I have four 150 watt Solar panels which I am planning to connect in parallel to increase the current output. The spec of the panels are:
Nominal Maximum Power (Pm)
150Watts/12VOpen Circuit Voltage (Voc)
22.50VShort Circuit Current (Isc)
8.81AVoltage at Maximum Power (Vmp)
17.96VCurrent at Maximum Power (Imp)
8.36AMaximum System Voltage
1000VLink:
https://www.microtekdirect.com/product/microtek-pv-module-150w/I am just a bit confused where the location of fuse should be.
Of all the panels, should I wire all the positives and negatives respectively first, and then just drop a single fuse (may be of 35A/40A) in between the charge controller and this parallel panel connection. Or should I first drop a fuse for each panel first before making a parallel connection and then connecting it to the charge controller?, thus requiring one fuse per panel.
I also wanted to know what should be the amp rating of the fuse in each of the case mentioned above?
