🔍 Solar Inverter Me Error Codes Aana Kyu Shuru Hota Hai?

Solar inverter smart technology use karta hai jo:

✔ Voltage monitor karta hai
✔ Battery charge protect karta hai
✔ Solar panel output track karta hai
✔ Grid connection ko verify karta hai

Agar koi bhi parameter safe range se bahar jaye → error code.

⚠ Most Common Solar Inverter Error Codes & Solutions

Neeche sabse common error codes ka simple explanation + easy solutions diye gaye hain.

1️⃣ Error Code: PV Over Voltage / PV High Voltage

Meaning:

Solar panel ka voltage inverter ki max capacity se zyada ho gaya.

Causes:

• Extra panels series me connect
• Wrong wiring
• Oversized solar array
• Cold weather me panel voltage spike

Solution:

✔ Solar panel Voc rating check karein
✔ Zyada panels ko series se remove karein
✔ Wiring diagram verify karein
✔ MPPT settings reset karein

2️⃣ Error Code: PV Low Voltage / PV Under Voltage

Meaning:

Solar panel ka voltage minimum limit se kam hai, inverter start nahi karega.

Causes:

• Cloudy weather
• Loose solar connector
• Panel me dust/shading
• Wrong panel configuration

Solution:

✔ MC4 connectors tight karein
✔ Wiring connection recheck karein
✔ Panel clean karein
✔ Series/paralle configuration correct karein

3️⃣ Error Code: Grid Fail / AC Input Fail

Meaning:

Inverter ko grid ka input (AC) nahi mil raha.

Causes:

• Grid outage
• MCB off
• Loose wire
• AC cable damaged

Solution:

✔ Grid supply check karein
✔ MCB on karein
✔ AC input wire tighten karein
✔ Fuse check karein

4️⃣ Error Code: Battery Low / Battery Under Voltage

Meaning:

Battery safe limit se niche discharge ho chuki hai.

Causes:

• Poor battery health
• Solar charging low
• Extra load
• Faulty battery wire

Solution:

✔ Battery ko fully charge karein
✔ Load kam karein
✔ Battery water level check karein
✔ Damaged battery wire replace karein

5️⃣ Error Code: Battery High Voltage / Over Voltage

Meaning:

Battery excessively charge ho rahi hai.

Causes:

• Charge controller issue
• Panel over wattage
• Faulty MPPT/PWM

Solution:

✔ Charge controller settings reset karein
✔ Battery terminals saaf karein
✔ MPPT/PWM check karein
✔ Oversized panel ko balance karein

6️⃣ Error Code: Overload / Load High

Meaning:

Inverter se zyada load consumption ho raha hai.

Causes:

• High power devices (AC, heater)
• Extra appliances
• Loose output wire

Solution:

✔ Load reduce karein
✔ Only suitable devices use karein
✔ Wiring heat check karein

7️⃣ Error Code: Short Circuit / Output Short

Meaning:

Inverter output side me short circuit detect hua.

Causes:

• Faulty plug
• Damaged wiring
• High-pressure device

Solution:

✔ Sab plugs inspect karein
✔ Shorted wiring replace karein
✔ Load recheck karein

8️⃣ Error Code: Isolation Resistance Fault

Meaning:

Panel wiring ya AC output me leakage current detect hua.

Causes:

• Wet wiring
• Insulation damage
• Faulty earthing

Solution:

✔ Earthing check karein
✔ Wet connectors dry karein
✔ Faulty wire change karein

9️⃣ Error Code: Temperature High / Over Temperature

Meaning:

Inverter ka internal temperature safe limit se upar hai.

Causes:

• Fan jam
• Poor air ventilation
• Heat waves
• High load

Solution:

✔ Inverter ko airy space me install karein
✔ Cooling fan clean karein
✔ Overload reduce karein

🔟 Error Code: Communication Lost / Com Error

Meaning:

Inverter aur monitoring device (WiFi dongle, app) ka connection lost ho gaya.

Causes:

• Cable loose
• WiFi failure
• App not working

Solution:

✔ WiFi dongle replug karein
✔ App restart karein
✔ RS485/USB cable reinsert karein

🔧 Additional Error Codes List (Quick Table)

🛠 Jab Ye Errors Technician Required Hote Hain

Aapko professional technician bulana चाहिए agar:

✔ Burning smell aaye
✔ Display completely dead ho
✔ Wiring heat ho rahi ho
✔ Repeated error fix nahi ho raha
✔ Grid synchronization problem ho

💡 Conclusion

Solar inverter errors normal hote hain aur inka solution easy bhi hota hai.
Agar daily basis par sahi maintenance ho, wiring proper ho, aur system clean rahe, to inverter long-lasting performance deta hai.
