How to Choose the Right Inverter Size for Your Home Solar System in Pakistan

Looking for the best solar inverter for home in Pakistan? Learn how to choose the right inverter size, price details, and why Inverex hybrid inverters from IMH Technologies are the smart choice in 2025.

As solar energy adoption grows rapidly, more households in Pakistan are shifting towards sustainable solutions to reduce electricity bills and avoid load-shedding. The heart of every solar power system is the solar inverter—it converts DC electricity generated by solar panels into usable AC electricity for home appliances.

Choosing the right solar inverter for a home in Pakistan is crucial for efficiency, reliability, and long-term performance. At IMH Technologies, a wholesale dealer of Inverex solar products, we help homeowners select the ideal inverter size to match their energy needs.

Why Inverter Size Matters

An inverter that is too small won’t handle your energy load, while one that is too large will be unnecessarily expensive and less efficient. The correct inverter size ensures:

• Efficient power conversion

• Maximum performance of solar panels

• Longer system lifespan

• Reliable backup during load-shedding

Step 1: Calculate Your Daily Energy Consumption

Before choosing an inverter, estimate how much electricity your household consumes daily. Check your monthly electricity bill for kWh usage, or calculate based on major appliances such as fans, lights, refrigerators, ACs, and washing machines.

Example:

• Fan: 70–90W × 5 hours/day

• LED Lights: 10–15W each × 5 hours/day

• Refrigerator: 150–200W × 24 hours/day

• Air Conditioner: 1.5–2 kW × 6–8 hours/day

This will give you a rough idea of your total energy demand.

Step 2: Match Inverter Size with Solar Panel Capacity

A general rule is that the inverter capacity should be close to the total solar panel capacity. For example:

• 3 kW solar panels → 3 kW inverter

• 5 kW solar panels → 5 kW inverter

• 10 kW solar panels → 10 kW inverter

In some cases, a slightly smaller inverter (90–95% of panel capacity) is acceptable, as panels rarely produce their full rated output.

Step 3: Consider Your Backup Needs

In Pakistan, load-shedding remains a challenge. If you want backup during outages, consider a hybrid solar inverter paired with batteries.

• On-Grid Inverters—Best for reducing bills with net metering, no backup.

• Off-Grid Inverters – For areas with no electricity access, completely independent.

• Hybrid Inverters—Best choice for homes, combining net metering with battery backup.

At IMH Technologies, we recommend Inverex hybrid inverters as the ideal solar inverter for homes in Pakistan, offering both reliability and flexibility.

Step 4: Plan for Future Expansion

If you plan to add more solar panels or appliances in the future, choose an inverter with slightly higher capacity to allow easy system expansion. This ensures you won’t need to replace your inverter when upgrading.

Solar Inverter Price in Pakistan (2025)

The cost of a solar inverter for a home in Pakistan depends on type, brand, and capacity. On average:

• 3–5 kW On-Grid Inverters: PKR 150,000 – 250,000

• 5–10 kW Hybrid Inverters: PKR 250,000 – 600,000

• Large 10–15 kW Inverters: PKR 600,000+

Inverex inverters are among the most trusted in Pakistan, combining efficiency, affordability, and local warranty support.

Frequently Asked Questions (FAQs)

1. Which solar inverter is best for a home in Pakistan?

The best solar inverter for a home in Pakistan depends on your energy needs. For most households, a hybrid inverter is the ideal choice because it allows you to use solar energy during the day, store extra power in batteries, and benefit from net metering. Among brands, Inverex hybrid inverters are highly recommended for their efficiency, durability, and local warranty.

2. How many kW solar inverters do I need for a house?

The inverter size depends on your energy consumption and solar panel setup. For a small home, a 3–5 kW inverter is sufficient. Medium-sized homes often require a 5–7 kW inverter, while larger homes with multiple ACs and appliances may need 10 kW or more. It’s best to match your inverter size with the capacity of your solar panels.

3. What is the average solar inverter price in Pakistan (2025)?

The solar inverter price in Pakistan in 2025 varies by type and capacity:

• On-Grid Inverters: PKR 150,000–250,000 (3–5 kW)

• Hybrid Inverters: PKR 250,000–600,000 (5–10 kW)

• Large Inverters: PKR 600,000+ (10–15 kW)
  Prices also depend on brand. Inverex solar inverters, available at IMH Technologies, are competitively priced with full warranty support.

4. Can I run my home completely on a solar inverter?

Yes, with the right system size, it’s possible to run your home entirely on solar. For complete independence from the grid, you’ll need a hybrid or off-grid inverter, solar panels, and sufficient battery storage. However, most homeowners prefer a grid-tied hybrid system that provides backup during load-shedding and also reduces bills through net metering.

5. Why should I buy an Inverex solar inverter for my home?

Inverex solar inverters are among the most trusted in Pakistan. They are energy-efficient, compatible with net metering, and available in multiple capacities to suit different home sizes. At IMH Technologies, we supply original Inverex inverters with a warranty, making them a safe and long-term investment.
