The series configuration refers to the integration of multiple photovoltaic modules in series and parallel to form a complete
photovoltaic array，Then input into the Aipangde controller，The controller provides real-time maximum power point
tracking(MPPT)for the busbar。
Take eight photovoltaic panels as an example，Four photovoltaic modules are connected in series to form a group，The
two groups are connected in parallel and share the same input；the wiring is shown in the figure below：
