Mini/Micro Solar Inverters: Advantages, Disadvantages, Cost, and More

Inverters back the continuous supply of energy provided by the solar panels. Therefore, it is important to choose the right inverter if you decide to go for solar energy. The mini solar inverter belongs to the latest technology of inverters providing reliability and efficiency. 

What Is A Mini Solar Inverter?

A solar panel micro inverter is a mini device responsible for converting Direct Current (DC) to Alternating Current (AC). 

It makes sure that the energy generated by the solar panels is converted to usable power. It can generally handle the power output of a single solar panel. 

How Does A Mini Solar Inverter Work?

A mini solar inverter generates electricity by converting the DC output received from the solar panels into AC output. 

The sun rays are captured by the solar panel, composed of silicon or thin-film layers that act as semiconductors. 

These layers have both positive and negative atoms. When the sun’s rays hit the semiconducting layers of the solar panel, the power is sent to the photovoltaic cells. 

The power then comes in contact with the negative and positive energy and produces electricity called the Direct Current (DC). 

The energy is stored or sent back to a solar panel micro inverter that converts the DC into AC because houses require Alternating Current to power appliances. 

What Does A Mini Solar Inverter Do?

Micro inverters for solar panels are required for the system to function efficiently.

• The most important function of a mini solar inverter is to convert direct current to alternating current to make it usable.
• Mini solar inverters help in maximising the power output for maximum efficiency. They determine the maximum energy the system can handle. 
• If a solar system fails due to internal or environmental issues, the mini solar inverter can recognise the fault and send signals accordingly. 
• The mini solar inverter comes with smart technology that has certain specifications like controlling voltage and frequency. 
• One of the crucial functions of a  solar micro inverter is that it can function even during voltage disturbances without affecting the power flow. 
• The mini solar inverter helps keep track of the solar system’s output. The most recent mini solar inverters come with features like WiFi and Bluetooth. With the help of these facilities, you can view power reduction statistics as well.

Advantages of A Mini Solar Inverter 

• Mini solar inverters are attached to every solar panel individually. It means that even if one micro inverter solar panel stops working, this doesn’t affect the system’s efficiency. Naturally, they are very reliable for continuous power supply.
• Tracking Mini solar inverters isn’t a problem because you can solve the issues remotely without visiting the site yourself. 
• Every solar panel produces power independent of the other. Therefore a shaded solar panel will not affect the efficiency of the other solar panels.
• The micro inverter for solar panels is a compact module that can be easily tucked under a solar panel. Because of their small size, central inverters do not require separate cooling. As a result, there is less heat loss, and it operates without making noise. 
• Maintaining a mini solar inverter isn’t a hard deal because it can be monitored using apps that come with the inverter.
• Solar micro-inverters can last longer than traditional central inverters because they are not subjected to high temperatures and power loads. They have a shelf life of 20 to 25 years. 
• With solar micro inverters, you may subsequently expand your solar system with extra solar panels. You don’t need to bother about installing another inverter.

Disadvantages Of A Mini Solar Inverter 

• Mini solar inverters have the disadvantage of a higher initial cost. Because every inverter is positioned separately under a solar panel, there is an additional requirement for monitors. 
• The mini solar inverters have higher maintenance costs and a high replacement price. 

Solar Mini Inverter Price

A single-phase micro inverter price can start from ₹9000. Micro inverters cost higher than central inverters. 

Solar systems with mini inverters are easier to install and take less time, saving up to 15% on installation expenses.

Please Note: There are no fixed prices. Every model is different and so is every brand. Hence, the price of solar mini inverters may vary substantially. 

What To Look For While Buying a Mini Solar Inverter?

Below are a few points to consider when buying Mini Solar Inverters.

Warranty: It is important to check for warranties while buying a mini solar inverter. 

When choosing a manufacturer, you should understand what is and what is not covered in the guarantee period. Knowing whether an internal issue will be covered or not is crucial.

Efficiency: There are two things to focus on – Weighted efficiency and Peak efficiency. 

Peak efficiency indicates your inverter’s efficiency when operating at maximum capacity. Weighted efficiency focuses on input levels of direct current. 

Conclusion 

There are many advantages to using a mini solar inverter. It usually has a higher cost compared to central inverters. 

However, micro inverters are an ideal choice for saving extra energy. The houses that receive low sunlight or are shaded are most likely to profit from micro-inverters. 

Mini solar inverters are also excellent for roofs with limited space. They provide a better payback throughout the system’s life in commercial setups where monitoring the performance is necessary.

FAQs

Q1. What can damage a mini solar inverter?

Overusing any solar inverter can cause damage. A mini solar inverter is no different – above its specific limits, it can lead to bridge failure. Regular preventative maintenance is important for longer shelf life. 

Q2. What is the life of micro-inverter solar panels?

Mini solar inverters can usually last for 20 to 25 years, depending on their usage. They usually have a longer shelf life.

Q3. Are the mini solar inverters worth it?

Yes, mini solar inverters are worth the money. The most important factor is that even if one solar panel fails, you will have continuous power because mini solar inverters are individually connected to the grid. 

The installation cost might be higher than regular inverters, but the mini solar inverters last for a good 20 years, which makes them cost-effective.
