By PSI Editorial · 5 min · Updated August 21, 2026
💡 Quick Summary & Key Takeaways
- Number of 580W Panels: 6 to 8 Panels
- Total Solar Capacity: 3.5kW – 4.6kW DC
- Recommended Inverter: 5kW / 6kW Pure Sine Wave Hybrid Inverter
- Supported House Load: 1x 2-Ton AC + Refrigerator + Fans + Lights
1. Power Consumption Profile of a 2-Ton Inverter AC
A 2-Ton (24,000 BTU) DC inverter AC is typically installed in large master bedrooms, drawing rooms, or commercial halls.
- Peak Compressor Pull: 2,200W – 2,700W during startup.
- Eco Steady State: 950W – 1,350W once the room is chilled.
2. Sizing Calculation with 580W Tier-1 Panels
Accounting for summer thermal derating (panels producing ~80% of rated capacity on 45°C summer days):
- 6x 580W Panels (3.48kW rated): Delivers ~2,750W real output — sufficient for 2-ton AC and 2 fans.
- 8x 580W Panels (4.64kW rated): Delivers ~3,700W real output — powers 2-ton AC, refrigerator, 5 DC inverter fans, and household lighting with surplus to spare.
3. Operating Recommendations
To optimize energy use:
- Maintain thermostat at 26°C.
- Ensure outdoor condenser unit is placed in a shaded, well-ventilated spot on the roof.
- Wash AC filters bi-weekly to prevent compressor strain.
Frequently Asked Questions
How many 580W solar panels are needed for a 2-ton inverter AC?
You need 6 to 8 panels of 580W (approx 3.5kW to 4.6kW DC capacity) to run a 2-ton inverter AC smoothly throughout peak daytime hours.
What is the power consumption of a 2-ton inverter AC?
A 2-ton inverter AC consumes 2,000W to 2,600W during initial compressor startup, and drops to 900W–1,400W in steady-state maintenance mode at 26°C.
What size inverter is needed for a 2-ton AC?
A minimum 4.2kW to 6kW hybrid or on-grid inverter is recommended to easily handle startup surge and other simultaneous household loads.
