Hi i have 24 x 80 watt solar panels wired in series to 1080 amp hour lead acid batterys through victron mppt 150/60 tr smart reg I want to run 2 mppt 250/70 tr ve can reg in parallel from a different set of 415 x 16 panels in series and parallel to same set of batterys and can i get the 3 mppt regulators to communicate to each other Thanks in advance Ted
You can do that via VE.Smart Networking. One of the three charge regulators will become the master and will guide the other two regulators in the charging phase. Before creating the network just set the charging parameters (according to your need) in the three charger. For more details

Please check panel strings to the MPPTs with the Victron online calculator. Looks like you're going to kill the MPPTs with over voltage.
