I have a Victron energy Bluesolar Charge Controller MPPT 250|100 - Tr VE CAN.
I connect the solar panel input to the controller and output from the controller connected to the battery pack system. Solar input which iam getting is 98V and present battery voltage was 50V, both the voltages of solar and battery was showing in the controller screen but current is not flowing, what might be the reasons ?
I cross checked every possibilities, my doubt is, is there any fuse which lies inside the solar charge controller, is because of that it was restricting ?
But if i keep the rebulk-offset was too low might the charger will detect the drop in voltage and will restarts to charge the battery again as the difference was too low, might it will charge frequently.
Re-bulk restart voltage = Float voltage − Re-bulk offset.
If suppose float voltage is 54.6 and Rebulk-offset value is 0.1V
= 54.6-0.1
= 54.5 and charger will start charging again

Is it recommendable to keep the rebulk-offset as low as possible?
My battery chemistry is Lithium ion NMC
Then that is up to you. In your post the battery was down to 50v so clearly the current settings are not great. I am going to ask again though i see equalisation which means a lithium profile was not chosen then edited. Start with that. It removes the equalisation there and a few other things not related and add low temp cut off.
At this point you are really wanting to determine if it is defective or not. So we do need to try to get it to charge.
Not if the bms says no.
The bms control changes things alot here as well. The bms itself may have told the solar not to do anything, which is why i asked about bms control. It it sending a CVL and CCL to the system?
How else is the system programmed? Do you have ESS?
Have no idea on that regarding the CVL and CCL,
No, don’t have ESS.
Is there any fuse will be there in between the battery and charger? For protection purpose inside the charge controller ?
I was thinking there might be any hardware issue happened inside the controller,
Can you please guide me how to resolve and diagnosis it and find out the root cause.
