Discharge battery with constant current

I got acquainted with Victron Energy products and found that you can transfer energy from the battery to the 230V network using your devices.

I am asking for help in solving the following problem:

I need to discharge 12 V and / or 24 V batteries and transfer energy to 230V / 50 Hz.

We will not use any energy receivers, only the energy return to the 230V network.

Because these are batteries with different capacities, we want to discharge with a constant, programmable value. The range of discharge currents on the battery side is 10 to 200 A.

The value of the discharge current must be set by means of a software and digital input (e.g. USB or LAN), or set by voltage via an analog input, providing DC voltage (e.g. in the range 0-5Vdc, or 0-12Vdc).

Is it possible to use this type of battery discharge method using your devices?

If possible, please provide these devices and their connection diagram.
