    I want to know what size of DC MCB is required for 250W 24V Solar Panels X 4 connected to an inverter 1600 VA having 200Ah 12V x 2 Batteries?

    How do i size my MCB based on the panels?

    Look on the back of the panel, there is a sticker attached, or should be, and it will indicate the recommended  Amperage for the breaker
