    Description

    This MC4-compatible adaptor with a 10 A blocking diode lets you connect multiple solar panels in parallel to a single solar charge controller while preventing reverse current.

    • Connector type: male MC4-compatible plug to female MC4-compatible socket — fits standard PV cables.
    • Rating: 1000 V DC, 10 A DC.
    • Use case: connect several panels in parallel (common positive and common negative) to one charge controller.
    • Prevents backflow of power from battery to panels, especially useful with mismatched panel sizes or shaded panels.
    • Also usable as a blocking diode for a single panel to stop battery discharge at night.
    • Suitable for mixed series/parallel arrays when system voltage and current remain within 1000 V / 10 A limits.
    • Fully waterproof for outdoor use and easily disassembled for diode replacement.

    Compatibility/care: fits MC4-compatible PV cable ends — always ensure the array and controller do not exceed the adaptor's 1000 V, 10 A DC rating and reseal correctly after any maintenance.
