    Hi there

    I came across a 3000W 24V DC to 230V AC inverter, but unfortunately it has blown all the mosfet transistors. It seems to be a quite fancy inverter for its seems to have automatic switching and charging.
    I don’t need all of that, al I want is to convert it to a plain and simple inverter, I will connect it manuallyand will charge my batteries self.

    What I need is a very simple circuit to add to the transformer, but please bare in mind that I live in a small town in South Africa, thus meaning I don’t have access to electronic shops.

    I do hope that someone can assist me.
