Low power mode does not work on Solax #3311
Description
Describe the bug
When enabling low power mode predbat does not send Best rate real to the script, but instead sends battery_rate_max as "{power}"
Expected behaviour
Use "Best rate" as {power}
charge_start_service:
- service: script.solax_remote_control_new_mode_8
power: "{power}"
operation: "Force Charge"
Predbat version
v8.32.14
Environment details
Solax X3 Ultra 30kW, 40kW HV5.1
Standart HAOS
