MT50 with Two Controllers

I have two solar systems feeding one 12v lithium 200a/h battery. can I successfully use one MT50 to monitor the battery?
Mainly what I want to do is know the SOC (how much more power is left). I think with one MT50 on one controller I will not know the power coming in from the other controller. so SOC will be unknown. What or how do I monitor SOC?
I have 200 watts 24 volts solar into an Epever charge controller - times two (two identical panel/controller systems feeding into the battery).

And if you want to try something less expensive, there are a surprising number of battery monitors in Amazon and other places:
