Inverter or non inverter tak kesah la. Most important is the 5 stars rating. That will save ur bills alot.

Fridge alone RM8-10 nett for TNB bill.
The inverter saves power bill because fridge motor frequent start stop.

QUOTE(djandrew @ Mar 3 2022, 03:06 PM)
does inverter aircond have more hard time doing service than non inverter aircond? anyone can share some experience? or both the same in terms of maintainance ?
*
Servicing meaning washing, no. Its all the same. Don't get conned.

QUOTE(royalben @ Mar 3 2022, 03:09 PM)
Non-inverter fridge still exist ?
I thought already phase out
*
Still got.. those 800 dollar small fridge.. but usually INV can get 4 or 5 star ST
The NON only score 3 star at best. Sometimes even 2.

QUOTE(Lembu Goreng @ Mar 3 2022, 03:11 PM)
Hmm..

let's say I save RM20/month, about 240/year, need 5 years to recoup the price difference (since inverter is 1k more).

But can save RM20/month meh on electricity bill?
*
Size for size I don't think fridges have a 1k difference. How big is your fridge?

QUOTE(Zot @ Mar 3 2022, 03:13 PM)
even 10 sen also saving.

Inverter one has at least 10 years warranty. Non-inverter usually much shorter as far as I can remember
*
Coz the inverter is kinder to the motor. So the warranty for the motor (compressor) also can stretch longer.

QUOTE(empire @ Mar 3 2022, 03:15 PM)
Inverter parts are DOUBLE PRICE of non inverters. You dont wanna believe, go ahead :-) Dont say I didnt warn you.
*
Only the inverter PCB.

QUOTE(scorgio @ Mar 3 2022, 03:16 PM)
Servicing the same.

Inverter models the copper pipe spec different, so usually installation cost slightly higher.

Next, the key is the Inverter PCB, which is at the outdoor unit. This part warranty only 1 year. If unlucky got fried, then to replace is RM3-500 (last I heard).

Mana ada difference.
NON https://www.daikin.com.my/daikin_products/ftv-a-series/
INV https://www.daikin.com.my/daikin_products/ftku-series/

Its the same 9.52/6.35 and 12.7/6.35mm pipe.
For R32 they all run at high pressure. Pipe thickness 0.61mm is just ticking time bomb if it leak somewhere concealed. Pay more use proper Daikin pancake 0.71mm thick regardless INV or NON.

Hitachi 2 years general warranty. laugh.gif

Just check the electricity consumption advertised then calculate from there.

Type of fridge also affect the electricity consumption. Side by side fridge consume more electricity compare to top freezer of the same size.

Really worth the extra 1k meh?

How many years electricity savings to recoup the 1k?

Most home appliances with price range of 3k-8k have at least lifespan of 5-8 years or longer.
Fridge technology is pretty much at the end stage where there's no industry changing invention coming out anytime soon. Unlike TV you change overtime, but for fridge, you don't change unless its broken.

so you're buying for the long term, its a value buy considering timespan is 5-8 years.
unless you're already planning for upgrade to a jumbo size fridge in 2 years time, then you can always cincai buy a cheaper non inverter ones.

Considering fridge is usually 2nd or 3rd most expensive item that run 24/7, buy lah one Belkin surge protector for the fridge. RM40-50 depending on laz or pee pee sales.

Oh those antiquated old model Hisense SBS vs any RM3k-3.3k branded SBS fridge (Hitachi, Beko) which all come with INV. Some even come with dual inverter.
Having an SBS fridge is for flexing, where got people buy without INV nowadays tongue.gif Want to save money 3k range all come with INV. Just not latest series (that's pure cosmetics only).

NON SBS are very old model stuff. If it cost RM30 extra to run per month due to the 600L and up size, after 33 months you are losing money.

My average bill without AC was 240-270 a month (that's why cannot afford to use AC) all due to an old chest freezer (NON) makan electricity.
Dumped it for INV Hitachi SBS fridge (3800 coz wanted black), white was 3200
Bill nowadays 100-120 only. Steady je.

For price of the fridge alone I ROI under 3 years easily.

You're haunting me or I'm haunting you?

I'm looking for a fridge also. Maybe around the 450 to 500 litre size. I want to push the fridge on those pull out tracks so I can clean behind or access things if needed. This is because I found out my Sharp fridge drain pan corroded and it's been leaking. The last few months I kept thinking it was my washing machine. Maybe that's how they end the life span of the fridge. By having a corroded drain pan. Called Sharp and they don't sell my drain pan. I've patched up the drain pan for now but am looking to switch out the fridge. It is an eventuality.

My electricity bill is pretty high so it must be because of my fridge. I bet it's a non-inverter since it's so old. Do non-inverters eat more electricity as they age and do inverters keep a steady pace?

I agree that 24/7 appliances should be inverter but maybe not for air conds that are on for 8 hours a day. I wonder if ceiling fans really save money with DC motors?

I've been trying to figure out what's drinking electricity. My suspicion is the plasma tv too.

400-500L range..
Mitsu, Hitachi should have something for you in that region. I recommend the Hitachi (443L) R-VG490P8M dual cooling fan and super saving (5* ST). I use this personally, very quiet too.

Non-inverters especially >15 years old fridge tend to suck up more power. Even more when the door rubber seals have minute gaps.
Older fridges tend to lose efficiency after some time.

QUOTE
A 20-year-old refrigerator could use 1,700 kWh of electricity every year, compared with about 450 kWh for a similarly sized new ENERGY STAR model.


I was an inverter sales rep back in the days and almost all factories never say NO to inverters. Inverters wear out after 5-8 years of 24/7 production line usage brows.gif

AC does save at least 20-30% between non and INV models - standard test methodology by ST, whereby NON can never score better than 3* ST (for the better NONs) and inverters 4* to 5* ST.

Ceiling fan not worth spending on DC motors. 41W max vs 68W max. But DC motor easier to control the speeds so thats why you have 9 speed control in DC vs maybe 3-5 speeds in AC motor models.. having more finer "gearing" allows yuragi fx to variate the speed for the wind feels.

You can get a clamp meter and use process of elimination (turn on your appliances one by one) and see what causes high amp draw.

Actually not same. I’m quite clear about AC.

I want to know about fridge, so best to discuss fridge
*
It is the same actually. The air-cond is chilling room by removing heat to outside of the room. In fridge case, the inner side of the fridge is the room and the heat is removed to the outside of the fridge cabin which is into your house unfortunately. smile.gif

If you asked me if it is worth it an extra 1k, I'd say it is not worth due to additional cost for inverter board compare to regular board probably just RM100~200. The compressor still the same compressor but the longer warranty is due to there is no in-rush current to compressor during operation thus it is very unlikely to get the coil burnt. The 1k extra is very much due to inverter is current hype.

As I mentioned before, it depends on how much coldness loss inside your fridge. The more frequent the fridge door is open/close in a day, the more time the compressor works. How much electricity saving related to this factor. If less open/close the fridge door then the difference is saving probably negligible.
