INTRODUCTION INTRODUCTION
• SAFETY WARNING 1.3 PRODUCT OVERVIEW
Any installation and operation on inverter must be performed by qualified electricians, in compliance
with standards, wiring rules or requirements of local grid authorities or companies (like AS 4777 and
AS/NZS 3000 in Australia).
Before any wiring connection or electrical operation on inverter, all DC and AC power must be
disconnected from inverter for at least 5 minutes to make sure inverter is totally isolated to
avoid electric shock.
The temperature of inverter surface might exceed 60℃during working, so please make sure it
is cooled down before touching it, and make sure the inverter is untouchable for children.
Usage and operation of the inverter must follow instructions in this user manual, otherwise the
protection design might be useless and warranty for the inverter will be invalid.
PV negative (PV-) on inverter side is not grounded as default design.
The inverter, with built-in RCMU, will exclude possibility of DC residual current to 6mA, thus in
the system an external RCD (type A) can be used(≥30mA).
IN Australia, output of Back-Up side in switchbox should be labeled ‘Main Switch UPS supply’,
the output of normal load side in switch box should be labeled ‘Main Switch Inverter Supply’.
Do not open inverter cover or change any components without GoodWe’s authorization,
otherwise the warranty commitment for the inverter will be invalid.
Appropriate methods must be adopted to protect inverter from static damage. Any damage
caused by static is not warranted by GoodWe.
PV modules used on the inverter must have an IEC61730 class A rating, and the total
open-circuit voltage of PV string/array is lower than the maximum rated DC input voltage of the
inverter. Any damage caused by PV over-voltage is beyond warranty.
In Australia, the inverter internal switching does not maintain neutral integrity, which must be
addressed by external connection arrangements like in the Off-Grid System Connection
Diagram in page 16.

Battery wiring connection steps as below:
• Please be careful against any electric shock or chemical hazard
• For lithium battery (pack) the capacity should be 50Ah or larger. Lead acid batteries are not allowed
to use with GoodWe hybrid inverters without GoodWe's authority. Battery cable requirement as
below. (Pic 11)
• Make sure there is an external DC switch (≥125A) connected for battery without build-in DC
switch
2.4.2 BATTERY CONNECTION
Make sure battery switch is off and battery nominal voltage meet ES specification before
connecting battery to inverter and make sure inverter is totally isolated from PV and AC power.[4]
NOTE:
1. Please use accessories from GoodWe box
2. Battery power cable should be 20-25 mm²
NOTE: Please make sure polarity (+/-) of
battery are not reversed
Prepare battery cables and accessories and put
battery power cable through battery cover (Pic 12 )
Step 2
Make battery terminals (Pic 13)

• FOR LEAD-ACID BATTERIES
NOTE:
• Under off-grid mode, if Back-Up supply shuts off because of battery of low battery SOC or voltage, PV
power will all be used to charge battery till battery SOC reaches 40% + (1-DOD)/2, then Back-Up supply
will be activated up.
• Under on-grid mode , battery is protected from over discharge by DOD and discharge voltage, under
off-grid mode , it is protected by only discharge voltage and DOD.
• The DOD setting of a battery prevents the inverter from discharging battery reserve power. As soon as
the DOD is reached the load of building will only be supported by either PV power or from the grid. If there
are continuous days when little or no battery charging occurs, the battery may continue to self-consume
energy to support communications with the inverter. This behaviour is different between battery
manufactures products, however, if the SOC of the battery reaches a certain level the inverter will boost the
SOC back up. This protection mechanism safeguards the battery to falling to 0% SOC.
* For the compatible lithium batteries (LG/Pylon/BYD/GCL) connection, please refer to battery
connection part in ES QUICK INSTALLATION INSTRUCTIONS.

Battery will act a protective charge/discharge current limitation under any condition as below:
When charge/discharge current limitation protection happens:
For lead-acid batteries, battery SOC calculation might not be so accurate result from like
battery inconformity between cells, battery aging or other specifications of lead-acid battery etc.
For lead-acid battery bank, the inconformity between battery cells might lead to battery cell
over-charge or discharge, and further might damage battery cells and shorten battery bank life
For lead-acid battery settings on PV Master App, please honestly refer to battery specifications
and the actually battery work condition like work temperature and battery age. Unsuitable
settings will lead to higher SOC deviation, weaker battery lifespan and further battery damage.
GoodWe will keep the right for explanation on all the settings suggested and all the problems
happened on lead-acid batteries or the whole system. And GoodWe is not responsible for any
damage caused by unsuitable settings, battery beyond warranty or battery quality etc.
For ES series inverters there is no temperature compensation, thus customers need do battery
settings based on the real working temperature of battery.
Lead-Acid and other similar older-technology battery types require experienced and precise
design, installation and maintenance to work effectively. For details, please refer to Approved
Battery Option Statement (download from www.goodwe.com)
• BATTERY PROTECTION DESCRIPTION
• Under on-grid mode, battery charge/discharge operation could be abnormal
• Under off-grid mode, Back-Up supply will shut down
• Battery SOC is lower than 1-DOD
• Battery voltage lower than discharge voltage
• Battery communication abnormal for lithium battery
• BMS limitation for lithium battery

