ACDB / DCDB box — Kaam, Installation aur Cost
ACDB / DCDB box rooftop solar mein kya karta hai, kaise install hota hai, cost kis par depend karta hai, aur quotation mein ise kaise verify karein.
Seedha jawab
ACDB / DCDB box — AC aur DC side ke distribution aur protection box, jinme MCB, SPD aur fuse lagte hain. Yeh system ka electrical safety layer hai — short circuit, overload aur surge ke waqt yeh pehla defence hota hai, aur yahi inverter ko bachata hai.
Isse halke mein lene par kya hota hai
Sasta ya under-rated box lagane par MCB sahi waqt par trip nahi karta, aur fault seedha inverter ya ghar ki wiring tak pahunch jaata hai.
Sabse common galti do hain: AC-rated MCB ko DC side par lagana, aur box ko aisi jagah lagana jahan direct barish ya dhoop padti ho. Doosri galti labelling ki hoti hai — bina label ke box mein baad mein koi bhi technician sahi breaker nahi dhoondh paata, aur emergency mein yahi der bhaari padti hai.
Standards aur specification
Yeh box hi woh jagah hai jahan system ka fault current rukta hai. DC side par DC-rated MCB aur fuse chahiye — AC-rated components DC arc ko bujha nahi paate, aur yahi sabse khatarnak shortcut hai jo kuch installations mein dikhta hai. Enclosure outdoor par kam se kam IP65 hona chahiye, warna monsoon mein andar moisture chala jaata hai aur inverter insulation fault dikhane lagta hai.
Installation kaise hoti hai
DCDB panels aur inverter ke beech lagta hai, ACDB inverter aur ghar ke main board ke beech. Dono weather-rated enclosure mein, pahunch ke andar, aur properly labelled hone chahiye.
- 1Survey ke waqt location aur routing decide hoti hai
- 2Design document mein rating aur specification likhi jaati hai
- 3Material delivery par make/model verify kijiye
- 4ACDB / DCDB box install hota hai, baaki system ke saath coordinate karke
- 5Testing aur measured values ke saath handover report
Verify karne layak cheezein
- Enclosure ka IP rating (outdoor par kam se kam IP65)
- MCB aur SPD ki rating system ki current ke hisaab se
- DC side par DC-rated components (AC MCB DC par use nahi hote)
- Har cable par proper ferrule aur labelling
Cost kis cheez par depend karta hai
ACDB / DCDB box ka koi ek fixed rate nahi hota — woh rating, material quality aur installation scope par badalta hai. Isiliye hum yahan ek number nahi chhapte; upar di gayi checklist hi woh drivers hai jinse aapke quote ka figure bana hai. Website par fixed component price chhapna aapko galat expectation deta hai, kyunki yeh pricing batch aur availability ke saath badalti rehti hai.
- 1Component ka naam, make aur rating quotation par likha ho
- 2Quantity aur (jahan lagu ho) length ya size
- 3Included hai ya extra — saaf likha hua
- 4Warranty period alag se

Aksar poochhe jaane waale sawaal
- Kya ACDB / DCDB box optional hai?
- Nahi. Yeh safety aur compliance ka hissa hai. Iske bina lagaya gaya system inspection mein bhi problem karta hai aur lambe samay mein bhi.
- Do quotes ka farak is component se aa raha hai?
- Ho sakta hai. Bada farak aam taur par capacity, structure aur panel model se aata hai — lekin balance-of-system components ko scope se nikal dena bhi ek common tareeka hai quote ko kam dikhane ka.
- Baad mein add karwa sakte hain?
- Technically haan, lekin baad mein karwana hamesha mehenga aur adhoora hota hai. Installation ke waqt karna hi sahi aur sasta raasta hai.
