Fox ESS H3 Series (Three-Phase Hybrid Inverter) – Mukammal Tafseel
Fox ESS H3 series ek advanced Three-Phase Hybrid Inverter hai jo gharon aur chotay karobaron (commercial use) ke liye design kiya gaya hai. Yeh inverter sirf solar panels se bijli nahi banata, balkay batteries ko charge karne aur extra bijli grid ko dene (Net Metering) ki salahiyat bhi rakhta hai.
Inverter ki Khaas Khususiyaat (Key Features):
- Dual MPPT Design: Is mein do alag MPPT (Maximum Power Point Tracking) trackers hotay hain. Jaisa ke aapne dekha, MPPT1 aur MPPT2 dono mil kar taqreeban 10kW tak ki behtareen production dete hain.
- High Voltage Battery Support: Yeh inverter high-voltage lithium batteries (maslan Fox ESS ya Inverex PowerWall) ke saath kaam karta hai. Is mein communication ke liye Master/Slave settings hoti hain (Switch 1 ON, Switch 2 OFF).
- IP65 Protection: Yeh inverter dhool aur halki baarish se mehfooz hai (Dust & Waterproof), jo Karachi ke mausam ke liye behtareen hai.
- Smart Monitoring: Is mein built-in WiFi hota hai jis se aap mobile app par live generation aur load dekh sakte hain.
- Safety Protections: Is mein Residual Current Monitoring (Iso/Isolation check) ka system hota hai. Agar system mein 39V ya 88V jaisa leakage current aaye, to yeh "Res Cur Fault" de kar system ko jalne se bachata hai.
Inverter ke Technical Points (Blog ke liye):
- Efficiency: Iski efficiency taqreeban 98% tak hoti hai, yani solar energy ka zaya bohat kam hota hai.
- Wide Voltage Range: Iska MPPT voltage range kaafi wasee (wide) hai, jo taqreeban 160V se 950V tak jata hai. Aapne jo 11-11 panels ki strings lagayi hain (430V-440V), woh is range mein bilkul perfect fit aati hain.
- EPS Function: Bijli janay ki surat mein yeh Emergency Power Supply (EPS) mode par shift ho jata hai taake aapka load chalta rahe.
Fox ESS H3 jaise high-end inverter ke liye proper earthing bohat zaroori hai. Agar earthing kamzor ho (maslan Neutral-to-Earth 5V se zyada ho), to system error deta hai aur motherboard kharab home ka khatra hota hai.
Fox ESS H3 series jaise advanced hybrid inverters ke saath net metering ka process kaafi behtar ho jata hai kyunke ye system grid-tie aur off-grid dono khususiyaat rakhta hai.
Net metering ke liye zaroori maloomat aur process ki details niche di gayi hain:
Net Metering Kya Hai aur Iske Faide?
- Bijli ki Farokht: Din ke waqt jab aapke panels (maslan 10kW system) ghar ki zaroorat se zyada bijli banate hain, to woh grid (KE/WAPDA) ko chali jati hai.
- Bill mein Kami: Raat ke waqt jo bijli aap grid se lete hain, woh din ki bheji gayi bijli se minus (offset) ho jati hai.
- Fox ESS ki Salahiyat: Fox ESS H3 inverter net metering ke liye bilkul tayyar (compliant) hota hai aur is mein export control ki settings maujood hoti hain.
