I also want to know about these, also If someone able to quote a rough estimate about the price Sent from my LT22i using Tapatalk

Those are not available in Pakistan

Not so. Available dime a dozen. Called panel meters. Check out the following

http://www.dynamicpowers.com/products.htm

Availability

Lahore - Brandreth Road

Pindi - College Road

Karachi - Lighthouse

However I strongly suggest that those who do not have the requisite background do not buy any digital stuff.

Buy a simple shunt and use your existing digital meter to measure current power etc. using simple maths.

They are available in good price of around 1000rs in Brandreth road Lahore. I checked myself. wiring is very simple too. But still you need some good knowledge of working with electricity.

It is always good to have such a meter.

are there any meter for measuring the total energy generated in KWh, per day and per month.

I haven't seen one locally except the ones WAPDA installs (both mechanical and electronic). PEL manufactures such meters (http://pel.com.pk/?page_id=780) which can certainly be used for this purpose. Another manufacturer is ( http://www.syedbhais.com/electricity_meter_benefits.html ). However I am not conversant with the technical details of these products. In fact if someone could contact them in Lahore to find out detail, it would be beneficial for all of us.

those are for AC systems, can be used after the Inverter/UPS. I'm looking for a cheaper alternative to http://www.morningstarcorp.com/products/tristar-remote-meter-2/

well truly speaking if it is too cheap, it may not be reliable and most of solar stuff do not come under cheap things. always think of reliable long term use. Short term solution usually bring big time loss.

another option is http://www.p3international.com/products/energy-savers.html

By the way the usual electric energy meters are available in market. I bought one for me in i think 700pkr or so. You can try that. I dont think something be cheaper than that... :D

Digital or Analogue ? Nothing better than that... :D

Future conversion with a layman

"Kitnay unit produce kartha hay"

"5 Units kay solar panel hay" ... B)

You can see the meter Tufail is using

It is a simple analogue type machine used by WAPDA. I recommend that this should be installed with all future installations. A small diary should be placed next to it and everybody in the house given instructions that anyone passing by the meter should note the date time and reading on the meter in the diary. This will be a very reliable system of data logging and even the servant in the house can do it. It would certainly be cheaper :P .

Thanks aurangzeb, You are all right this is best data logger and for sure the cheapest one.

yup the most indigenous solution. We had this meter for servant quarter in our hometown.

you have got multiple data loggers

a tristar remote meter http://s1313.photobucket.com/user/tufail_74/media/My%20Solar%20Power%20Setup/DSC_0082_zps32af0e7c.jpg.html?sort=9&o=6

Nizam solar's inverter also logs the data http://s1313.photobucket.com/user/tufail_74/media/My%20Solar%20Power%20Setup/DSC_0042_zps55d4ba75.jpg.html?sort=9&o=3

what is your location ? It looks familiar.

What is the total size of array ? and how is wired up, all in series ? . what was the rate for the solar panel ?

Well I basically installed and left it as I am in KSA now. That time even there was very little sun so could not even test fully but I had a nice day when I got 953 watt out of 1010watt panels.

I have already added 500 watts so the total PV is for 1530 watts now. They are 2 array of 3 panels. They are to the Tristart 45 MPPT. I got from Nizam Energy @ 110pkr/watt (CanadianSolar). I am basically satisfied with the system and them. The guy there is very helping and nice one.

From the current consumption of electricity, it seems I should add another 500watts in next summer as the daily consumption is around 22kWh which used to be around 15kWh when I sized my system.

I am getting around 1200watts there days. I think this is because of high temperature and ti will cross 1500 mark in next couple of month. I checked and found I get average 9.6kWh/day.

I have not connected Inverter to PC as did not had enough time for this. But I have tested my CC with PC and it gave lot of logging info. It was direct RS232 with CC. But I added RM2 for easier use for my family. now they are monitoring or having a look and get good amount of info there.

I live in the Kasur city and I think mine is the first domestic solar setup there.

The setup is designed for a safe and reliable level as there is hell amount of energy present at that place.

Thanks. Excellent post.

which city in KSA ? I also have relatives in KSA.

Yup I'm also thinking about buying panels from Nizam solar, after so many visits, they know me very well :P :P

My consumption is far below your, 12.3 KWh/day (average of the total units consumed in last 12 months including those summer months when I was home alone with AC on for 24x7 )

Which RS232 cable you used ? regular local made or was it some specific model ?

You are also one of those, whose house was visited by WAPDA for "App ka meter nahi guam raha" :lol: :lol:

what is the size of your battery bank ?

Rs 110/watt for such a large array is too high, buy in bulk and they might even lower the rate to Rs 88/watt
