I check with my contractor,
if the use max 5 aircon, don't need to switch to 3 phase, as long as those aircon not ON at the same time.
Means you can switch on living room aircon first then go upstair switch on the rest of aircon one by one, then is OK.

Modern circuit have made some improvement and some even put in current limiter this reducing the rushin current for startup motor. Even if it go up 6x, is only few seconds.

The current rushing is not even over 1sec. Just 0.5 or less. The main fuse won't blow at all. 

All this possibility, I have conduct experiment before.

Wonder how can the house owner switch on the same time? Even after power trip, the A/C auto on is also random timed, that was one of the reason the random switch on time was design.

Added on November 19, 2012, 1:47 pmAh well, maybe we have many well to do home owner, target to have lots of high HP a/c switch on, and few hundreds lights switch on daily. Ok to pay for TNB.

Maybe I should buy TNB share already

Is not sound, is actually not worth it if your appliance are not power hunger.

The proper way is to check your whole house electrical applicance wattage using. Than total up the wattage. Some not using everydayo, minus out.

Weikee already state that as long as it doesn't over 14,400watt total usage, you don't neeed change to 3phase.

If consistan using 14,400 or maybe at 90% 13,000 watt than is good to change to 3 phase, but only just short spike don't need.

BTW, if using 14,400 watt, that is paying RM 5+ per hours,  if use for 3 hours perday that is paying RM 450.00 for just this 3 hours x 30 days. Add with other daily usage, minimal house hold electrical bills will go up to RM 500++

Not sure on this, but I guess it's Single Phase.
Cos mine is 3 Phase, I have 3 black box thingy, instead of 1

Noted. Thanks. I am going for 3Phase then. Easier and feel Safer on the overloading. 
Banting Area, Still having 3Phase Promotion? will go over and apply by year end.

Using water heater 24/7? No right? Then no need. You only need to consider 3 phase if you are using 3 air conds all the time.
But 3 phase wiring are quite expensive to do. The good thing is, your wire can last longer since they are not stressed.

Yup, that's right.
Only some mad people will on every thing at the same time.

Anyway, every January I'm getting some refund, as far as I heard, it is the deposit I put in last time(rm800).

Yup, it is stated as "pelbagai"
If charge extra, I make noise, if get back money, keep quiet.

Let's wait for another 4 months and see.
But you need to fullfill certain condition to get this, if not mistaken it will be prompt payment(now in order to get rm50 CB, every month will pay extra), use above certain limit(so in some sense you need to waste)

Getting Seda? Want to sell back to TNB?
What is the goal you want? If invest to gain money, then you may think again.
I have 2 friends installed this, 1 installed long time ago and his ROI are 7%, another is lower at 3-4%
The rate is getting lower and lower now. So for cooling your house, then go ahead, if trying to make money from it, sorry, wrong tools.
After installing this solar panels(on the right direction to harvest sunlight), you will have a cooler house, your air cond cost also can come down.

Yes, that's right. Or can say you got additional layer of roof.

So we need to weight the solar panel installation, what do we want in the end.
Still, why we need to have quota for this? In Malaysia, we are blessed with sunlight > 180 days. Even in the rainy days, we are still getting some sunlight.
Like European countries, they are ditching fired power generation and encouraging people to use green power to generate power.
