What fuse to protect Multiplus 2 5000

Hello all,

what fuse should be used to protect the 48V input of a Multiplus 2? Can it be a Megafuse 125A 58V in a Victron Lynx distributor or does it have to be an NH00 fuse?

Many greetings

Karli

Remember that the fuse protects the cables, it does not protect the equipment.

A 200A fuse is recommended for MPII 48/5000/70 along with 70mm² battery cables for short runs. A 200A 58V Mega fuse would be great.

Thank you very much for your answer.

Would there be any disadvantages in using a 125A Mega fuse with a 25mm2 or 35mm2 cable instead of the 200A fuse with a 70mm2 cable?


In normal operation the Multiplus never draws more than 4000 watts, which is about 80A plus maybe 15% for losses.
