3.4 Grid connection and backup load connection
·Before connecting to the grid, a separate AC breaker must be installed between the inverter
and the grid, and also between the backup load and the inverter. This will ensure the inverter
can be securely disconnected during maintenance and fully protected from over current. For
the 3/3.6/5/6KW model, the recommended AC breaker for backup load is 40A. For the3/3.6/
5/6KW model, the recommended AC breaker for grid is 40A. In final installation, breaker certified
according to AS60947.3 shall be installed with the equipment.
·There are three terminal blocks with "Grid" "Load"and "GEN" markings. Please do not misconnect
input and output connectors.

Please follow below steps to implement AC input/output connection:
1.Before making Grid, load and Gen port connection, be sure to turn off AC breakeror
disconnector first.
2.Remove insulation sleeve 10mm length, unscrew the bolts, insert the wires according to
polarities indicated on the terminal block and tighten the terminal screws. Make sure the
connection is complete.
All wiring must be performed by a qualified personnel.It is very important for
system safety and efficient operation to use appropriate cable for AC input
connection. To reduce risk of injury, please use the proper recommended cable
as below.

3.Then, insert AC output wires according to polarities indicated on the terminal block and tighten
terminal. Be sure to connect corresponding N wires and PE wires to related terminals as well.
4. Make sure the wires are securely connected.
5.Appliances such as air conditioner are required at least 2-3 minutes to restart because it is
required to have enough time to balance refrigerant gas inside of circuit. If a power shortage
occurs and recovers in short time, it will cause damage to your connected appliances. To
prevent this kind of damage, please check manufacturer of air conditioner if it is equipped with
time-delay function before installation. Otherwise, this inverter will trigger overload fault and
cut off output to protect your appliance but sometimes it still causes internal damage to the air
conditioner
3.5 PV Connection
The PV modules used to connected to this inverter shall be Class A rating certified according
to lEC 61730.
Before connecting to PV modules, please install a separately DC circuit breaker between
inverter and PV modules. It is very important for system safety and efficient operation to
use appropriate cable for PV module connection. To reduce risk of injury, please use the
proper recommended cable size as below.

3.5.1 PV Module Selection:
When selecting proper PV modules, please be sure to consider below parameters:
1)Open circuit Voltage (Voc) of PV modules not exceeds max. PV array open circuit voltage of
inverter.
2) Open circuit Voltage (Voc) of PV modules should be higher than min. start voltage.
Be sure that AC power source is disconnected before attempting to wire it to the
unit.
To avoid any malfunction, do not connect any PV modules with possible current
leakage to the inverter. For example, grounded PV modules will cause current
leakage to the inverter. When using PV modules, please ensure the PV+ & PV-
of solar panel is not connected to the system ground bar.
It is requested to use PV junction box with surge protection. Otherwise, it will
cause damage on inverter when lightning occurs on PV modules.
