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.
