Note:
The introduction describes a general working situation of ES system.
The operation mode can be adjusted on GoodWe PV Master APP
up to the system layout. The general operation modes for ES system
are as below:
01 INTRODUCTION
GoodWe ES series, also called hybird or bidirectional solar inverters, apply to soalr system with
partcipation of PV, battery, loads and grid system for energy management.
The energy produced by PV system shall be used to optimize household, excess power charges
battery and the rest power could be exported to the grid.
Battery shall discharge to support loads when PV power is insufficient to meet self-consumption
needs. If battery power is not sufficient, the system will take from grid to support load.
The energy produced by the PV system is used to
optimize self-consumption. The excess energy is used to
recharge the batteries, the rest is exported to grid.
When grid fails, the system automatically switches to
Back-Up mode. The Back-Up load can be supported by
PV and battery.
Battery could be charged by grid, and charge time/power
could be set on PV Master APP.
When there is no PV, and the battery is sufficient, it can
supply the load together with grid power.
ES system normally has the following operation modes based on your configuration and layout
conditions.
Mode Ⅰ Mode Ⅱ
Mode Ⅲ Mode Ⅳ

Safety Warning
Any installation and operation on inverter must be performed by qualified electricians, in compli-
ance 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 battery 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 operation, so please make
sure it has cooled down before touching it, and make sure the inverter is out of reach of
children.
Do not open the inverter's cover or change any components without manufacturer's autho-
rization, otherwise the warranty commitment for the inverter will be invalid.
Usage and operation of the inverter must follow instructions in this user manual, otherwise
the protection design might be impared and 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 manufacturer.
PV negative (PV-) and battery negative (BAT-) on inverter side is not grounded as default
design. Connecting PV- to EARTH are strictly forbidden.
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.
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, the inverter internal switching does not maintain neutral integrity, which must
be addressed by external connection arrangements like in the system connection diagram
for Australia on page 16.
In Australia, output of back-up side in switchbox should be labeled on "Main Switch UPS
Supply".The output of normal load side in switch box should be labeled "Main Switch Invert-
er Supply".

Battery Protection
Battery will act as a protective charge/discharge current limitation under any condition as below:
• Battery SOC is lower than I-DOD (Depth of discharge).
• Battery voltage is lower than discharge voltage.
• Battery over heating protection.
• Battery communication is abnormal for lithium battery.
• BMS limitation for lithium battery.
When charge/discharge current limitation protection happens:
• Under on-grid mode, battery charge/discharge operation could be abnormal.
• Under off-grid mode, Back-Up supply will shutdown.
Note:
• Under off-grid mode, if Back-Up supply shuts off because of battery, 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.
• Under on-grid mode & off-grid mode, battery is protected from over discharge by DOD and discharge voltage.
• 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 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 from falling to 0% SOC.
2.4.3 On-Grid & Back-Up Connection
An external AC breaker is needed for on-grid connection to isolate from grid when necessary.
The requirements of on-grid AC breaker are shown below.
Note:
1. Neutral cable shall be blue, line cable shall be black or brown (preferred) and protective earth cable shall
be yellow-green.
2. For AC cables, PE cable shall be longer than N&L cables, so in case that the AC cable slips or is taken
out, the protecting earth conductor will be the last to take the strain.
Make sure the inverter is totally isolated from any DC or AC power before connecting AC
cable.
AC cable is required to connect to both on-grid and back-up side.
1. Use separated AC breaker for individual
inverter.
2. On the AC side, the individual breaker
should be connected between inverter
and Grid but before loads.

Declaration For Back-Up Function
The back-up output of ES hybrid inverters have over load ability.
For details please refer to the technical parameters of ES series inverter section (Page 31).
And the inverter has self-protection derating at high ambient temperature.
The below statement lays out general policies governing the energy storage inverters of the series
EH, EM, ES, ET, BH, BT and SBP.
1. For Hybrid inverters (Series EH, EM, ES and ET), the standard PV installation typically consists of
the connection of the inverter with both panels and batteries. In the case where the system is
not connected to the batteries, the back-up function is strongly not advised for use. Manufactur-
er shall not cover the standard warranty and be liable for any consequences arising from users
not following this instruction.
2. Under normal circumstances, the back-up switching time is less than 10 ms (the minimal
condition to be considered as the UPS level). However, some external factors may cause the
system failing on back-up mode. As such, we recommend the users to be aware of conditions
and follow the instructions as below:
• Do not connect loads when they are dependent on a stable energy supply for a reliable opera-
tion.
• Do not connect the loads which may in total exceed the maximum back-up capacity.
• Try to avoid those loads which may create very high start-up current surges such as inverter
air-conditioner, high-power pump etc.
• Due to the condition of the battery itself, battery current might be limited by some factors
including but not limited to the temperature, weather etc.
Accepted Loads As Below:
ES series inverter is able to supply a continuous 4600VA output or maintain a 6900VA output for
less than 10 seconds on back-up side to support loads. The inverter also has self-protection
against derating at high ambient temperature.
• Inductive Load: Maximum 1.5KVA for single inductive load, maximum 2.5KVA for total inductive
load power.
• Capacitive Load: Total capacitive load (like computer, switch power etc.)power ≤3.0KVA.
(Any load with high inrush current at start-up is not accepted)
Note:
For convenient maintenance, please install a SP3T switch on back-up and on-grid side. Then it is adjustable
to support load by back-up or by grid or default settings.
1. Back-up load is supplied from back-up side.
2. Back-up load is isolated.
3. Back-up load is supplied from grid side.

