Are you looking to invest in an inverter? Confused about choosing the right size? Crown Micro Global offers you the best selection tips before the installation of the Crown Inverter. Invest wisely by selecting the proper size of inverter, avoiding large inverters that increase solar panel and battery costs or small ones that can't handle your load.

Installing an inverter means managing your load and ensuring complete backup, as it's a significant investment, so choosing the wrong size can be risky. In this blog, you'll learn about selecting the correct solar inverter size that offers stability, uninterrupted connectivity, and smooth operation for your home and commercial spaces.

Why do you need the right solar size?

Crown solar inverters are solutions to overcome outage and fluctuation issues, especially in Pakistan. But we can't deny that it's an expensive investment upfront, which can be an initial burden on your pocket. However, this cost will be justified through long-term savings on your bills. If your installed inverter cannot properly manage your load, you won't be able to run your appliances, and with heavy loads, it will beep and shut off. Many people think inverter faults cause this, but it's a result of incorrect size selection.

Installing a small inverter in a larger household with air conditioning creates challenges. To avoid these issues, selecting the right inverter size is crucial.

Avoid Overloading the Inverter

If your inverter is too small, it won't properly handle your appliances, causing frequent shutdowns, overheating, and potential system damage. To save on bills, you might invest more in a new inverter.

Prevent Wasting Money

Purchasing an inverter is a costly investment intended to resolve outages, blackouts, and voltage surges. However, buying the wrong inverter, such as a 10 KW setup for a 3 KW load, means you'll need extra investments in additional panels and batteries to create a smooth solar system. This results in wasted money, as excess energy may go unused. To avoid this, purchase an inverter that correctly matches your load needs.

Efficient Energy Conversion

Purchasing an inverter means you need efficient conversion, and your inverter should match the capacity of your system. With Crown Solar Inverters, you benefit from efficient conversion when you install the correct inverter size; otherwise, most inverters lose energy even in an idle state.

 

Increase System Lifespan

A balanced inverter setup (panel + battery + inverter size) maximizes energy output without causing stress, leading to a longer lifespan for both the inverter and the battery.

 

Inverters offer reliable backup solutions for homeowners and businesses to generate power directly from solar panels. They convert solar energy into DC power, providing your appliances with cost-free electricity without paying bills. All this is achievable when you select the correct size of solar inverter. Choosing a small inverter cannot fulfill your energy demands and won't save on your bills. Conversely, going for a larger inverter raises the initial cost, especially considering solar panel prices in Pakistan, which depend on inverter size. 

Steps to Select the Right Inverter SizeCalculate Your Energy Consumption

Start by calculating your energy usage. Before purchasing an inverter, check your bill for units in kWh. For example, if your bill shows 30 kWh, divide it by 30 days: 

For instance, if your total is 300 units,

Your daily energy use is calculated as:

300 ÷ 30 × 1000 = 10,000 Wh/day.

It means your average daily energy consumption is 10 kWh.

Identify Peak Loads

Knowing your peak load is crucial since you'll supply energy to all appliances at once. List your loads on paper before purchasing an inverter. For example:

2 Fans = 150W each 300W

Bulbs = 20W each 200W

Refrigerator = 400W

1.5 Ton AC = 1500W

Total load = 2400W (2.4 kW)

Your demand is 2.4 kW. However, when you run the microwave oven and washing machine simultaneously, the requirement increases to about 5 kW. A 5 kW inverter would be needed in that case. If you manage your loads effectively and run only one heavy appliance at a time, a 3 kW inverter can handle your needs. 

Match Inverter with Solar Panel Size

Solar panels generate energy from the sun. When installing an inverter, it should be compatible with your panels. Many companies place restrictions on panel selection, but Crown Inverters are designed to be compatible with any solar panel. You can choose from brands like LONGi, Canadian Solar, or ZN Shine Panels, all available from Crown Micro, which offers a range suitable for various budgets and energy efficiencies.

To select the best solar panel in Pakistan based on your load, calculate your daily usage against sun hours and system efficiency. For example, if you need 10,000 Wh and the average peak sun hours in Pakistan are 5 hours, with an inverter efficiency of 80%, your required inverter size is: 

10,000 ÷ (5 × 0.8 × 1000) ≈ 2.5 kW. 

So, you'd need about 2.5 kW of solar panels. Pairing these with a Crown 3kW inverter ensures maximum energy production even on cloudy days.

 

Consider Battery Backup

For hybrid solar inverter Lahore, you need batteries sized according to your load and backup time. You can use any batteries, such as lithium or gel, but the setup depends on whether you have a 12V system or a 48V system. Typically, four batteries are required to create a 48V system.
