Are you tired of power outages disrupting your daily life? An inverter can be a game-changer, providing reliable backup power for your home.
Before we dive into sizing, let’s quickly recap what an inverter does. An inverter is a device that converts DC (Direct Current) power from batteries into AC (Alternating Current) power that your home appliances use. It’s the heart of your backup power system, working alongside a battery to keep your lights on and appliances running during outages.
Choosing the right inverter size is crucial. An undersized inverter won’t be able to power all your essential appliances, leaving you in the dark when you need power most. On the other hand, an oversized inverter is an unnecessary expense and can be less efficient. The goal is to find that Goldilocks zone – an inverter that’s just right for your needs.

Start by listing all the appliances you want to run during a power outage. Common items include:
– Lights
– Fans
– TV
– Refrigerator
– Computer or laptop
– Mobile phone chargers
Next, you need to calculate the total wattage of these appliances. Look for the power rating on each device or consult your appliance manuals. Add up the wattage of all devices you want to run simultaneously. This gives you your required running wattage.
Some appliances, especially those with motors, require extra power to start up. This is called surge power. For example, a refrigerator might need 600 watts to start but only 150 watts to run. Your inverter should be able to handle the highest surge requirement of your appliances.
Consider any additional appliances you might add shortly. It’s better to have a slightly higher capacity than to outgrow your inverter quickly.
Remember, your inverter works hand-in-hand with a battery. Ensure your hybrid solar inverter battery has enough capacity to support your inverter and power needs for the desired duration.
Now that you know the size, let’s briefly look at the types of inverters available:
– Cheapest option
– Suitable for basic appliances
– Not recommended for sensitive electronics
– Mid-range price
– Work well with most household appliances
– May cause issues with some sensitive equipment
– Most expensive option
– Produces power similar to grid electricity
– Safe for all appliances, including sensitive electronics
For most homes, a pure sine wave inverter is the best choice, especially if you’re powering computers, TVs, or other sensitive electronics.

Stick to reputable brands like Daewoo India known for quality and reliability. A good inverter is an investment in your home’s comfort and safety.
Look for inverters with high-efficiency ratings. More efficient inverters waste less power and can help extend your battery life during outages.
Some inverters can be noisy. If you’re sensitive to sound, look for models known for quiet operation.
Choose a well-ventilated area for your inverter. Good airflow helps prevent overheating and extends the life of your equipment.
Once installed, perform regular checks on your inverter and battery system. Clean connections, ensure proper ventilation, and address any issues promptly.
During an outage, be mindful of which appliances you’re running. Prioritize essential items to extend your backup power duration.
Ensure your chosen inverter is compatible with your battery type (e.g., lead-acid, lithium-ion).
While some DIY enthusiasts might be tempted to install the system themselves, it’s often best to have a professional handle the installation, especially for larger systems.
Choosing the right inverter size for your home doesn’t have to be a daunting task. By assessing your power needs, calculating your required wattage, and considering factors like surge power and future expansion, you can select an inverter that perfectly matches your requirements from Daewoo Electronics.
