The Mass Fabricator uses 1,000,000 (1 million) EU to produce 1 UU-Matter, so it would drain all the energy rather quickly. 1 geothermal produces 20 EU/tick, so 20*13=260 EU/tick. A solar panel produces 1 EU/tick, so 6*1=6. You would only have 266 EU going into the MFSU, so the Mass Fabricator would drain it all. And you also have an MFE draining some of the power.
