apc 1500 va / 980 watts with 2 X 180 Ah batteries ........ for 3 hours backup time with 600 watts load ...... if no financial constraints then go for dry battery like narada gel 100 ah x 2 ............

[Kaartoos]

Ghani007 go for 2kw grid tie hybrid inverter with 2 x 200ah flooded battery or 2 x 150ah dry type battery

asl. can someone share his experience of using Narada polymer gel battery for UPS. a brand new 155 amp narada vs AGS 195 amp lead acid type battery what are the advantages of it like
1..life in terms of hours or years...currently my AGS gives one hour backup and it 3rd year of purchase. .when it was new then backup was 2 hours.
2. .I heard that it can give 4_6 hours long back up with 4 fans ..as compared to AGS where I get 1-2 hours long backup with 4 fans on

Anyone used OPzV series( Sacred Sun GFMJ-H series) Gel batteries? I see that it has 8000 cycles. Are these available in Pakistan?

You might have bought the fake ones which deplete real fast. Check you inverter once. What have you installed? But my guess is, batteries are losing their life.

Nawan885 what is your load per hour?

Narada 155ah battery storage is max 1800watts means you can run 4 fan for max 5+ hours continuesly . More over you need atleast 32a chg current to cover ghanty pe ghanta loadshedding. 32a current is much more for this narada battery and so it will get damage and wont last longer. But 2 narada that is 300ah

Is it true pantera ?

Yes, you can go to the link I provided along

[Kaartoos]

Hungama007 yes sacred sun gel battery available in Pakistan.

What is the selling price that the govt has set for renewable energy?

The Document says Govt will buy back units produced by you at Rs 12 which is the off-peak hours rate. This happens all over the world so I doubt its robbery. We must be glad about this development and hope it will help our electricity crisis significantly.

Kartoos..
my load per hour is 4 ceiling fans..30 watt. and 30watts lights..this is max load.. usually 3 fans and 2 LED bulb only

Than go for 200ah Narada. 2400w max storage. Your per hour load approx 300 - 400 watts.

Units produced in OFF-PEAK hours (day time) will be adjusted in PEAK hours (night time) within the same month.. Mushkil hay (H)

No. See, extra units produced during the day will be adjusted during the nigh, only off-peak though. Which means, if you produced extra 10 units during the day, they will be used up or netted during night, ie. (From 10pm to 8am). It wont be netted during 7pm-10pm since these are peak hours.
I think it is still bery good because mostly we consume more during 11pm till 8am because thats when our ACs are on.

Thanks for a really simple clarification regarding the adjustment of units sold to wapda.

one thing more if able to show some figure work for all of us;

Cost of New Net-Metering-Meter and other DEMANDS Notices payable to WAPDA, to connect one's Hybrid system with Grid.
