How is everything ?

Hi dear.
I have 600 watts ups connected with 300 watts panels. Dry narada battery. Maximum load during peak hours is 4 ceiling fans plus 4 9 watts LED bulbs. I want to get get hybrid solar inverter. I am thinking of 1 KVA axpert or some other good brand inverter. Kindly please suggest me following. ...
Kia 1kva 600 watts panel wala system above load kay liye fit ho ga.
Kia agar main 2 150 AH dry batteries parallel main lagao to ye 600 watt system is ko full charge kar lay ga?
Sath main agar 3 say 4 fans bi chal rahay hoon to.... need suggestions. My priority is maximum use of day lights but don't want long backup in minimum expenditure

Can anyone kindly mention list of companies producing deep cycle batteries in Pakistan and their reviews....

Which brand is better exide, ags, pheonix etc.... Which of them produce deep cycle batteries.... Kindly also rate their performance....

Are deep cycle batteries really better than flooded batteries?

In terms of chemistry there is not much difference between flooded and deep cycle. They are both flooded batteries. Some deep cycle batteries use gel instead of liquid electrolyte, but they all work the same. The only difference is that deep cycle batteries have thicker plates and are better suited for greater depth of discharges, such as in solar or UPS application.

Nobody is producing deep cycle batteries in Pakistan. Local battery manufacturers produce batteries for automotive use and they cannot bear the kind of discharges that we impose on them. Recently Volta/Osaka has started producing tubular batteries. The technology behind tubular is also the same, but the design of the plates is different and they are more tolerant to greater discharges and should perform better than flat plate lead acid batteries. But these are still not deep cycle batteries.

Well said bro.
Actually these batteries made by our local assemblers are for starting purposes to bear a sirge and then keep charging immediately but real deep cycle batteries are made for solar and ups systems and have abilty to discharge as low as 90% DOD.
I am using 4 battery bank of 155ah with my solar system and i DOD these batteries to 50% max for their maximum life.

I want to run paani kee motor on solar panel? How much solar panels and what type of inverter/solar charger will be required?

Also i heard about dc water pumps.... Are they available in karachi?

Guys i want to charge UPS battery via solar panel. Its an exide 225 AH lead acid battery. So i will need an output of about 13-14 volts and at most 20amps which i think are enough. So max wattage needed is 280W. A friend told me to get 350W solar panel due to power losses.

How much will this cost me?

Can i stop the UPS from charging battery and only using it as an inverter?

Yes u can charge your batteries with cc and use your ups just for inverter purposes.
Charge controller might be of Rs 6000 to 10000 not sure though and panels of good quality and 10 years warranty starts from 70 rupees per watt.

Ok. So are there any brand name(s) of the panels and controller which are good? I will go look for them at Hall road.

No brand bro you have to check it for yourself there are too many fake ones that uses big companies name but just check there amperes at full peak sunshine at their shops befor purchase

Bro there are many chinese brands available. And also chinese copies of some famous brands. Market is flooded. I m using 5kv solar system wth orignal german made solar cells which are expensive thn chinese panels.almost double the cost of chinese. If u are buying chinese kindly chk the volts amps and compare it wth the panel specification. Normally it differs from 15- 30%.
