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 feed
into the public grid when the PV energy is adequate,
When PV energy output is insufficient to support connected loads, the system automatically discharge energy from the batteries if
battery capacity is abundant. If the battery energy is insufficient to meet own consumption requirements, electricity will be drawn
from the public grid.
GoodWe ES series inverter is design for both indoor and outdoor use.

performing any installation or maintenance.
● The 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.
● Ensure children are kept away from inverters.
● Do 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.
● Static 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.
● Ensure 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.
● When exposed to sunlight, the PV array generates dangerous high DC voltage. Please operate according to our instructions, or it
will result in danger to life.
● PV modules should have an IEC61730 class A rating.
● If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be
impaired.
● Completely isolate the inverter before maintaining. Completely isolate the inverter should ：Switch off the DC switch, disconnect
the PV terminal, disconnect the battery terminal, and disconnect the AC terminal.
● Prohibit to insert or pull the AC and DC terminals when the inverter is running.
● In Australia, the inverter internal switching does not maintain the neutral integrity, neutral integrity must be addressed by external
connection arrangements like the example proposed in the diagram 4.10.
● In Australia, the output of backup side in switchbox should be labeled 'main switch UPS supply', the output of normal load side in
switchbox should be labeled 'main switch inverter supply'.

2.3.1 Back-Up loads
2.3.2 Back-Up Overload
Battery will act a protective charge/discharge current limitation under any condition as below:
a. Battery SOC lower than 1-DOD(Under On-Grid mode);
b. Battery voltage lower than discharge voltage
c. Ambient temperature higher than 45℃；
d.Lithium Battery communication abnormal.
When charge/discharge current limitation happens:
a.Under on-grid mode, battery charge/discharge might appears abnormal;
b.Under off-grid mode, Back-Up supply will shut off.
Note:if Back-Up supply shut off because of battery low SOC or battery voltage, then PV power will all charge battery till
battery SOC reaches 40%+(1-DOD)/2, when Back-Up supply will be waken again.
2.3.3 Battery protection
d. For lead-acid batteries connecting with GoodWe Hybrid inverter, the SOC is calculated on inverter side. As lead-acid battery
has various brands and battery cycling life, the SOC calculation will has deviation from the real SOC.
e. For lead-acid battery band, the SOC calculated is the total SOC of the whole bank, thus if there is any uniformity deviation
between different battery cells, which will cause overcharge or over-discharge on some cells, further will damage the cell(s)
and shorten battery bank life.
f. For lead-acid batteries, please honestly refer to your battery specifications to set Battery Capacity, Charge/discharge
current, Charge Voltage and Discharge Depth etc. Default Discharge Voltage is 42V (non-editable). Unsuitable settings for
lead-acid batteries will possiblly lead to inaccurate battery SOC, weak battery lifespain, or further battery damage.
g. For damage caused by unsitable settings, battery out of warranty, battery quality etc, it is ivnerter-irresponsible.
For details, please refer to battery user manual.
2.3.4 Lead-Acid Batteries Used in Hybrid system
2.3.5 Statement on Wiring Connection in SPLIT Grid System

8 Work Modes
ES series inverters have the following main work modes based on different conditions:
Mode1：
Energy produced by the PV system priority for local load,
excess energy is used to charge the battery, finally
remaining is delivered to the grid.
Mode2：
If there is no PV, battery energy is used for local load
first, the grid also can supply when the battery capacity
is not enough.
Mode3：
If the grid is fault or there is no grid, the system can still
work, PV and batteries supply energy for local load.
Mode4：
The battery can be charged by the grid, time and power
of battery charging can be set up flexibly.

[1] For lead-acid battery, default charge current is 0.15C, which is can be configurable up to 0.5C by APP EzManage and cannot
exceed the maximum current. C means the battery capacity, such as the battery capacity is 100Ah, default charge current 0.15C
is 0.15 * 100A = 15A. For Li-Ion battery, discharge and charge current follows the command of BMS which doesn't exceed the
maximum current.
[2]Under off-grid mode, then battery capacity should be more than 100Ah.
[3]When there is no battery connected, inverter starts feeding in only if string voltage is higher than 200V.

Note
Overvoltage category definition
Category I : applies to equipment connected to a circuit where measures have been taken to reduce transient overvoltage to a
low level.
Category II : applies to equipment not permanently connected to the installation. Examples are appliances, portable tools and
other plug-connected equipment;
Category III: applies to fixed equipment downstream of and including, the main distribution board. Examples are switchgear
and other equipment in an industrial installation;
Category IV: applies to equipment permanently connected at the origin of an installation (upstream of the main distribution
board). Example are electricity meters, primary overcurrent protection equipment and other equipment connected
directly to outdoor open lines.
Environment category definition
Outdoor : the ambient air temperature is -20~50°C, Relative humidity range is 4 % to 100 %, applied to PD3
Indoor unconditioned: the ambient air temperature is -20~50°C, Relative humidity range is 5 % to 95%,applied to PD3
Indoor conditioned: the ambient air temperature is 0~40°C, Relative humidity range is 5 % to 85%,applied to PD2
Pollution degree definition
Pollution degree 1: No pollution or only dry, non-conductive pollution occurs. The pollution has no influence.
Pollution degree 2: Normally only non-conductive pollution occurs. Occasionally, however, a temporary conductivity caused by
condensation must be expected.
Pollution degree 3: Conductive pollution occurs, or, dry, non-conductive pollution occurs which becomes conductive due to
condensation which is expected.
Pollution degree 4: Persistent conductive pollution occurs, for example, the pollution cause by conductive dust, rain and snow.
