Just about got everything I need for my instal apart from some dry weather and fuses!
Depending on where I go for information I'm left a little uncertain about fusing needs. Should I fuse between the panels and controller, some say yes and some say no.
If I do need to fuse should the fuse be at the panel or controller end?
More importantly what fuse size and should I fuse both positive and negative inputs?
I've got two 150w panels which will be connected in parallel.
Panel specs:
Max V 17.8V
Max A 8.43A
Open circuit V 22.3V
Short circuit A 9.1A
Controller is the one used by Andy, Techno 100. 25A/300W MPPT by Maximum Solar
Understand the need to fuse between the controller and fuse close to the battery terminals. I've got 2 x 100ah (traction type I believe) batteries for leisure use. I also have a pair of midi fuse holders to fit, but what size fuse do I fit there?
All advice gratefully recieved
