The MPPT 100/20 instructions tell me I need a 30Amp fuse. I'm wiring the MPPT through a Lynx Distributer but can't seem to find a 30Amp Mega fuse anywhere and get the impression they don't go as small as a 30Amp. Am I missing something here? I'm using 4mm2 wire between the MPPT and Lynx on a 1m cable run.
