I think I've finally got all my parts, and I'm about to put it together.
I have a single Renogy RNG-100D-SS (Voc 24.3V, Isc 5.21A, Vmp 20.4V, Imp 4.91A)
The panel came with a Wanderer 10A Charge Controller (12v/24v 10A, maximum 12awg cable due to terminal size)
I found a 12V 35Ah AGM battery
I have a 410W inverter
Questions:
Is my charge controller able to handle this system, specifically the inverter load (estimated at ~33A)?
Do I need a dedicated BMS, or does the charge controller act as the BMS?
Are my fuses sized correctly? My understanding is that a fuse needs to be rated OVER the expected nominal current going through the wire, but UNDER the maximum rated current for the cable... e.g, I expect 10A from my CC to my battery...if I have a 5ft 12awg wire, would a 20A fuse be correct? (calculation tells me I need a 15A fuse; the cable should be able to handle up to 25A @ 6ft with a 3% voltage drop)
Where do I connect the inverter to the system? I believe the inverter will draw about 33A nominal. If I connect directly to the charge controller, I need to use 12awg, which supports maximum 25A. If I connect directly to the battery, I could use my 6awg which can handle 50A+ at the lengths I'm working with, BUT would still technically be on the same battery leads on the charge controller...do I need to worry about that current damaging the charge controller? or blowing my 20A fuse between the charge controller and battery?
