Hi there,

what I need to change to support 300V input from my photovoltaic panels and 40A current to battery?

Just different inductor and MOSFETs?

Thank you.

That would be a completely different design, probably with a two-phase power stage.

I see... And what about an idea of an addon module for higher voltage and load, isolated via optocoupler?
