert from the PV voltage to the car battery voltage.

There is only one specialised inverter (that I know of) from SolarEdge which can charge directly from a solar array.
