Solar power inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.
The ACDB receives the AC power from the solar inverter and directs it to AC loads through the distribution board. Where, DCDB is used to protect the system if there is any fault during failure in DC side.
Array Junction Boxes provide interconnection between the input leads from the solar PV modules, and the output lead to the re-combiner box or inverter.
