Modbus: Reading AC Consumption from grid

Can't seem to find the proper Modbus registers for the values I'm looking for. When I plug my MultiPlus into grid while using AC inverted power, AC devices stay on and AC load drops to zero. Wondering, is there a way to see in Modbus the total energy coming from grid, and then still get a number for the power passed on to "AC Loads" even though that power isn't coming from my system anymore? It seems that the Grid power is showing everything coming in, but with AC Loads set to zero, my calculations are leaving alot of energy "leftover" in the system because no value is subtracting what the AC Loads inside are still using.
