Inverter fuse with lithium battery

[ridgy]

Just replaced by house batteries with lithium and have replaced the main fuse with a 250A class T fuse going to the busbar.
I have an inverter connected to the busbar which currently has a 250A megafuse on it.
Should this also be a class T fuse or can I keep the mega?

Mega fuse is fine there.
