Welcome to our inverter information page! If you're considering installing a solar panel system, you've probably heard about inverters. Inverters are an essential component of any solar panel system, as they convert the DC power generated by your solar panels into the AC power that can be used in your home or business.

How do inverters work ?

Inverters work by taking the DC electricity produced by the solar panels and passing it through a device called a transformer, which converts the DC power into AC power at the appropriate voltage and frequency for use in your home or business. The inverter also monitors the output of the solar panels to ensure that the voltage and current remain within safe levels, and can shut down the system in the event of a fault or outage. Your choice of inverter will depend on factors like your energy needs, the size and orientation of your solar panel system, and your budget.

Different Types of Inverters for Solar Panel Systems:

There are several types of solar inverters, each with its own advantages and disadvantages. Here are the most common types of inverters used in solar panel systems:

String Inverters

String inverters are one of the most common types of inverters used in solar panel systems and are suitable for smaller solar panel systems.. They work by connecting multiple solar panels together in a series (or "string"), and then converting the DC electricity produced by the string into AC electricity for use in your home or business.

One of the main advantages of string inverters is their affordability. They are generally less expensive than other types of inverters, making them a popular choice for residential and small commercial solar panel systems. They are also relatively simple to install and maintain, and can be easily upgraded or expanded if your energy needs change in the future.

However, string inverters do have some limitations. Because they rely on a series connection of solar panels, the output of the entire string can be impacted by factors like shading or soiling on just one panel. This means that if even one panel in the string is underperforming, it can significantly reduce the overall output of the system.

Additionally, string inverters typically have a single MPPT (maximum power point tracking) input, which means that they can only optimize the output of the entire string, rather than individual panels. This can result in less efficient performance overall.

Micro inverters

Micro inverters are another type of inverter used in solar panel systems. Unlike string inverters, micro inverters are installed on each individual solar panel, rather than in a centralized location. They convert the DC electricity produced by each panel into AC electricity, which can then be used in your home or business. Microinverters offer greater flexibility and efficiency, as they allow each panel to operate independently.

One of the main advantages of micro inverters is that they optimize the output of each individual solar panel, rather than the entire string. This means that factors like shading or soiling on one panel will not impact the output of the rest of the panels in the system. As a result, micro inverters can offer higher overall energy yields and better performance in partially shaded or complex rooftop configurations.

Another advantage of micro inverters is their modularity. Because each panel has its own inverter, the system can be easily expanded or upgraded by simply adding more panels and micro inverters as needed. This also means that if one micro inverter fails, it does not impact the performance of the rest of the system.

However, micro inverters can be more expensive than string inverters, and their installation and maintenance can be more complex. Because each panel has its own inverter, there are more components to install and manage, which can increase the overall cost and complexity of the system.

Power Optimizers

Power optimizers work by managing the DC electricity output of each solar panel and adjusting it to the optimal voltage for the entire system. They do this by communicating with a central inverter, which then converts the DC electricity to AC electricity that can be used in your home or business.

These are similar to microinverters, but they are installed at the panel level and optimize the DC power output from each panel. Power optimizers are often used in larger solar panel systems.

One of the main advantages of power optimizers is that they can help mitigate the effects of shading or soiling on one or more solar panels. By optimizing the output of each individual panel, power optimizers can help maximize the overall energy yield of the system, even in less-than-ideal conditions.

Another advantage of power optimizers is their modularity. Because each panel has its own optimizer, the system can be easily expanded or upgraded by simply adding more panels and optimizers as needed. This also means that if one optimizer fails, it does not impact the performance of the rest of the system.

However, like micro inverters, power optimizers can be more expensive than traditional string inverters, and their installation and maintenance can be more complex. They also require an additional component (the central inverter) to function, which can add to the overall cost of the system.

Hybrid Inverters

Hybrid inverters are a type of inverter technology that can manage both solar energy and energy from the electric grid or a battery backup system. This makes them a popular choice for homeowners and businesses who want to maximize their energy independence and efficiency.

These are designed for solar panel systems that are connected to a battery backup system. Hybrid inverters allow excess energy to be stored in the battery bank, which can be used during periods of low solar production or during power outages.

Hybrid inverters work by converting the DC electricity produced by your solar panels into AC electricity that can be used in your home or business. They can also manage the flow of electricity between your solar panels, battery backup system (if you have one), and the electric grid.

One of the main advantages of hybrid inverters is that they can help reduce your dependence on the electric grid, which can lead to significant savings on your energy bills over time. They can also provide backup power in the event of a power outage, which can be especially valuable for homeowners and businesses in areas with unreliable power grids or frequent outages.

Another advantage of hybrid inverters is their ability to integrate with battery backup systems. By storing excess solar energy in batteries during the day and using that energy at night or during periods of low solar production, you can further reduce your reliance on the electric grid and maximize your energy independence.
