Hey there people,
I am currently designing my first solar system for an off grid cabin, with 2s4p due to shading (each panel 230W, Voc 37V, Vmp 30.3V, Isc 8.2A, Imp 7.6A, Max fuse rating 15A).
I was originally planning on connecting each string to MC4 15A inline fuses, and then using three pairs of these 2 to 1 connectors (https://www.solamart.com.au/product/mc4-y-connector-2-to-1-pair-genuine-mc4/) to join all to 1 output to disconnect and then Victron 150/60 mppt charge controller. I then learnt of combiner boxes and am now wondering if that would be the better option here?
I was looking at Eco-worthy combiner boxes (https://www.amazon.com.au/dp/B01N96GJFT/ref=emc_b_5_t?th=1) but wondering if the 10A fuses would be suitable, or would I need to opt for 15A fuses?
Any opinions or advice would be greatly appreciated!
