[Kwant] Does Kwant use Transfer Matrix like Methods or ED?

I tried to read the documentations and everything but got a bit confused. Here's my question and the task I want to complete. I want to simulate a 1d Anderson Model and calculate either Localization Length or Conductance for different system sizes. Now, using normal ED, I can only go up to 5000 system size in 24 hours (100 disorder realizations). Now, I want to calculate quantities like Localization Length/Conductance as a function of system size. At your best estimate, How much system size I'll be able to reach and in what time? And how should I go about coding it? Thanks, Kartikeya
