I have a 2013 hilux with the BCDC 1225D connected to a deep cycle lead-acid battery which seems to be charging well. I have a 160 watt flexible kings solar panel that I want to connect to the BCDC 1225D as well, but want to check if I'm going about it the best way. The solar panel has open-circuit voltage of 21.9V, short-circuit voltage 9.37A, voltage at Pmax 18.3V and Current at Pmax of 8.75A.
My understanding is that I should connect the BCDC 1225D yellow wire to the positive input of an Anderson plug, then connect the positive wire from the solar panel to another Anderson plug, then connect these 2 Anderson plugs. I would then earth the negative lead of the solar panel via another Anderson plug to the negative terminal of the auxiliary battery. Could someone please advise if this is the correct approach?
