Chapter 2 Preparation

2.1 Safety Instructions

DANGER

· Dangerous due to electrical shock and high voltage.

· Do not touch the operating component of the inverter, or it might result in burning or
death.

· To prevent risk of electric shock during installation and maintenance, please make sure
that all AC and DC terminals are plugged out.

· Do not touch the surface of the inverter while the housing is wet, or it might lead to
electrical shock.

· Do not stay close to the inverter while there are severe weather conditions including
storm, lighting, etc.

· Before opening the housing, the SAJ inverter must be disconnected from the grid and PV
generator; you must wait for at least five minutes to let the energy storage capacitors fully
be discharged after disconnecting from power source.

WARNING

·The installation,service, recycling and disposal of the inverters must be performed by
qualified personnel only in compliance with national and local standards and regulations.

·Any unauthorized actions including modification of product functionality of any form
may cause lethal hazard to the operator, third parties, the units or their property. SAJ is not
responsible for the loss and these warranty claims.

·The SAJ inverter must only be operated with PV generator. Do not connect any other
source of energy to the SAJ inverter.

·Be sure that the PV generator and inverter are well grounded in order to protect safety of
people’s life and property.

CAUTION

·The PV inverter will become hot during operation. Please do not touch the heat sink or
peripheral surface during or shortly after operation.

·Risk of damage due to improper modifications.

NOTICE

·Public utility only

·The PV inverter is designed to feed AC power directly to the public utility power grid; do
not connect AC output of the inverter to any private AC equipment.

Chapter 3 Product Information

3.1 Application Scope of Products

Suntrio Plus series products are grid-tied three phase inverters without

transformers, and the inverters are important components of grid-tied solar power

systems.

The Suntrio Plus inverters change the DC generated by solar panels into AC which

is in accordance with the requirements of public grid, and send the AC into the grid,

Table 3.1 shows the structural diagram of the typical application system of Suntrio

Plus inverters.
