1. Introduction
GoodWe ES series inverters (hybrid) are bidirectional which apply to PV system
with battery to store energy.
Energy produced by the PV system is used to optimize self-consumption; excess
energy is used to charge the batteries, and then fed into the public grid when the
PV energy is adequate,
When PV energy output is insufficient to support connected loads, the system
automatically get energy from the batteries if battery capacity is abundant. If the
battery capacity is insufficient to meet own consumption requirements, load get
electricity from the public grid.
GoodWe ES series inverter is design for both indoor and outdoor use.

zTo avoid electric shock, DC input and AC output of the inverter must be
terminated at least 5 minutes before performing any installation or
maintenance.
zThe temperature of some parts of the inverter may exceed 60℃during
operation. To avoid being burnt, do not touch the inverter during operation.
Let it cool before touching it.
zEnsure children are kept away from inverters.
zDo not open the front cover of the inverter. Apart from performing work at
the wiring terminal (as instructed in this manual), touching or changing
components without authorization may cause injury to people, damage to
inverters and annulment of the warranty.
zStatic electricity may damage electronic components. Appropriate method
must be adopted to prevent such damage to the inverter; otherwise the
inverter may be damaged and the warranty annulled.
zEnsure the output voltage of the proposed PV array is lower than the
maximum rated input voltage of the inverter; otherwise the inverter may be
damaged and the warranty annulled.
zPV modules should have an IEC61730 classA rating. If the maximum AC
mains operating voltage is higher than the PV array maximum system
voltage, PV modules should have a maximum system voltage rating based
upon the AC mains voltage.
zIf the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
zCompletely isolate the inverter should ：Switch off the DC switch,
disconnect the PV terminal, disconnect the battery terminal, and disconnect
the AC terminal.
zCompletely isolate the inverter before maintaining. Not to enter other areas
of the inverter when maintaining!
zProhibit to insert or pull the AC and DC terminals when the inverter is
running

4. Electrical Connection
4.1 AC Output Connection
Before connecting to Grid and Load, please install a separate AC breaker
（250VAC/30A）between inverter and Grid. This will ensure the inverter can be


10

securely disconnected during maintenance.
It's very important for system safety and efficient operation to use appropriate
cable for AC connection. To reduce risk of injury, please use the proper
recommended cable size. Refer to Figure 4.1-1.
Description Size
A External diameter of the wire 10mm-12mm
B Sectional area of conducting materials 3mm -4mm
C Length of bare wire Approx.10mm

Please follow below steps to implement AC connection:
1. Check the grid voltage and frequency at the connection point of
the inverter. It should meet GoodWe product Spec.
2. Measure the impedance between neutral cable and earth cable，
make sure it is not excess than 10ohm.
3. Disconnect AC breaker between inverter and Grid.
4. Disconnect screw cap from insulator.
5. Disconnect waterproof ring from insulator.
6. Put the cable through the components in this order: screw cap,
waterproof ring, insulator, AC cover and AC terminal. Refer to
Figure 4.1-2.
7. Compress the terminal head by professional tool and screw down
screw cap slight. Refer to Figure 4.1-3、Figure 4.1-4.
8. Insert AC terminals into the corresponding holes and fasten them
by screwdriver, then fasten AC cover with pan head screws in
accessory bag. Refer to Figure 4.1-5、Figure 4.1-6 、Figure 4.1-7.
9. Screw down screw cap again.

4.2 PV Connection
zBefore connecting the PV panels, ensure the plug connectors have the correct
polarity. Incorrect polarity could permanently damage the inverter.


12

zCheck the short-circuit current of the PV string. The total short-circuit current
must not exceed the inverter’s maximum PV current.
zPV array should not be connected to the grounding conductor.
zMust be use PV plugs in accessory bag.
zThe minimum array insulation resistance to ground that system designer or
installer must meet when selecting the PV panel and system design, based on
the minimum value that the design of the PV functional grounding in the
inverter was based on. The minimum value of the total resistance 19.33kΩ
that the system must meet. There is a risk of shock hazard if the total
minimum resistance requirement is not met.
There are two types of PV plugs----sunclix series and MC4 series. Refer to
Figure 4.2-1.
