Home > String Inverter: What It Is, How It Works, and Benefits A string inverter is a central component in solar energy systems, responsible for converting direct current (DC) electricity generated by solar panels into alternating current (AC) electricity that can be used in homes or businesses.
The functioning of a solar string inverter relies on monitoring the voltage and current from the solar panel string. It adjusts the operation point to extract the maximum possible power, using algorithms like Maximum Power Point Tracking (MPPT). The converted AC power is then sent to the main electrical panel for distribution.
Key Features of a String Inverter: Proper string inverter installation is crucial for optimal performance. It involves connecting multiple solar panels in series and ensuring that the total voltage does not exceed the inverter’s specifications.
Here are the results we calculated: This inverter has 2 MPPT trackers, so a total of 2 strings can be connected to the inverter. We know that there can only be 13 modules maximum installed. We can have one MPPT with 6 modules in a string and the other at 7 modules in a string. Check out UpTop Solar String Sizing Tool that does this for you!
