I'm building a small solar system that will hopefully lead me to building a larger one later on and I have some questions. I have four 100W solar panels. I have a 100V 40 amp charger. I have a 700 watt pure sine wave inverter. I have two 12V lead acid batteries that each have an ah rating of 106.

The solar panels are 100W, have 20.4 optimum operating volts and an optimum current of 4.91 amps.

I'm going to run the panels in series so if I'm figuring right it should be 400 watts, 81.6 volts and 4.91 amps. If I use 10 gauge stranded wire that should take me a long way from the panels to the controller, correct? Any idea what the max distance would be? The inverter came with 6 gauge cables so I should be able to use 6 gauge cables across the battery also, correct? The batteries will be ran in parallel because the inverter is for 12 volts only.

Since the panels have an output of 4.91 amps then would a 10 amp fuse be ok for that? The inverter watts divided by 12 volts is 58.33 so would a 60 amp fuse be ok from the inverter to the battery?

Would a 100 amp fuse between the battery and the inverter be ok?

Can somebody point me to some connectors that would work with my solar panels? Are there any particular fuses that would work best with this application?
