Is the MPP Solar PIP-GK 3024 supposed to be able to charge LiFePo4 batteries with grid power?

I have this solar charger inverter and have recently also acquired a diesel 4kW generator for the days when it is only raining and very little sun reaches our panels.

However, when I connect the output of the generator to the AC-grid-input of the solar charger-inverter, it only offers pass-through AC power, and does not attempt to charge the battery bank at all.

This is highly disappointing :-/ so I am now trying to understand
a) if my expectations/assumptions are wrong,
b) if there is something wrong with the generator,
c) the MPP, or
d) if I simply need to bypass the MPP and just charge the batteries directly (would need to buy a LiFePo4 charger, perhaps 100+A as my battery bank is about 500 Ah 24 V.

Any help highly appreciated, including pointers to previous posts here on the forum, as I cannot seem to get the search to function.

I could not find the specific PIP-GK 3024 manual.

If it has the same “software” conventions as LV then Menu Option 2 and Menu Option 12 plus another # I can’t recall atm are where you enable/disable utility or generator charging. And there’s configurable charging amps available.

If you explore your manual you should be able to program your desired operating conditions.

Post link to manual.
Looks like it has a 60a utility charger.
THD of generator could be keeping the inverter from fully connecting to it.
