A solar inverter is the brain of the solar system, not only does it convert DC electricity generated by solar panels into useful AC electricity, but it also provides important technical information required for solar system operation and maintenance crews to fix PV system errors. Additionally, if there are batteries present in a PV system, the solar inverter is responsible for managing these batteries.
Solar inverters fall into three categories, as follows:
Rather. Inverters that power the entire system
Activ solar's inverter is able to handle multiple strings at once and has a large capacity. By using a combiner box you can connect a number of solar strings together, and then you can connect the output of the combiner box to the inverter. Developed solar central inverters do not require a combiner box since the inverter has multiple input terminals and is capable of handling multiple string output voltages.
The second. Inverter with strings of solar cells
Inverters with this power capacity work on strings, so they are not as powerful as central solar inverters. With 30 solar panels, we can divide them into five strings, which equals six solar panels per string. Solar systems will have multiple strings of inverters, together with solar strings.
Due to two factors, this system will be more efficient than a central solar inverter with higher AC energy harvest.
So the array of string inverters will be more efficient, produce more energy, but will be more expensive than the single inverter array. A string inverter system may also be more reliable if more than one inverter is used.
Three. Microinverters for solar power
The module scale inverter has a lower power capacity than string inverters. Micro inverters convert DC to AC for each solar panel. The shaded panels will not affect other panels, and also we can adjust the tilt angle and azimuth for each panel, allowing us to harvest more energy. Clearly, this system is more efficient than string inverter systems.
In the end, it's clear that microinverter systems harvest AC energy more efficiently than string inverters and central inverters. However, they are more expensive.
