SUN2000 Smart PV Optimizer
User Manual

2.2 Product Introduction

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.

Application Scenario
Full configuration: All PV modules are connected to optimizers.
In this scenario, the MPPT function, module-level shutdown and monitoring, and
long-string design are supported.

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: If all PV modules are configured with optimizers, a PV string
can contain more PV modules than a conventional PV string.

● To ensure that the optimizer is successfully connected to PV modules, select PV modules
whose output power cables meet the length requirements.
● To minimize electromagnetic interference, minimize the distance between the positive
and negative cables of an optimizer.
● To ensure reliable communication between the inverter and optimizer, the AC and DC
power cables of the inverter must be at least 10 cm away from the AC power cables of
motor-type impact loads, such as air conditioners and elevators. It is recommended that
the cables be routed in different troughs or pipes.
