How to choose the right inverter for your home: the key to powering your home solar system

Solar energy systems are becoming a popular renewable energy solution in modern homes. As an important part of a solar system, the inverter assumes the key role of converting DC power to AC power. In this article, we’ll explore the features of inverters, selection criteria, and factors that affect the user experience.

What is an inverter?

An inverter is a device that converts DC power (e.g., energy stored in batteries) into AC power for use in domestic or industrial equipment. Additionally, it can charge batteries from an AC power source, such as the utility or a generator. Inverters not only improve power utilization, but also enable off-grid power supply and uninterruptible power supply (UPS) functions.

Inverter power and appliance use

The power of an inverter is usually expressed in kilowatts (KW) or “P”. A 3KW inverter, for example, can provide about 3,000 watts of power. Below are the wattages of some common appliances to help users estimate how many can be used at the same time:

• LED lights: 10-15 watts (200-300 can be used simultaneously)
• TVs: 100-300 watts (10-30 can be used simultaneously)
• Refrigerator: 150-300 watts (can use 10-20 units simultaneously)
• Washing machine: 300-1500 watts (usually 2-3 units can be used)
• Microwave oven: 800-1200 watts (can use 2-3 units)
• Air conditioner: 1P equals about 2500 watts depending on the cooling capacity (e.g. 1.5P is about 3750 watts).

When choosing the right inverter, users need to consider the power of common household appliances to ensure that they will not be overloaded.

Points to note when choosing an inverter:

Customers may encounter the following problems when using the inverter, which may lead to their negative feedback on the device:

1. Insufficient performance: If the power of the inverter is not enough to meet the household’s electricity demand, it may affect the stability of the power supply.
2. Installation problems: Improper installation or incompatible accessories may lead to performance degradation.
3. System configuration: Mismatched batteries or improper load management may affect the proper functioning of the inverter.
4. Equipment failure: Failure of the inverter itself or software problems may also lead to poor performance.
5. User expectations: Users have high expectations of the inverter and the actual experience fails to meet their expectations.

Summarize

Inverters play a critical role in solar systems. Understanding the inverter’s features, power, and factors that affect the user experience can help consumers make more informed choices. By properly configuring appliances and inverters, users can take full advantage of solar energy and enjoy a sustainable power supply.
