DC 2+2 string 1000Vdc photovoltaic field panel for 2 MPPT with miniature circuit breakers and surge arresters
The DC 2+2 string 1000Vdc photovoltaic field panel for 2 MPPT is an electrical panel designed for the protection, isolation, and distribution of photovoltaic strings on the DC side in photovoltaic systems with inverters equipped with dual MPPT.
The panel allows the management of four photovoltaic strings configured in a 2+2 mode for two independent inverter MPPT inputs, ensuring electrical protection and operational safety of the system.
The presence of dedicated miniature circuit breakers for each string group and Type 2 surge arresters ensures the protection of the photovoltaic modules and the inverter from overcurrents and transient overvoltages on the DC side.
Function of the DC field panel in photovoltaic systems
The DC field panel represents the collection and protection point for photovoltaic strings before they enter the inverter. Its main function is to ensure the correct isolation of the lines, protection against overcurrents, and safeguarding of the system components.
In photovoltaic systems with inverters equipped with multiple MPPT trackers, the panel allows for the separate management of the strings, improving energy conversion efficiency and system stability.
The surge arresters installed on the DC side protect the system from overvoltages caused by atmospheric phenomena or electrical maneuvers on the grid, helping to increase the overall reliability of the photovoltaic system.
The field panel also allows for the orderly management of electrical connections and facilitates system maintenance and inspection operations.
