Inverter Turndown Ratios
The inverter systems ramp down/up to match the room load, which is fair enough.
What are the various duty turndown ratios for the various single split inverters?
Daikin, as an example, will ramp down to approx 50% before switching off on low load, as I understand it, though I thought inverters generally would ramp down to about 20% before cutting out on load/temperature.
Any other systems have a better turndown ratio (if that is the correct term for this feature)?

Re: Inverter Turndown Ratios
Digital scroll is not using any inverter. It's just a duty cycle of a solenoid valve.
50% on inverter ramp is quite reasonable. A system which requires reduction for more than 50% of the compressor capacity is grossly oversized.
