Trying to knock-up another solar panel using off the shelf components, feeding into my existing 20a Victron BlueSolar.
The screw terminals on the controller will only accept 1 pair of cables. I need to have tails with a (effectively) a permanent connection for the roof mounted panels and a 'connect when needed' for the third, deployable, panel.
I have 2x100w (or are they 125w? will check) wired in series with "4mm2" cable thro' to the controller. 1 joint at cable entry gland, 1 fuse in +ve
"4mm2" doesn't conform to an AWG standard.
10AWG=5.26mm2
12AWG=3.3mm2
The connectors available from amazon.es within the available timescale (next Tuesday!) are 12AWG.
I propose XT60 connectors:
One end removed and bare wires connected to Victron. Kept as short as possible and connect to one of these ...
To get the two-into-one feed. Then solder XT60 conns onto the existing panels' wiring and the portable's fly-lead.
What does the hive-mind think?
XT60's are rated for 30a, this lash-up will be passing <18 at most. I think.
I could, of course, use domestic choc-bloc connectors to get the 2-into-1 but that's a bit too bodgy even for me ...
