What is a solar panel inverter
A solar inverter is a critical component of a solar energy system. A solar inverter transforms the energy generated byinto usable electricity that can be used in your house or business.
A solar inverter converts the variable direct current, or ‘DC’ output from yours to alternating current, or ‘AC’ output. The appliances in your home operate on alternating current, not direct current, which is why the solar inverter must convert the direct current generated by your solar panels to alternating current.
Solar inverter types
There are a few distinct inverter manufacturers, however, the majority specialize in one of the inverter types listed below. We’ve arranged them in ascending order, beginning with the types that have the fewest features and ending with the types that have the most features.
The inverter you receive will be determined by a variety of criteria, including the amount of shade your home receives, the intended usage of your solar inverter, and/or the utility regulations for residential solar in your location.
1- Straight string inverter
For many years, the only choice was a string inverter. One of the primary reasons for this is that it has fewer overall upfront expenses and requires less long-term upkeep (since there is only one point of failure).
Therefore, if your home has various roof planes or a dense forest surrounding it, a straight string inverter may not be the best option. However, if you live in an area that is typically sunny and your home has a south-facing roof, a straight string inverter may be the best option for you because you will benefit from the simplicity of the system and will save some money.
2- Optimized string inverter
The optimized string inverter is similar to the normal string inverter except that it has power optimizers beneath each rooftop solar panel. By monitoring and then transmitting the performance of each solar panel individually, the power optimizer transforms the solar panel into a “smart panel” and maximizes performance. This enables you to get the most amount of power from your equipment. Generally, optimized string inverters outperform straight string systems.
Rather than a single huge inverter located on the exterior of the home, a microinverter is installed beneath each solar panel on the roof (similar to the way power optimizers are installed). By providing each panel with its own microinverter, design freedom is increased (technically, a person could install a system with one microinverter, and then add on later as needs arise). Additionally, the microinverter transforms DC to AC on-site, whereas the optimizer transmits DC energy to the string inverter, which then converts DC to AC.
4- Hybrid inverter
Hybrid Inverters are inverter technology’s “New Kid on the Block.” A hybrid inverter is a device that combines a photovoltaic (PV) inverter and a battery inverter. They are available in straight string and optimized string configurations. This is becoming a popular alternative for homeowners interested in energy backup choices (even if they are not yet ready to install a battery) because it significantly reduces the cost of adding a battery.
A solar panel inverter can help maximize your energy production and monitor your system’s output. They can also detect faults that might otherwise damage your. Inverters can also communicate with the utility grid to ensure electricity is not lost or damaged during a power outage.
