Chain Boulder 15s to a Genasun controller

I'd like to chain my two Boulder 15s (no USB) to a Genasun solar controller to charge a LiFePO4 battery.

-Does the "chain" feature connect the panels in parallel?

-Is there an adapter available that would connect to the output plug and terminate in two wires to connect to the Genasun?

-What is the polarity of the plug?

-Would a blocking diode be necessary for the chained panels?

Thank you!

    Hi @PilotMike,

    The chaining feature does chain the panels in parallel.

    We don't have any cables that go to bare wires unfortunately.

    The pin on the inside of the 8mm port is positive and the external metal is negative.

    The panels already come with a diode for back flow. No need to add that to the panels.
