For those power consumption conscious, the following findings on "inverter-may-not-win-all" is interesting:

1. Pana Inverter MR-BW465X:
Net capacity:365L, Annual consumption: 442KWh
Average consumption per litre : 442KWh/365L = 1.20KWh/L

2. Sharp Energy Saving model SJPT491MBK (SJ-MC36P-BK in Singapore)
Net capacity:368L, Annual consumption: 460KWh
Average consumption per litre : 460KWh/368L = 1.25KWh/L

Saving for the Pana Inverter is only 0.05/1.25 = 4.2% from non-inverter, relative to price difference around RM500 or 33% more.

Still it is up to individual preferences.
