Hi
i am new on here, and new to solar. My goal is to get our small freezer on solar. I so, I have had my first go at a system using
3 x 120w solar panels in paralell
3 x 130w leisure batteries, sealed led acid in paralell
1 x automatic transfer switch
1 x Victron 100/20 charge controller
1 x. 1000w inverter
freezer uses 800w a day. This seems to be doing the job.
my biggest head scratch at the moment is fuses. I have a 100 amp between the battery and inverter, and 50 amp fuse between the charge controller and batteries. I am not sure if I need a:
* fuse between panels and controller
* fuses between inverter and transfer switch
* fuse between transfer switch and load, although the plug does have a 13 amp fuse in it.
also the cables on the batteries are car battery cables from Amazon but they are not the thickest ones (seems to be two sizes.
And to combine the 3 panels I’m using a 30amp junction box used in normal AC house electrics. Not sure if that’s correct or would give too much resistance etc.
So that’s where I’m upto!
