Inverter Battery Backup Calculator — Light Jaane Par Kitne Ghante Chalega
Battery par likha hota hai 150Ah, aur dukaandaar kehta hai "6-7 ghante aaraam se". Par ghar me pankhe, light aur TV ek saath chalein to backup kitna milega, ye ek seedhe hisaab se nikalta hai.
Neeche apni battery aur ghar ka load daaliye. Backup ke ghante aur sahi inverter ka size dono dikh jaayenge.
Hisaab ka tarika — Ah ko watt-hour me badliye
Battery ka Ah akela kuch nahi batata. Use volt se guna karne par hi asli urja (watt-hour) milti hai.
Ab ise load se bhaag dijiye. 200 watt ke load par 1,224 ÷ 200 = 6.1 ghante. Load 400 watt ho to 3 ghante. Backup seedha load ke ulte anupaat me ghatta hai.
Ghar ke saamaan kitna watt lete hain
| Saamaan | Lagbhag watt |
|---|---|
| Purana ceiling pankha | 70 se 80 W |
| BLDC pankha | 28 se 35 W |
| LED bulb | 9 se 12 W |
| LED tube light | 18 se 22 W |
| LED TV (32-43 inch) | 50 se 100 W |
| Wi-Fi router | 10 se 15 W |
| Mobile charger | 5 se 20 W |
| Fridge (chalte waqt) | 100 se 250 W |
Misaal: 3 purane pankhe (225 W) + 4 LED bulb (40 W) + router (12 W) = lagbhag 277 W. 150Ah battery par lagbhag 4.4 ghante.

Kitne VA ka inverter chahiye
Inverter ka size VA me likha hota hai, load watt me. Ghar ke saamaan ka power factor lagbhag 0.8 maana jaata hai.
| Ghar ka load | Inverter (lagbhag) | Aam battery set-up |
|---|---|---|
| 300 W tak | 500-700 VA | 1 battery, 12V |
| 300 se 650 W | 900-1100 VA | 1 battery, 12V |
| 650 se 1200 W | 1500-2000 VA | 2 battery, 24V |
Inverter ka VA backup nahi badhata. Backup sirf battery ki urja aur load se tay hota hai. Bada inverter sirf zyada saamaan ek saath chalane deta hai.
Tubular, lead-acid ya lithium — kya farak
| Baat | Tubular / lead-acid | Lithium (LiFePO4) |
|---|---|---|
| Kaam aane wala hissa | Lagbhag 80% | Lagbhag 90% |
| Paani daalna | Haan, kuch mahine me | Nahi |
| Umar | Aam taur par 4-6 saal | Aam taur par zyada |
| Keemat | Kam | Kaafi zyada |
Jahan bijli roz lambi jaati hai, wahan lithium ka zyada istemaal hone wala hissa aur lambi umar uski keemat ko kuch had tak sahi thehrate hain. Kabhi-kabhaar ki katauti ke liye tubular battery aam taur par kaafi hai.
Backup kam kyun milta hai — 5 aam wajah
- Battery purani ho gayi — 3-4 saal baad urja dheere-dheere ghat jaati hai.
- Paani ka star kam — lead-acid battery me plate sookh kar kharab hoti hain.
- Garam jagah — battery ko hawadaar, chhaya wali jagah rakhiye.
- Motor wala saamaan — fridge, pump ya mixer shuru hote waqt kai guna bijli khinchte hain.
- Battery poori charge nahi hui — baar-baar katauti me battery aadhi charge par hi chalti rehti hai.

Aksar pooche jaane wale sawaal
150Ah battery kitne ghante chalti hai?
12V ki 150Ah battery me lagbhag 1.2 kWh kaam aati hai. 200 watt load par lagbhag 6 ghante, 100 watt par lagbhag 12 ghante aur 400 watt par lagbhag 3 ghante.
Inverter backup ka formula kya hai?
Backup (ghante) = Ah × volt × battery ki ginti × 0.8 × 0.85 ÷ load watt. Lithium battery me 0.8 ki jagah lagbhag 0.9 lete hain.
Kitne VA ka inverter lena chahiye?
Load (watt) ko 0.8 se bhaag dein, phir thodi gunjaish jod dein. 600 watt load ke liye 900-1000 VA ka inverter theek rehta hai.
Bada inverter lene se backup badhta hai?
Nahi. Backup battery ki urja aur load se tay hota hai. Bada inverter sirf zyada saamaan ek saath chalane deta hai.
BLDC pankhe se backup kitna badhta hai?
BLDC pankha 28-35 watt leta hai jabki purana 70-80 watt. Teen pankhe badalne se backup lagbhag dugna ho sakta hai.
