instructions in this document are only supplements to local laws and regulations.

Do not operate the product or handle cables during thunderstorms.

Before operating the product, remove any conductors such as jewelry or watches.

Use insulated tools during operations.

Bolts should be tightened with a torque wrench and marked using red or blue color.

Installation personnel should mark tightened bolts in blue. Quality inspection personnel

should confirm if the bolts are tightened and then mark them in red. If screws or bolts

used to secure the device are not tightened to the required torque, the device may fall

from the mounting bracket.

Follow specified procedures during installation and maintenance. Do not attempt to alter

the device or deviate from the recommended installation procedures without prior

consent from the manufacturer.

Install the product in strict accordance with the quick guide.

If the optimizer needs to mounted onto a PV module frame, use the

TSM-XXXDD05A(II), TSMXXXDD05A.05(II), TSM-XXXDD05A.08(II), or

TSM-xxxPD05.50 series PV modules from Trina Solar Co., Ltd.

If the optimizer needs to be mounted onto a PV module support, ensure that the opening

width of the support is 10.5–14.0 mm and the thickness is 3–7 mm.

and meet all specification requirements.

The output wiring terminals of the optimizer cannot be hot swapped. If the terminals are

hot swapped, the optimizer may be damaged.

Operation

High voltagemay cause an electric shock, which results in serious injury, death,or serious

property damage from the optimizer in operation. Strictlycomply with the safety precautions

in this document and associateddocuments when operating the optimizer.



Donot touch an energized optimizer because it has a high temperature.

Follow local laws and regulations when operating the device.

Maintenance and Replacement

High voltage may cause an electric shock, which results in seriousinjury, death, or serious

property damage from the optimizer in ore, before maintenance, power off

the optimizer and strictlycomply with the safety precautions in this document and

associateddocuments to operate the optimizer.



Maintain the optimizer with sufficient knowledge of this document and propertools and

testing devices.

Temporary warning signs or fences must be placed to prevent unauthorized people from

entering the site.

The optimizer can be powered on only after all faults are rectified. Failingto do so may

escalate faults or damage the device.

During the maintenance, observe ESD precautions and wear ESD gloves.

SUN2000-375W-USP0 Smart PV Optimizer

User Manual 2 Overview

2.1 Product Overview

Figure 2-1 Optimizer

Overview

The optimizer is a DC-DC converter installed on the back of PV modules in a PV system. It

tracks the maximum power point (MPP) of each PV module to improve the energy yield of

the PV system, and performs the functions of module-level shutdown, module-level

monitoring, and automatic positioning.

2.2 Working Principles

Conceptual Diagram

The input port of the optimizer connects to the PV module. Through a DC/DC circuit, the PV

input voltage is converted into a required voltage and the maximum power point tracking

(MPPT) function is implemented.

SUN2000-375W-USP0 Smart PV Optimizer

User Manual 2 Overview

Figure 2-2 Conceptual diagram

Functions



Module-level MPPT: The optimizer improves the energy yield of the PV system by

continuously tracking the MPP of each PV module.

Module-level shutdown: The optimizer cuts off the voltage of each PV module.

Module-level monitoring: The optimizer monitors the operating status of each PV

module.

Automatic physical positioning: The optimizer determines the PV module location by

automatic physical positioning.

2.3 Application Scenario

The optimizer is mandatory and used for all PV modules. It performs the functions of MPPT,

module-level shutdown, monitoring, and automatic positioning.
