What fuse type is best for Multi-plus II?

Hi there,

Which fuse type is best for fusing the Multi-plus II? ANL, MEGA fuse, CNN fuse, other?

I imagine a slow blow fuse would be better so that it withstands short spikes of current from the inverter for short periods. I'm thinking of going with the MEGA fuse as it seems they are slow blow where as the other aren't (or they vary)? Just wanting to get some advice as to weather this would be the best option?

Also wondering which fuse type would be best for fusing each battery? I will be running 2x UP2500 25.6V Pylontech batteries.

The 32V MEGA fuse would be just fine for the inverter circuit. I also use those.

No need to fuse each of the Pylontech batteries, they have their protections built in. Just link them together as described in the manual.

Than you. This may seem like a dumb question but if I have a Smart solar MPPT 150/100 TR. Should the fuse in the DC output positive cable be 100A?
