Hey all, I'm sure this has all been discussed before but I still just want to be sure I'm getting everything correct
This is my first solar set up and I'm looking to figure out a fuse point between my panels and my Growatt 24v 3000w All in one
SPECS:
Rated Power: 250W
Open circuit voltage (VOC): 37.3 V
Max power voltage (VMP): 30.1 V
Short circuit current (ISC): 8.78 A
Max power current: 8.31 A
Maximum system voltage: 600V (UL)
Fuse Rating: 15 A
IP65 Junction Box w/ standard solar connectors
Frame: Anodized aluminum alloy
Weight: 44 lbs
Dimensions: 1640 × 990 × 50mm (64.56 × 38.98 × 1.97 inches)
I'll be doing a 3s2p setup, so my array will be 120 Volts and 17 Amps. So if I have it right, I will be exceeding the panel's fuse rating of 15 Amps.
So what kind of fusing would you guys recommend? I think anything between 20 and 30 amps will work so I have size down, but the type of fuse is more where I'm confused. Should I do in-line fuses on each of the branches? Or a circuit breaker right before the AIO? ANL? What would you guys recommend? Brand names would be appreciated too -lots of bad reviews out there its hard to know what to trust.
Thanks!
