Where do you think halfrods get them from, wake up.
What in heavens requires a 3000w inverter.4 x 35A. fuses in my renogy inverter blew ( probably from steam getting in bare wires ) the strongest we had available were 30A jeff replaced them and it works perfectly, couple of weeks later some 35A from a boxed set were available so opened it up to replace them but visually the new 35A ones were less substantial than the 30s so left them in, i intend to purchase a new 3000A inverter when i return & will replace the 30s & carry that inverter as a spare