The error massages below will be displayed on PV Master App or report by Email if the error really happen.
Note: All the errors about battery happen only on lithium battery with BMS communication.
• ERROR MASSAGE
Utility Loss
VAC Failure
Not available of public grid power (power loss or
on-grid connection fails)
Grid voltage is not within permissible range
Inverter does not detect the connection of grid
Inverter detects that AC voltage is beyond the normal
range required by the safety country
FAC Failure Grid Efficiency is not within permissible range Inverter detects that Grid frequency is beyond the normal
range required by the safety country
1. Make sure safety country of the inverter is set right
2. If safety country is right, then please check on inverter display if AC frequency (Fac) is within a normal range
3. If FAC failure only appear a few times and resolved soon, it should be caused by occasional grid frequency unstability.
PV Over Voltage DC total voltage of PV string is too high The total voltage (short-circuit voltage) of each PV string is
higher than the max DC input voltage of the inverter.
Check PV string VOC is lower than Max PV Input Voltage of the inverter
If VOC of PV string is high, please decrease panels to make sure VOC is with the max DC input voltage of the inverter.
Over Temperature Temperature inside of the inverter is too high Inverter working environment leads to a high temperature condition
1. Try to decrease surrounding temperature
2. Make sure the installation complies with the instruction on inverter user manual
3. Try to close inverter for 15 mins, then start up again.
Isolation Failure Ground insulation impedance of PV string is too low
Isolation failure could be caused by multi reasons like PV panels are
not grounded well, DC cable is broken, PV panels are aged or
surrounding humility is comparatively heavy, etc.
1. Try to decrease surrounding temperature
2. Make sure the installation complies with the instruction on inverter user manual
3. Try to close inverter for 15 mins, then start up again.
Ground I Failure Ground leakage current is over-high
Ground I failure could be caused by multi reasons like neutral cable
on AC side is not connected well or surrounding humility is
comparatively heavy, etc.
Check use multi-meter if there is voltage value (normally should be close to 0V) between earth & inverter frame.
If there is a voltage, it means the Neutral & ground cable are not connected well on AC side. If it happened only
at early morning, dawn or on rainy days with high air humidity, and recover soon, it should be normal
Relay Check Failure Self checking of relay fails Neutral & ground cable are not connected well on AC side or just
occasional failure
Check use multi-meter if there is high voltage (normally should be lower than 10V) between N&PE cable on AC side.
If the voltage higher than 10V, it means the Neutral & ground cable are not connected well on AC side or restart inverter.
DC Injection High /Inverter detects a higher DC component in AC output Try to restart inverter, check if it still happens, if not, means it is just an occasional situation or contact GoodWe
EEPROM R/W Failure /Caused by a strong external magnetic field etc. Try to restart inverter, check if it still happens, if not, means it is just an occasional situation or contact GoodWe
SPI Failure Internal communication fails Caused by a strong external magnetic field etc. Try to restart inverter, check if it still happens, if not, means it is just an occasional situation or contact GoodWe
DC Bus High BUS voltage is over-high /Try to restart inverter, check if it still happens, if not, means it is just an occasional situation or contact GoodWe
Back-Up Over Load Back-up side is over loaded Total Back-Up load power is higher than the nominal backup
output power
Decrease Back-Up loads to make sure the total load power is lower than Back-Up nominal output power (please
refer to page 12)

Problems During Operation
1. Make sure the voltage of battery is higher than 48V, otherwise battery cannot start ES up.
Solution:
ES not Start Up With ONLY Battery
1.Make sure the voltage of PV is higher than 150V (need 200V to enter on-grid mode).
2.Make sure that connection between ES and PV panels : polarities ( +/-) not reversed.
Solution:
ES not Start Up With ONLY PV
1.Communication between ES and EzMeter is OK or not
2.Make sure load power is higher than 150W
a.battery will not discharge continuously unless load power is higher than 150W
b.If battery still not discharge when Meter power is higher than 150W, then please check EzMeter &
CT connection and direction
3.Make sure SOC is higher than 1-DOD. Or if battery discharged to below 1-DOD, than battery will
only discharge again when SOC charged to 20%+（1-DOD）/ 2 and SOC ＞105% -DOD (if need
battery discharge immediately, battery should be restarted)
4.Check on APP if already set charge time, as during charge time, battery will not discharge (battery will
charge in priority during coincident time of charge/discharge)
Solution:
No Discharge or Output From ES at Night Without PV or PV Power Lower Than Load Power:
1.Check if charge voltage on App (in “Param” ) is properly set (for lead-acid battery) as battery cannot
charge if battery voltage reaches charge voltage
2.Check if it is during discharge time set on App
3.Check if battery is fully charged or not, or battery voltage reach “charge voltage” or not
Solution:
Battery Not Charge When PV Power Higher Than Load Power:
1.Check if there is a fluctuation on load power
2.Check if there is a fluctuation on PV power
Solution:
High Power Fluctuation on Battery Charge or Discharge:
1.Make sure BMS communication is OK on PV Master (for lithium batteries)
2.Check if CT connected in the right position and to right direction as on the user manual page 13
3.Check if the total load power is much higher than PV power
Solution:
Battery Does Not Charge

