Huawei MERC-1100W-P User Manual

2 Product Introduction
2.1 Overview
The smart PV optimizer is a DC to DC converter which implements maximum
power point tracking (MPPT) of each PV module to improve the energy yield of
the PV system. It enables module-level shutdown and monitoring, and supports
long-string design.
Functions and Features
● Module-level MPPT: Implements maximum power point tracking of each PV
module to improve the energy yield of the PV system.
● 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
congured with optimizers, a
PV string can contain more PV modules than conventional PV strings.
