Q5: Can multiple appliances be connected to the 3000VA stabilizer simultaneously?

A: Yes, you can connect multiple appliances to a 3000VA AVR stabilizer as long as the **total power consumption does not exceed 3000 volt-amperes (VA)**. However, it's important to understand the difference between VA (apparent power) and watts (real power), as some devices—especially those with motors or compressors—have a higher starting surge (inrush current) than their rated running power.

To safely determine compatibility:

1. List all appliances: Include TVs, fridges, AC units, microwaves, etc.
2. Check nameplate ratings: Note the VA or wattage (convert watts to VA using power factor ~0.8: VA = Watts ÷ 0.8)
3. Add up total load: Sum the VA values of all devices that may run simultaneously.
4. Account for surge: Motor-driven appliances (e.g., refrigerators, pumps) may require 2–3x their rated VA at startup.

Example: Connecting a 1500VA refrigerator, 800VA air conditioner, and 400VA TV totals 2700VA—within safe limits. But if both the fridge and AC start at the same time, the surge could momentarily exceed 3000VA, potentially tripping the stabilizer or causing voltage drop.

Best Practice: Keep total continuous load below 2400VA (80% of capacity) to accommodate surges and ensure reliable performance. Avoid plugging in high-draw devices like heaters or ovens unless their total load is well within the limit.