Other Questions
Questions & Answers (Q & A)
About Wi-Fi Configuration
A: Normally Solar-WiFi signal could be searched right after inverter powered up. But Solar-WiFi signal
will disappear when ES connected to internet. If need change settings, can connect to the router to
change. If cannot see WiFi signal even not connect to router, then please try to reload WiFi (please
refer to ES user manual page 18)
Q: Why cannot see Solar-WiFi signal on mobile devices
A: It is the character of the Wi-Fi module that it can connect to only one device at a time. If the signal is
connected to another device at the time for some reason, then you cannot connect to the signal.
Q: Why cannot connect Solar-Wifi signal on my phone?
A: For Back-Up supply, the “Back-Up Function” on PV Master App must be turned on. Under off-grid
mode or grid power is disconnected, “Off-Grid Out” function must be turned on as well
Note: As turn “Off-Grid Output” on, don’t restart inverter or battery, otherwise the function will switch off
automatically.
Q: Why there is output on Back-Up side?
A: This normally happens on lead-acid batteries or when BMS communication fail on lithium battery. If
battery enter float charge, SOC will be reset to 95% compulsively.
Q: On Portal, why battery SOC has a sudden jump up to 95%?
A: For LG battery, it will stop charge at SOC 95%. It is normal about LG battery. And also battery will
stop charge when battery voltage reaches charge voltage set on PV Master APP
Q: Why battery cannot be fully charged to 100%
A: For lithium battery like LG, normally the switch trips for flowing reason:
1.BMS communication fails, or battery SOC is so low to protect itself.
2.Battery SOC is too low, battery trips to protect itself.
3.An electrical short-cut happened on battery connection side. Or other reasons please contact
GoodWe for details.
Q: Why battery switch always trip when starts it up (Lithium battery)?
A: For EM inverters, it could connect lithium or lead-acid batteries, with nominal voltage 48V, max
charge voltage 60V
Compatible lithium batteries for now: LG RESU3.3/6.5/10, BYD B-Box 2.5/5.0/7.5/10,
GCL5.6KWh, Pylon US2000B (1~4 packs). For lead-acid batteries: please contact GoodWe to
confirm if it is suitable to use.
Q: Which battery should I use for EM?
2.Make sure EM under waiting mode (on APP) before you change any settings on PV Master APP ---
disconnect grid/load/battery, only leave PV connected and then restart EM till see work mode as “wait”
on APP.
A: This could be caused by losing connection to Solar-WiFi.
1.Make sure you connected Solar-WiFi (make sure no other devices connected) or router (if
connected Solar-WiFi to router) and on APP home page shows connection well.
Q: Why Cannot save settings on PV Master App
A: As the data on APP is from inverter and on home page and Param page, the data refresh frequency
is different, so there will be a data inconformity between different pages on APP as well as between
that on portal and APP
Q: On the App, why the data on the homepage and Param page is different, like charge/discharge,
PV value, load value or grid value?
A: NA means App does not receive data from inverter or server, normally it is because
communication problem, such as battery communication, and communication between inverter and
the APP.
Q: On App, some columns show NA, like battery SOH, etc. why is that?
A: Export limit could theoretically to minimum 0W, but there will have a deviation of around 50-100W
for ES system.
Q: Why there is still power exporting to grid after I set power limit as 0W?
A: Cannot, because there the communication protocol is inset between inverter and EzMeter, other
brand Meter cannot communicate. Also any manual setting change could cause EzMeter
communication failure.
Q: Can I use other brand Meter to take over EzMeter in EM system or change some settings on
EzMeter?
A: The max current for CT is 120A
Q: What is the max current allowed going through CT on EzMeter?
A: The shortest way, please refer to QUICK INSTALLATION INSTRUCTIONS and PV MASTER
APP INSTRUCTION
Q: Is there a quick way to make the system work?
A: Please refer to user manual on page 12
Q: What kind of load can I connect on Back-Up side?
A: Normally if any problem caused by disobey the instructions on user manual, we can provide
technical support to help solve the problem, but cannot guarantee a replacement or returns. So if
there is any special condition when you cannot 100% follow the instructions, please contact GoodWe
for suggestions.
Q: Whether the warranty of the inverter still valid if the installation or operation does not follow
the user manual instructions, for some special conditions when we cannot 100% follow them?
A: On APP, Off-Grid Output and backup function should be turned on to make battery discharge
under off-grid mode.
Q: Why battery does not discharge when grid is not available, while it discharge normally when
grid is available?
A: For EM system, the function could be realized by:
1. Make sure EzMeter connection and communication well
2. Turn on Export Power Limit function and Set the max output power to grid on APP
Q: How to Act Output Power Limit function?
Note: If Out-put Power Limit set as 0W, then there might still have deviation max 100W exporting to grid.
