Hi All,
I have a 750 watt array coming into a 60a controller feeding a 24v battery bank leading to a 24v 1500w inverter. I have had lots of conflicting advice with regards to the size and type of fuses I need. I have 4awg wire between the controller and batteries (about 3 feet) and 4awg between the batteries and the inverter (about 8 feet). The inverter Compay (GoPower) suggests a 110A type T fuse. The cable manufacturer suggests a 150A fuse with any 1500 watt inverter. I haven't been able to find any info about what size to put between my controller and battery, but I did just pick up a 150A DC surface mount circuit breaker because someone suggested it. Thoughts? Any reason why I couldn't use a circuit breaker rather than a fuse on both connections (makes disconnecting when required easier).
I'm also wondering why the fuses would be more like 120A given that the maximum surge is 2400W at 24v. Perhaps because a discharged battery might need to push more current?
Finally, can I run the ground wire from the inverter into the same ground (leading to buried grounding plate) as my controller?
Thanks!
