The basic structure of a PV ground-mounted system, whether with a central inverter or string inverter, is the same for all of them. In a central inverter system, the solar panels are connected to each other as a string, which in turn is connected to the PV DC combiner boxes. All these combiner boxes are connected to a central inverter, which then converts the direct current into alternating current. The only difference with the string inverter system is that the strings are connected directly to the string inverter input. To learn more about the specific differences between central inverters and string inverters in a ground-mounted PV system and whether DC combiner boxes can also be used with 1 MPPT string inverters, please read the fact sheet.
