Inverters or AC drives are also called variable frequency drives. A consumer can acquire a normal inverter or solar inverter. Such devices, including the different types of solar inverter, convert direct current (DC) to alternating current (AC). There are clear distinctions between solar and normal inverters.

Distinguishing Between Normal Inverters and Solar Inverters

Inverters change voltage from a power source such as a power grid or solar panels. The power goes through a generator as voltage. The inverter changes that voltage to align with the voltage required by a load.

The following are considerations factored in when distinguishing between normal inverters and solar inverters:

Source of Power

Solar and normal inverters work depending on the source of power that they convert. Normal inverters often use power from the local power grid. Solar inverters convert power generated from a solar system by solar panels. These energy sources generate DC power, which the inverters convert to AC power that businesses and homes use for electricity-based tasks and appliances.

The carbon footprint policy reflects another implication of the inverter type and its energy source. Normal inverters work with electricity, which is a non-renewable energy source. Solar inverters rely on sunlight, which is clean energy. As such, solar inverters become part of mitigating pollution and the subsequent impact of climate change.

Reliability of Power Supply

Normal inverters require a consistent or constant supply of electricity. Such power comes from electricity from a local grid. This inverter does not store surplus energy. On the other hand, solar inverters store excess energy from solar panels for use later when the sun is not shining. Some solar inverters work as backups during power outages.

 Solar inverters work with solar panels only and remain ideal in areas with unreliable electricity supply. They promote the use of solar power in areas that receive a lot of sunlight. Solar inverters reduce over-reliance on grid power supply, which gives consumers more independence from unpredictable grid outages.


Solar inverters function best with DC power sources. Of the solar inverters available, some connect to individual solar panels. Then, such inverters make a power system more efficient and flexible.

Solar inverters convert higher amounts of DC power to AC than normal inverters. That translates to the solar inverters’ ability to optimise the solar panel’s ability to produce power. It makes homes and businesses energy efficient. Normal inverters do not optimise energy production but only convert what the local grid avails.

Financial Implications

Normal inverters cost less than solar inverters. Solar inverters work with solar systems only. Normal inverters do not require a connection to solar panels. They are connected to batteries that store solar power during grid power outages, making them versatile and cheaper. 

The drawback is that normal inverters do not function optimally with other power sources besides the grid. Normal inverters are easier to install and maintain than solar inverters, which work with solar panels only.

Solar inverters have higher maintenance costs because they require specialised care and servicing. They are not common on the market as they are only dedicated to solar energy supply. That, too, contributes to the higher upfront costs for solar inverters.

 Nevertheless, the higher efficiency of solar inverters converts to better returns on the solar inverters. Their functionality in converting more quantities of solar energy to AC and storing surplus use for later leads to reduced power bills over time.


The two main types of inverters are modified and pure sine wave inverters. Yet, consumers seek these as solar inverters and normal inverters. They facilitate the functioning of devices that depend on AC power generated through solar panels or a battery bank.
