Yeh sawal itna common hai ke iska ek seedha jawab nahi ho sakta, kyun ke battery ka size aapke panel ki tadaad pe nahi, balke raat ko aap kya chalana chahte hain, is pe depend karta hai. Panel din mein bijli banate hain. Battery ka kaam sirf itna hai ke wo din ki bachi hui bijli sambhal kar raat ko istemal ke liye rakhe.
Ek quick andaza: sirf lights, fans aur fridge ke liye 5kWh kaafi hai. Ek AC bhi kuch ghante raat ko chalana ho tou 10kWh chahiye. Poori raat AC aur poora ghar chalana ho tou 15kWh se 20kWh tak jana parega.
Neeche poora tareeqa hai apna asal number nikalne ka. Lithium rate hafte mein kai dafa change hota hai, is liye aaj ka confirmed rate WhatsApp pe 03192070022 se maloom karein.
Battery zyada zaroori kyun ho gayi hai
9 February 2026 se NEPRA ne net metering khatam kar ke net billing shuru ki. Ab grid ko bechi gayi bijli sirf Rs 8 se Rs 11 per unit milti hai, jabke grid se khareedi gayi bijli Rs 40 se Rs 60 per unit tak parti hai.
Iska matlab: jo bijli aap din mein bana kar khud use kar lein, wo bijli jo aap raat ko battery se nikal kar use karte hain, uski value ab grid ko bechne se kahin zyada hai. Yehi wajah hai ke battery pehle luxury item thi, ab zyada tar hybrid systems ka zaroori hissa ban gayi hai.
Pehla tareeqa: raat ka load list banayein
Yeh sab se sahi tareeqa hai. Sooraj dhalne ke baad aap ghar mein kya kya chalate hain, wo likh lein.
| Appliance | Typical load | 6 ghante ka hisaab |
|---|---|---|
| 1.5 ton inverter AC | 1,000 – 1,400W | 6.0 – 8.4 kWh |
| Refrigerator | 150 – 250W average | 0.9 – 1.5 kWh |
| Deep freezer | 200 – 300W average | 1.2 – 1.8 kWh |
| 4 ceiling fans | 240W total | 1.4 kWh |
| Poore ghar ki LED lights | 100 – 200W | 0.6 – 1.2 kWh |
| TV aur electronics | 150W | 0.9 kWh |
| Water pump | 750W, thori der | 0.4 – 0.8 kWh |
Sab ko jama karein, phir usable depth of discharge (aam tor par 90 percent) se divide kar dein. Agar aap ki asal zaroorat 9kWh ban rahi hai, tou aap ko roughly 10kWh nameplate battery chahiye hogi.
Size ke hisaab se rough guide
| Ghar ki zaroorat | Battery size |
|---|---|
| Sirf lights, fans, fridge | 5 kWh |
| Upar wala + ek AC kuch ghante | 10 kWh |
| Do AC aur poora load raat bhar | 15 – 20 kWh |
| Chota commercial jo raat ko chalta ho | 20 kWh se upar |
AC ka hisaab sab se zyada battery size badalta hai. Ek 1 ton inverter AC ke liye kitni bijli chahiye hoti hai, iska poora din bhar ka hisaab hamari solar panels for 1 ton AC guide mein hai, jo raat ke hisaab se battery calculate karne mein bhi kaam aata hai.
Rated capacity aur asal usable capacity mein farq
Ek 10kWh battery aap ko 10kWh nahi deti. Depth of discharge, inverter conversion losses, aur BMS reserve, sab mil kar kuch hissa kaat lete hain.
Asal mein, ek 10kWh LiFePO4 battery se roughly 8.5 se 9kWh tak hi milta hai. Jab bhi koi seller aap ko capacity bataye, poochein ke yeh rated number hai ya usable number, kyun ke dono mein farq quotation compare karte waqt bara farq dal deta hai.
Lithium vs purani tubular battery
Zyada tar Pakistani gharon mein pehle se tubular lead-acid battery lagi hoti hai, is liye comparison samajhna zaroori hai.
| Lithium (LiFePO4) | Tubular lead-acid | |
|---|---|---|
| Cycle life | 6,000 – 8,000 cycles | 800 – 1,200 cycles |
| Asal life | 12 – 18 saal | 3 – 4 saal |
| Usable depth of discharge | 90 – 95% | 50 – 60% |
| Maintenance | Koi nahi | Pani dalna, terminal saaf karna |
| Charging speed | Tez | Sust |
Depth of discharge wali line sab se zyada matter karti hai. Ek 10kWh lithium bank se roughly 9kWh mil jati hai, jabke wahi rating ki lead-acid bank se sirf roughly 5kWh, kyun ke lead-acid ko 50 percent se zyada discharge karna uski life kam kar deta hai. Is liye dono ka sirf sticker size dekh kar comparison karna ghalat hoga, asal usable energy dekhni chahiye.
Lead-acid battery teen se char baar khareedni parti hai lithium ki ek life ke doran, aur har baar labour aur disposal ka kharcha alag se hota hai. Zyada tar cases mein lithium end mein sasti sabit hoti hai, upfront mehngi hone ke bawajood.
