Invertor full load is higher then non-invertor full load.
Mit invertor sys 3 full load can hit > 9 amp.
Mit non-invertor sys 3 ard 8 amp.

can try using an Amp Clamp Meter.

but they're not cheap so better to borrow one if you can.

Hi Innocast,

Thank you for your inputs. Appreciate that you took the time for a long response.

On the cooling capacity, it is what really works that matters. With all this advertised above its working capacity, it feels like being sold a 1.5l car for a 2l car. For ME, the difference is a lot, almost 8000 btu.

My old ME is using 8k, 8k, 12k configuration and I believe BTU was 24k which was the highest 6-8 years ago. It is not cold enough and we have the fan on at the same time. The lower noise also meant that the blower at the indoor units are not as powerful. That was what the installers said when I complained. And with me having to have the fan on as well, any other air conditioner will be quieter...haha....

Hence, looking to get one that will be much higher than the 24k BTU and going for 8k, 12k, 18k. I am not sure if there was any savings when I changed to inverter. My main consideration was that it must be able to cool the room sufficiently and the inverter options had the higher BTUs.

Currently, ME has the highest advertised BTU at 38k, Toshiba at 34k and I think Sanyo at 33k. But in NEA website, ME and Sanyo's at about the same at 30k and Toshiba at 26k.

I also realised that none of these are new models. They have been around for almost a year or longer. After my experience with ME, I am reluctant to buy another ME. I am ok with only using 3 indoor units on a System 4 as long as I can get it cold enough. But no sales person has been able to explain how energy saving that would be or if I can get the full cooling capacity of the condenser.

I've actually called up each of the distributors and honestly, customer service in Singapore sucks. ME and Daikin offered some decent information but Sanyo just informs that they don't have stock and don't even know when they will have it.

Do you have any recommendations for dealers? I have gotten two quotations so far but they seem higher than what is advertised on Cool Serve's website and in one instance just totally ignored what my demands were.

Many thanks!
not to sure if i remember it correctly, but i was told previously by an air-con fella that some of these compressors were clipped (had a current-limiter) when they were sent for testing to get a better energy-ticks-label. So even though the compressor is of a higher capacity, you will not maximize it due to the current-limiter.

anybody can comment on this? whether it is true?

yes, i think so, becos i tried one of the unit in my house, mitsubishi starmex, try to set at 16 degree, it was switched off by its own....

tat one is the total power consumption (kWh) since the last reset.

normal power current is around 7amp..

I think it's 8.5A max at HDB and 11A at private residences. Gain City guys came today and I checked the brochure from Toshiba which shows that it adds up to 26k BTU based on 11A, having 3 indoor units. This is what NEA has for the same model.
