This buck converter came up in another thread.   Here is a new thread for it.

It's a variable step down, specs say 20A.   It has a UART and is programable via modbus.

There are probably a hundred different vendors, here is one:

I use it to step down my 24V battery to 12V which I use for various things.

They are only $25 on aliexpress. Tempting but I don't know what I would want to remote control via power supply .

Add a microcontroller and program a poor man's MPPT...  As long as your PV array voltage is < 70V.
