Can I run an EasySolar-II 3kVA MPPT 250/70 GX, from my current 24v battery banks?

I am currently looking to expand our off grid system as we ran out of power over Christmas last year. Our current system has 4 x 405w panels in 2 strings on a 150/60tr. This is feeding 4 victron 12v telecom 200ah AMG batteries wired in series/parallel to give 24v 400ah 9800wh (4.9kw useable storage) we have a Phoenix Inverter 24v 800.
I intend to add 3kw of extra solar and the ability to monitor the system remotely. The EasySolar-II 3kVA MPPT 250/70 GX looks like a good fit connecting the 150/60tr with a ve direct cable. This unit will minimise the wiring. My question is will my current battery bank handle the extra current draw from the Easysolar -II 3kVA? The current battery setup is wired in 35sqmm.

Thanks

Yes, your battery capacity is ok, but consult your manual for the wire size, 35 will not be enough.

Thank Ludo
50mm sq is what the manual suggests and 300a fuses so I have a bit of rewiring to do.
