Module-level shutdown: Adjusts the module output voltage to a safe range
when the output is disconnected or the inverter shuts down.
Module-level monitoring: Monitors the operating status of each PV module.
Long PV string supported: If all PV modules are configured with optimizers, a
PV string can contain more PV modules than conventional PV strings.
