This HA Integration successfully working for most of Must PV1800 models for watching to sensors. BUT this integration have have some limits for user input for another MUST devices (because this HA integration developed only to Must PV1800 3kW).

Describe the solution you'd like

If you change MAXIMUM values x5 for all user inputs - your integration successfully will working with other MUST PV1800 devices to config too (not only for sensor monitoring)

Describe alternatives you've considered

My device: Must 5kw, PV1800

Additional context

Examples (this examples for MY device):

• ID "must_energy_inverter_battery_low_voltage" have maximum value "24", but other invertors have high of "24" - in my case i want set "42"; If you change minimum value to "12" and maximum value to "85" - your integration will working with any PV1800.

• ID "must_energy_battery_stop_charging_voltage" have maximum value "29", but other invertors have high of "29" - in my case i want set "55,8"; If you change minimum value to "12" and maximum value to "110" - your integration will working with any PV1800.

• ID "must_energy_battery_stop_discharging_voltage" have maximum value "29", but other invertors have high of "29" - in my case i want set "45,1"; If you change minimum value to "12" and maximum value to "90" - your integration will working with any PV1800.

• ID "must_energy_float_voltage" have maximum value "29,2", but other invertors have high of "29,2" - in my case i want set "56,1"; If you change minimum value to "12" and maximum value to "110" - your integration will working with any PV1800.

• ID "must_energy_battery_low_voltage" have maximum value "24", but other invertors have high of "24" - in my case i want set "34" If you change minimum value to "12" and maximum value to "70" - your integration will working with any PV1800.

• ID "must_energy_grid_max_charger_current_set" have maximum value "30", but other invertors have high of "30" - in my case i want set "60" If you change minimum value to "10" and maximum value to "120" - your integration will working with any PV1800.