Battery ki qeemat kis cheez se banti hai
Sirf capacity (kWh) hi qeemat decide nahi karti. Chaar cheezein rate ko upar neeche karti hain.
Cell grade. Fresh, matched cells mehenga parti hain B-grade ya salvaged EV cells ke muqable, jo sasti tou hain lekin shuru ke kuch mahino ke baad unevenly degrade karti hain.
BMS ki quality. Battery management system hi decide karta hai ke battery 15 saal chalegi ya 3 saal. Kamzor BMS wali sasti battery asal mein bargain nahi, countdown hoti hai.
Voltage platform. Zyada tar residential systems 48V low-voltage stackable modules use karte hain, jo aam tor par sasty hote hain aur zyada inverters ke sath compatible hote hain. High-voltage platforms bare commercial loads ke liye behtar hain, lekin mehenge bhi.
Brand aur warranty backing. Established brand jinka Pakistan mein service network hai, unband ya local packs se mehenge hote hain, lekin warranty claim honi ki soorat mein yehi farq matter karta hai.
AC raat bhar chalana sab se mehenga faisla hai
Bohat se log AC poori raat chalana chahte hain aur us hisaab se bari battery le lete hain, phir bill dekh kar hairan ho jate hain. Ek practical tareeqa yeh hai ke AC raat 12 baje tak chalayein, phir fans pe switch kar dein. Is se battery ki zaroorat aksar aadhi ho jati hai, aur upfront kharcha bhi kaafi kam ho jata hai.
Agar aap poori raat AC chalana zaroori samajhte hain, tou battery size seedha dogna ho sakta hai, is liye yeh faisla soch samajh kar lein.
Inverter ke sath compatibility zaroori hai
Battery aur inverter aapas mein baat karte hain, CAN bus ya RS-485 ke zariye. Battery ka BMS inverter ko batata hai ke charge state kya hai aur kitna current chahiye. Agar dono ka protocol match nahi karta, system sahi kaam nahi karega.
Kharidne se pehle confirm karein ke aap ki battery aap ke inverter ke supported list mein hai, sirf brand nahi, exact model number bhi. Inverter select karne ka poora tareeqa hamari hybrid inverter price in Pakistan guide mein hai.
Ek zaroori rule: kabhi bhi ek hi bank mein do mukhtalif brand ya capacity ki battery mix na karein. Alag BMS aur charge rate poori bank ko nuksan pohancha sakte hain.
LiFePO4 hi kyun
Lithium mein bhi mukhtalif chemistry hoti hai, lekin solar storage ke liye LiFePO4 (lithium iron phosphate) hi standard hai. Yeh garmi mein zyada stable hai, roz cycle karne ke liye bani hai, aur Pakistan ke mausam mein sab se zyada reliable sabit hoti hai. Poora comparison lead-acid ke sath, aur brands ka guide (Pylontech, Dyness, BYD), hamari lithium battery price in Pakistan page pe hai.
Garmi battery ki life kam kar deti hai
Pakistan mein battery ko sahi jagah rakhna utna hi zaroori hai jitna sahi size lena. Agar battery kisi band, bina hawa wale kamre mein lagi ho jahan temperature 40°C se upar chala jaye, uski life tezi se kam ho jati hai.
Battery ko shaded, hawadar jagah pe lagwayein, seedhi dhoop se door. Yeh chhoti si baat hai lekin battery ki 12 se 18 saal ki life ko genuinely affect karti hai.
Modular systems: baad mein add kar sakte hain
Zyada tar aaj kal ki lithium batteries modular hoti hain, matlab aap ek module se shuru kar ke baad mein aur add kar sakte hain, jab budget allow kare. Sirf yeh yaad rahe ke wahi brand aur model family use karein, mix na karein.
Yeh un logon ke liye acha option hai jo abhi poori battery ka kharcha nahi utha sakte, lekin future mein barhana chahte hain. Shuru mein thora chota system le kar, zaroorat ke hisaab se barhate rahein.
Poore system ka kharcha
Battery sirf ek hissa hai. Panel, inverter, structure aur labour ka poora hisaab hamari 10kW solar system price in Pakistan guide mein hai, aur panel ke current rates hamari solar panel price in Pakistan today guide mein dekhe ja sakte hain.
Battery ka rate is guide mein jaan boojh kar nahi diya gaya, kyun ke lithium cell cost aur dollar rate hafte mein kai dafa move karte hain. Koi bhi print kiya hua number kuch hafton mein purana ho jayega. Aaj ka confirmed battery rate jaanne ke liye WhatsApp karein 03192070022 par.
Kharidne se pehle yeh zaroor poochein
Model number aur capacity likhwa kar lein, aur delivery pe nameplate check karein. Cell grade aur origin poochein. Cycle rating aur warranty poochein, khaas kar capacity retention kitne saal tak guarantee hai. Warranty ko local kaun honour karega, yeh bhi confirm karein. Aur inverter ke sath compatibility likhwa kar lein, sirf verbal confirmation kaafi nahi.
