Luxpower-Gen settings

Hi! I’m looking for some advice

I have a luxpower sna us 6000, recently i connected a generator but could not make it charge my batteries.

I’m using a 7k Honda generator and eight Xterra 48 V 400 batteries. My battery settings are set as Lead-Acid. They charge perfectly from the pv but I cannot make it charge from the gen, it’s a manual gen so i turned it up and nothing happened.

My batteries were at 52 V, and i set my charging start voltage at 49 V.

Does anyone know what I could do? I’m pretty sure the wiring is okay and settings, but simple there’s something not working.

@Svarky might be able to point you in the right direction.
