I am getting to the installation of my system. I have 6- 200W panels in parallel of 3. My MPPT is a victron 100/50. I calculate my voltage will be around 60V and 20a. I was going to put a fuse between the controller and panels. I was going 25A setup. Also, I was going to run a 50 amp between the mppt and batteries? Sound about right? Any recommendations on a source for the fuse or breakers?
I also have two 12V 220Ah batteries I am going to run in series to run 24V. They are the gel batteries. Do I need to vent these? Also, will I need a battery balancer you think?
Thanks.
