the power consumption also may effect by where u located your a/c compressor... if located at closed area without good air circulation, definitely compressor unit will operate longer than usual... if hot air trapped in closed area, definitely compressor unit suck the hot air back into the unit, the cooling efficiency wont be good enough... if u went to phileo damansara before and have a look at their a/c compartment area, u can see some exhaust ducting installed there, it purposely to lead hot air direct to environment and avoid hot air trapped in the closed area...

it also depend your equipment's technology and wear & tear...
u cant compare with air con which c/w 10 years old technology versus with current air con technology...
for sure even non-inverter air con will save more power too compare to air con which 10 years old technology

hence, inverter will bring more benefits to those appliances which running non-stop or very long usage per day
cant imagine how water heater system can implement inverter into, unless bath more than hours...

anyway, ur XXX can be 100-999

u misunderstood about inverter... doesnt means switch on longer and save more...

example:
non inverter : 8 hours - cost RM100
non inverter : 24 hours - cost RM300
Note: 24 hrs are the 3X of 8hrs

inverter : 8 hours - cost u RM90
inverter : 24 hours - cost u RM240
Note: 24 hrs will be lesser than 3X of 8hrs

if 5000w, the load will burn your house wiring easily which about 20+amp load...
but our standard house wiring & ELCB usually can sustain 15+amp maximum for short tem...

for safety reasons, check equipments' power consumption before use...
recommended not more than 2500watt with standard wiring...

so for those residents planned to use high HP air con, recommended install thicker wiring and ELCB support high amp...
