X1 Vast Solax Inverter data for Home Assistant

I have the Solax X1 Vast 10k inverter with 13 batteries set up as a stack of 7 and a stack of 6. I am using Home Assistant to try and monitor and control the system, the usual method is by using the add in “Solax Inverter Modbus” which appears to work for lots of Solax inverters but the X1 Vast is missing from the list. I get some data for battery stack 1 but not stack 2 and some of the values are wrong : grid voltage 0v and some data is missing battery stack 2 A, V, Watts and solar Power.
