This device is directly connected to public grid, thus all work to the inveer shall only be
carried out by qualied personnel.
Danger to life due to high electrical voltage!
Notice, danger!
This is directly connected with electricity generators and public grid.
Danger of hot suace

Description
There might be residual currents in inveer because of large capacitors. Wait 5 minutes
before you remove the front lid.
The components inside the inveer will release a lot of heat during operation. Do not
touch metal plate housing during operating.
With CE mark & the inveer fullls the basic requirements of the Guideline Governing
Low-Voltage and Electro-magnetic Compatibility.
The inveer complies with the safety instructions from China's Quality Center.
Any unauthorized peorations or modications are strictly forbidden, if any defect or
damage (device/person) occurred, SAJ shall not take any responsibility for it.
DANGER
· There is possibility of dying due to electrical shock and high voltage.
· Do not touch the operating component of the inveer; 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 suace of the inveer while the housing is wet, otherwise, it might cause electrical shock.
· Do not stay close to the inveer while there are severe weather conditions including storm, lighting, etc.
· Before opening the housing, the SAJ inveer must be disconnected from the grid and PV generator; you must wait for
at least ve minutes to let the energy storage capacitors completely discharged after disconnecting from power source.
· The installation, seice, recycling and disposal of the inveers must be peormed by qualied personnel only in
compliance with national and local standards and regulations.
· Any unauthorized actions including modication of product functionality of any form may cause lethal hazard to the
operator, third paies, the units or their propey. SAJ is not responsible for the loss and these warranty claims.
· The SAJ inveer must only be operated with PV generator. Do not connect any other source of energy to the SAJ inveer.
· Be sure that the PV generator and inveer are well grounded in order to protect propeies and persons.
WARNING
· The solar inveer will become hot during operation. Please do not touch the heat sink or peripheral suace during or
sholy after operation.
· Risk of damage due to improper modications.
CAUTION
· Public utility only.
· The solar inveer is designed to feed AC power directly to the public utility power grid; do not connect AC output of the
inveer to any private AC equipment.

Please install a 4P circuit breaker to ensure the inveer is able to disconnect from grid safely.
The inveer is integrated with a RCMU, however, an external RCD is needed to protect the
system from tripping, either type A or type AC RCD is compatible with the inveer.
The integrated leakage current detector of inveer is able to detect the real time external
current leakage. When a leakage current detected exceeds the limitation the inveer will be
disconnected from grid quickly, if an external leakage current device is connected, the action
current should be 300mA or higher.

1. Follow the installation standard from previous chapter strictly to connect the photovoltaic
panels and AC power grid to inveer.
2. Using multimeter to check whether AC side and DC side voltage have met the inveer sta
voltage.
3. Turn ON DC switch (if applicable), LED indicators will be lit up.
4. Select count grid code through the APP（See Chapter 5 Monitoring Operations）, please
contact your local grid operator for which region toselect. Inveer will be in self-testing ,
if inveer has met all the grid connecting condition, inveer will connect to grid and generate
power automatically.
1. Automatically shut down, when the solar light intensity is not strong enough during sunrise
and sunset or the output voltage of photovoltaic system is less than the minimum input
power of inveer, inveer will shut down automatically.
2. Shut down manually, disconnect AC side circuit breaker rst, if multiple inveers are
connected, disconnect the minor circuit breaker prior to disconnection of main circuit
breaker. Disconnect the DC switch after inveer has repoed grid connection lost alarm.
The inveer is equipped with arc-fault circuit interrupter (AFCI). With AFCI protection, when
there is an arc signal on the DC side due to aging of the cable or loose contact, R6 series can
quickly detect and cut o the power to prevent re, making the PV system run more safely.
