ARGOFET - reverse current flow?

DIY
1

I have the output of a solar controller (from panels) feeding the input of an argofet, which subsequently charges three different 12V batteries; the batteries are all independant form one another other than they share a common ground with the arfofet and the solar controller.

If one of the three batteries also gets charged independantly of the argofet, and say got to 14V and the other two batteries were 12.5V, would there be any reverse current flow from the higher voltage battery through the argofet to the other two batteries, or do the internal diodes prevent this? Is there a point at which the voltage gradient would so great it would overcome the internal diodes?

The Argofets have a much higher breakdown voltage in the opposite direction than the small difference you have at the moment. So don’t worry … that’s what the Argofet was developed for.
However, the voltage difference between your batteries should not exist if they are all connected.

If they are all floating… but if they have different loads, then…

Absolutely correct :+1:… thank you … not in the load, of course …

I meant when loading
