Inverter Type AC in Pakistan (Inverter/Non Inverter Dedicated Discussion)

[MuhammadMusa]

Nowadays the temp has cooled down hence you are getting a decent solar production. This would not have been possible about 2 weeks ago. the efficiency can improve to full 1500 watts but i have seen panels producing close to 105 % of their capacity even hence you can go to 1550 even.

It is decreasing day by day instead of improving now not more then 1.06 kw max that too around 1 pm

makes sense...its hot outside... remember the panels will perform best between 20 and 30/35 degrees. The moment you go above 38 to 40 you will definitely start loosing power. On a rough basis it is said that a single degree rise will lead to 80 watts decrease.
You will get similar results till mid september. the best performance is received from september to mid november and from Mid feb to mid April.
An inverter with PV support above the designed output is thus preferred and thus my insistence that if you have a load of 2500 to 2600 watts then the best inverter is Infini plus which has a PV support of 4500 watts.

Thanks whiteangel.
I am dead tired paying ke bills - i have one 1.5 tons ac plus usual house load and with approx. 3 hours run, my bill comes close to 20,000/- per month. With regret i have only one single phase meter for the whole double story house and i have spent years trying to get another meter installed to make separate for each floor but ke says that they have 'one meter on one house' policy ????? This is now becoming too difficult for me to run the house with such huge bills?? Any ideas that might help me out are requested.

[Asifijaz]

its better if we continue our discussion under solar panel system guide... before mods tell us to do so:P:D
or you can PM me

may be i need to open a new thread "KE ke meherbanian"

pay them some money, we recently install two meters now we have 3 meters in two kinal single story home. n soon we ll install 4th meter, 25 se 30 k ka bill 8-9 hazar ata hai, 4rth lagwany k bad 5-6 hazar rah jay ga.

Even I am using 3 meters in a one kanal house there is no restrictions like one meter per house

Brother - there is strict policy application in this matter at Karachi electric!! I am so fedup in this matter that now think it is near to impossible therefore thinking of some alternate energy source to shift my load partly on it.

sir - it is unfortunately in karachi..

@asifijaz You are right but when temperature falls we have mostly cloudy days here is lahore : ( I think I should plan to replace my infini with infini plus

Just checked the current with an amp meter LG 2 tonn split latest model bought last year in October consuming 14 amps.

yes..Musa.. that is why i excluded half of nov, dec, jan and part of feb as well... Infini plus is the cheapest solution with a practical design.. if only they had a 5kw unit or if we could sync two models together... :S

[MuhammadMusa]

But I have already installed an infini : (

Musa Bro its going to be a long shot... but try working out the economics on getting ur inverter replaced vs getting a good quality lets say 40 amp (or 20+20amps) external charge controller and installing it on ur Battery bank... change the settings on ur infini to serve installed load and deficit met via Batteries... For this to work you need Deep cycle batteries, good quality external charge controller and technical details of the batteries and charge controller.
spend some time on this bro and compare the 2 options i.e. replacing infini vs external application. let the logic prevail afterwards

How come so much difference in bill with more meters ? I understand electricity units get costlier with increased consumption. Is it because of that formula bill is less with more meters or some other reason ? Thanks

Why do you want to install Infini plus, you only need Infini plus if you are planning on installing more than 3200W panels. Both models are identical the only difference is that Infini Plus supports up to 4500W panels.

The only reason you would need an Infini Plus is if you plan to get run the Infini close to its maximum load of 3000W, which is not really recommended by the way.

[MuhammadMusa]

Just on Asifijaz's advice I thought infini plus is better

White angel.. Bro you are wrong here...I have a Infi plus installed at Lahore Cant with maximum PV support of 4500 watts. the maximum current that we have received in the last month was 2850 watts. which itself is less than the full load on Infini Plus. We have 2470 watts load on infi including 2 energy savers per room + fan + LED and a 1.5 ton Inverter AC by Acson...
Remember panels are designed for optimum temperature... which is between 25 +/- 5 degrees. except for 4 months temperature is always above or below this optimum range...
In my earlier posts i have myself said so many times that chinese brands are not like SMA or Schneider which can be use on full capacity... but you should be able to use whatever reasonable load that you have put on a chinese inverter... and that is exactly where infini plus comes in

[whiteangel]

What you are saying is exactly what I was trying to explain to him. He doesn't have the PV power right now to justify the switch to Infini Plus. But if he wants to upgrade in the near future then Infini plus might be worth it.

What I don't like about the Infini is that you cannot pair two inverters together and use them as one. I hope their future models add this feature. The Schneider XW series is notable in this respect. You can pair as many XW inverters as you want up to a maximum of 36000W

[MuhammadMusa]

@whiteangel I am upgrading to full capacity in near future thats y I am thinking about infini plus
