Fix for #18503

This PR adds the 3rd MPPT of the Solax X3-Ultra Hybrid Inverters. Now evcc shows the "right" values for my X3-Ultra-25K. I still think, reading the MPPTs is the wrong way, because there are other registers which show the actual power which is send to the house grid, but I have to-do some tests first.
I don't know if we have to differentiate between inverters with different numbers of MPPTs? Or will the register of the 3rd MPPT just be ignored if it's not there on other Solax inverters.
