Solar Wire Size..??? Fuses on panels...??
Ok, ready to install my solar system and I need to buy wire to go from panels to the solar controller Two, 140W panels, wired in parallel Here are the specs on the panel: The wire lengt...

My basic wire use here in the AMCOR very flexible 4AWG cable. For my panels I will run the 4AWG cable to a junction box close to the panels and then run smaller size cable from the the individual panels to the junction box.
I will want to use the quick disconnect cables at the panels so that they can be removed if needed... There are several install kits in the solar world that use the quick disconnect idea...
My goal for my upcoming solar panels will be be to produce at least 20AMPS of usable DC Current during high sun in hopes to re-charge my multiple battery bank to at least there 90% charge state before I lose the high sun. Then I can use the batteries for the next day/night run off the batteries...
I would love to have enough solar panels to re-charge my batteries to their 90% charge state in a three hour charge run but this is unrealistic cost wise to attain. My current battery banks want to use 52-53 AMPS DC current when first hit 14.4VDC charging voltage from the controller. This would require several solar panels in he setup since most 120WATT Solar Panels will only produce around 15-19VDC at 5-6 AMPS of usable DC Current. Just having a couple of these sized panels on the roof will take alot of hours of high sun to achieve this before your high sun goes away at the end of the day.
Just some of my thoughts here in my planning for solar panels to supplement my 2KW Generator run each day when camping off the power grid...
