Hi crazy cut06: google freesunpower.com, everything you need to know on how to hook things up these guys have the best how to solar site out there that I have seen and I have visited 100s and good luck with your solar project!!! ;D

Hi Dr,
Thank's for the link, but i don't have much time reading, that's why i'm asking help here from solar experts with their own experience on connecting solar array for a grid tie inverter.... ;D


Regards

Hi Magluvin: thank you for your response! The picture isnt really clear enough to show my concern, the reason I am having trouble accepting this is because that center post is not hooked up to anything  EXCEPT the diodes. I thought the purpose of a diode was to prevent the electricity from flowing backwards into the panel FROM the batteries? Actually the electricity from the panels would first go to a charge controller and  from there to the batteries. I watched a tutorial on making your own solar panel, and the guy was very specific about putting a single diode between the positive side of the last cell tabbing wire and the output lead ???  These are new panels that just came from the factory, so you would think they got it right!!!

Hey Doc

So, those wires in the picture are the panel wires coming into the controller?

Putting the diode, as you were told, in series with the panels is usually because the panel will draw from the battery when the panels are in the dark, in simple circuits where there is little more than the panel, diode and battery, like a solar charging flashlight. But I would think that a controller would handle all that without the need for little extras like that. Maybe some do, maybe some dont.

The + and - designations in the pic, did you write that on there of is that the way it comes? I thought about the 2 diodes in series using the middle terminal between them. It may be that 2 are used in series for Peak Inverse Voltage reasons and putting them that way doubles that reverse voltage. Why not use just higher voltage diodes? When your making millions of devices, saving pennys count. ;)

I dont know what the unit in the picture is. Any documentation come with it?
