FAQ

Q: What fuse rating for 50mm² cable?
A: Use a 250A–300A ANL or Class T fuse within 30cm of the battery positive terminal. Match fuse rating to the cable’s 210A capacity and the inverter’s maximum input current.

Q: Is 50mm² suitable for a 48V 5kW inverter?
A: Yes — a 5kW inverter at 48V draws ~115A continuous. 50mm² (210A rated) provides excellent headroom and minimal voltage drop for 48V systems.
