Solar Panel 30 Amp Blocking Diodes

Blocking diodes are designed to connect solar panels or arrays in a parallel configuration. They can protect panels against reverse polarity currents in parallel solar arrays as well as reduce the risk associated with the higher voltages found in an equivalent series array.

Each diode is rated at 30A - this should be more than sufficient for most small scale off-grid setups but can be checked by finding the maximum short circuit current of each connected panel. The diodes also have universal MC4 plugs, with their respective male and female polarity making it impossible to wire incorrectly. They are also water resistant for continuous outside use.

Perfect for any off-grid setup, outbuilding project, automated greenhouse, campervan, caravan, motorhome, RV or fifth wheel.
