It isn't LNG, it is CNG. The fill rate is slow, overnight, not like a commercial unit. 1.2 standard cubic meters per hour .....OK but what comes to your house is neither LNG or CNG but natural gas vapor...your home system compresses it to liquid....no?

No. The critical temperature of methane is -82.7°C or -116.9°F. No amount of pressure will liquefy methane above that temperature. At atmospheric pressures, it needs to be cooled to -260°F.
