A 3 ton AC is common in large drawing rooms, offices, and shops. To run it comfortably with load shedding backup, you need 10–14 solar panels and an 8kW–10kW inverter. Here is the complete sizing and pricing guide for Pakistan 2026.
A 3 ton inverter AC draws 2,200–2,700 watts when cooling at full load. Running in a Pakistani office or large room for 8–10 hours, it consumes 20–27 kWh per day from the AC alone. Combined with office equipment or home loads, total daily consumption reaches 25–35 kWh.
| Load Item | Running Power | Hours/Day | Daily Units |
|---|---|---|---|
| 3 Ton Inverter AC Main Load | 2,200–2,700W | 8–10 hrs | 18–27 kWh |
| Computers / Office Equipment | 500–1,000W | 8 hrs | 4–8 kWh |
| LED Lights (10 rooms / large office) | 200W | 8 hrs | 1.6 kWh |
| Ceiling Fans (6) | 420W | 10 hrs | 4.2 kWh |
| Refrigerator | 150W avg | 24 hrs | 3.6 kWh |
| Total Daily Load | ~3.5–5kW average | 31–44 kWh/day | |
A 10-panel (6.5kW) system generates approximately 35–40 kWh on a good summer day. For a large office with computers and a 3 ton AC running throughout the day, 12–14 panels (7.8kW–9.1kW) is recommended to fully cover the load and charge a battery simultaneously.
| System Configuration | Panels | Inverter | Battery | Installed Price |
|---|---|---|---|---|
| Basic — daytime only, no backup 3 ton AC runs only when solar available | 10 × 650W = 6.5kW | Solis 8kW Hybrid | None | Rs. 950,000–1,100,000 |
| Standard — with load shedding backup Recommended 10kWh covers 3–4 hrs fans + lights (not AC) | 10 × 650W = 6.5kW | Solis 10kW Hybrid | Dyness 10kWh | Rs. 1,200,000–1,450,000 |
| Premium — extended backup PowerBrick MAX 16kWh + 12 panels | 12 × 650W = 7.8kW | Solis 10kW Hybrid | Dyness 16kWh | Rs. 1,500,000–1,800,000 |
| Office full coverage 3 ton AC + computers + fridge, all day | 14 × 650W = 9.1kW | Solis 10kW Hybrid | Dyness 10kWh | Rs. 1,600,000–2,000,000 |

A 5kWh battery powers a 3 ton AC (2,500W) for only 2 hours. This is not practical for overnight load shedding. For a 3 ton AC system, skip the 5kWh and go directly to 10kWh minimum.
A 10kWh battery (e.g., Dyness PowerBrick MAX 16.07kWh or 2× Dyness 5kWh stacked) provides approximately 4 hours running a 3 ton AC alone, or 8–10 hours running fans, lights, and computers without the AC. Most office and large home setups choose this approach: AC during solar hours, essential loads from battery at night.
Running a 3 ton AC 8–10 hours/day = ~500–650 units/month in summer. At Rs. 50/unit (high residential or commercial slab), that is Rs. 25,000–32,500/month from 1 AC alone. Over 6 summer months: Rs. 150,000–195,000.
A 10kW solar system (10–14 panels) covers your 3 ton AC and all other daytime loads entirely during solar hours. Estimated annual saving: Rs. 200,000–350,000/year depending on tariff slab. Full payback: 4–5 years. After payback, savings continue for 20+ years.

⚡ Open the Solar Design Tool — FreeYes. A 3 ton AC draws maximum 2,700W — well within an 8kW inverter's capacity. However, if you also want to run computers, lights, fans, and a fridge simultaneously, the combined load approaches 5–6kW. An 8kW inverter handles this with headroom, but a 10kW inverter gives more comfort if total loads regularly exceed 7kW.
A 3 ton AC system (10–14 panels, 8kW–10kW inverter) is excellent for shops, offices, clinics, and showrooms. It covers the AC plus computers, printers, LED lights, and a fridge. With net metering (where available), excess solar generation credits your bill even further.
For 10–14 panels, yes — a site survey is highly recommended. Our engineers assess your roof structure, available space, orientation (south or southwest facing is ideal), and shade from trees or buildings. We provide the survey free of charge for Faisalabad and nearby areas.
LONGi panels: 12-year product warranty + 25-year linear performance warranty. Solis 8kW/10kW inverter: 5 years. Dyness 10kWh battery: 10 years. Mounting structure: 5 years. Saigal Solar installation workmanship: 1 year. Battery BMS and protective devices: 1 year.
