The difference between a Solar Charge Controller (SCC) and a Solar Management Unit (SMU) lies in their functionality and purpose:
Solar Charge Controller (SCC) kya hota hai?
- Ye ek device hota hai jo battery ko solar panel se sahi tareeke se charge karta hai.
- Ye battery ko overcharge hone, deep discharge, aur raat me reverse current jaane se bachata hai.
- Do prakar ke hote hain: PWM aur MPPT.
- Ye sirf charging ka kaam karta hai, load ya power management ka nahi.
Solar Management Unit (SMU) kya hota hai?
- SMU ek advanced device hota hai jo solar panel, battery, aur load (appliances) ke beech power ko manage karta hai.
- Ye solar + grid dono se system ko chala sakta hai.
- Jab solar available hota hai to solar ko priority deta hai, aur bijli ke bill ko kam karta hai.
- SMU se aap ek normal inverter system ko solar hybrid system me badal sakte ho.
- Isme automatic switching hoti hai between solar aur electricity (grid).
Mukhy Antar (Main Difference):
| Feature | Solar Charge Controller (SCC) | Solar Management Unit (SMU) |
|---|---|---|
| Sirf battery charge karta hai | ✅ | ✅ |
| Load/Power manage karta hai | ❌ | ✅ |
| Grid/Solar switching | ❌ | ✅ |
| Retrofit (normal inverter me use) | Limited | Easily possible |
| Features | Basic | Advanced |
