Hi all have been waiting for a nice day to fit a 80 watt solar panel for my new 155 ah battery,completely seperate system from the 110 ah and 60 watt panel already on van when i bought it.
Every thing going well ,new panel sylcaflexed on at 10.30 am so it has the rest of the day to adhere,all cables etc in place ....now i go to connect the MC4 connectors the pos mc4 from the panel goes to the mc4 negative cable to the controller and vica verca....
So have the factory wired up the mc4's wrong and what do i connect to the controller.
I have double checked all the cables,as both where black i initually put red tape at intervals down the pos so there could be no mistakes.
Now i'm in a quandry as to connections .as the mc4's have reversed the pos and neg i could easily connect pos to neg at the controller.
Have done all i can for time being also do i need to tape the mc4's to waterproof them they will be under the panel eventually.oh:
Thanks Dug.
