Tips: 3 different types of solar inverters
1. Central solar inverter
It’s a large power capacity solar inverter that can handle more than one string. A number of solar strings will be connected together via a combiner box, and then the DC output of the combiner box will be connected to the inverter. With solar central inverters industry development, there is no need for the combiner box as the inverter becomes having more than one input terminals with the capability to handle different strings output voltages.
2. String solar inverter
This inverter power capacity is lower than central solar inverter, it works on string scale. For example, if we have 30 solar panel in the array, it can be divided to 5 strings, which means 6 solar panel per string. For each string, there will be a solar inverter, hence the solar system will have multiple string inverters.
3. Solar micro inverter
This inverter power capacity will be lower than string inverter, it works in module scale. For each solar panel, there will be micro inverter attached to it and converts DC to AC. Of course, this system will be more efficient than string inverter system as shaded panel will not affect other panels, also we can make different orientation for each panel “tilt angle and azimuth”, so can harvest more energy.
