    I have capacitor bank that charge to 300volts, and I’would like to make a
    cut off switch for it reaches its max charges. My plan was to make a 12 volt
    LED meter with an LM327, and a voltage divider that bring the 300 down to 1

    AN939 from Microchip for the voltage attenuation part. There are millions of more application notes apart from these.

    Why not using a simple projector to project the value on a wall or some thing?

    Get the reading from the house and feed it to a projector after suitable modification to it. You are all set to go about in this project
