Max. Input Current on Some?

I've noticed that more expensive (higher end?) inverter models like Deye, Sunsync and Goodwe state max. input current limits on their datasheets alongside voltage and power limits. This unfortunately seems to limits their usability to long strings of smaller capacity and older technology panels and unusable with big capacity and especially the newer bifacial panels.

 

"Cheaper" models on the other hand like Luxpower and Growatt only give voltage and power limits along with the max. charging current. Do they also have max. input current limits, what are these/how can one calculate them? Max. array power divide by start-up voltage which is quite high? Are they in fact more practical to use because of this?
