Solat charge controller ISSUE

[aasimzee]

I am using this circuit theoretically it should work but on proteus its giving some issue. even if i dont give anything on gate of mosfet still current flows through it.
Please check if there is any mistake in it. I have used two batteries to check result.

Hi,

theoretically it should work but on proteus its giving some issue.

Is this a detailed error description?

if i dont give anything on gate of mosfet still current flows through it.

NanoAmperes? Kiloamperes?
--> Tell us the value if the current. And tell us V_gs.