occurs.
04 OTHERS
ERROR MESSAGE EXPLANATION REASON SOLUTIONS
Check (use multi-meter) if there is voltage (normally should be close to 0V) between earth & inverter frame. If there is a voltage, it means the neutral &
ground cables are not connected well on the AC side. If it happens only in the early morning/dawn /rainy days with higher air humidity and is recovered
soon, it should be normal.
Check (use multi-meter) if there is high voltage (normally should be lower than 10V) between N & PE cable on the AC side. If the voltage is higher than
10V, it means the Neutral & ground cable are not connected well on AC side or restart inverter.
1. Check (use multi-meter) if AC side has voltage . Make sure grid power is available.
2. Make sure AC cables are connected tightly and well.
3. If all is well, please try to turn off AC breaker and turn on again in 5 mins.
1. Make sure safety country of the inverter is set right.
2. Check (use multi-meter) if the AC voltage (Between L & N) is within a normal range (also on AC breaker side)
a. If the AC voltage is high, then make sure the AC cable complies with that required on user manual and the AC cable is not too long.
b. If the voltage is low, make sure the AC cable is connected well and the jacket of the AC cable is not compressed into the AC terminal.
3. Make sure the grid voltage of your area is stable and within normal range.
1. Make sure the safety country of the inverter is set right.
2. If safety country is right, then please check on the inverter display if AC frequency (Fac) is within a normal range.
3. If FAC failure only appears a few times and is resolved soon, it should be caused by occasional grid frequency unstability.
1. Try to decrease surrounding temperature.
2. Make sure the installation complies with the instruction on inverter user manual.
3. Try to close the inverter for 15 mins, then start up again.
1. Use multi-meter to check if the resistance between earth & inverter frame is close to zero. If it's not, please ensure that the connection is well.
2. If the humidity is too high, isolation failure may occur.
3. Check the resistance betwen PV1+/PV2+/BAT+/PV- to earth.If the resistance is lower than 33.3k, check the system wiring connection.
4. Try to restart the inverter.Check if the fault still occurs. If not, it means it is caused by an occasional situation, or contact after-sales.
Try to restart the inverter,check if it still occurs.If not,it is just an occasional situation.Otherwise, contact after-sales immediately.

ES does not start up with battery only
Solution:
Make sure the voltage of battery is higher than 48V, otherwise battery cannot start ES up.
ES not started up with PV only
Solution：
1. Make sure the voltage of PV is highter than 150V（need 200V to enter on-grid mode ）.
2. Make sure the connection between ES and PV panels：polarities are （+/-）not reversed.
ES hybrid inverter doesn't discharge or output without PV or when PV is lower than load
power
Solution:
1. Check communication between ES and Smart Meter 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 does not discharge when Meter power is higher than 150W, please check Smart
Meter & CT connection and direction;
3. Make sure SOC (State of discharge) is higher than 1-DOD (Depth of discharge). Or if battery
discharges to below 1-DOD, battery will only discharge again when SOC charged to（20%+1-DOD
）/ 2 and SOC＞105% -DOD (if the battery discharge is needed immediately, the user should
restart battery).
4. Check on APP whether whether the charge time has already been set, as during charge time,
battery will not discharge (Battery will charge in priority during coincident time of charge/dis-
charge).
Battery does not charge when PV power higher than load power
Solution：
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 the discharge time setting on App.
3. Check if battery is fully charged or not, or if battery voltage reaches "charge voltage" or not.
High power fluctuation on battery charge or discharge
Solution：
1. Check if there is a fluctuation on load power.
2. Check if there is a fluctuation on PV power.
Problems During Operation
• Battery Connection: Confirm the connection between ES and battery : polarities (+/-) are not
reversed, refer to figure 4.2-1
• PV Input Connection: Confirm the connection between ES and PV panels: polarities (+/-) are
not reversed, refer to figure 4.2-2.
• On-Grid & Back-Up Connection: Confirm on-grid connected to power grid and back-up
contected to loads: polarities (L/N are in sequence) are not reversed, refer to figure 4.2-3.
• Smart Meter & CT Connection: Make sure Smart Meter & CT are connected between house
loads and grid, and follow the Smart Meter direction sign on CT, refer to figure 4.2-4.

Questions & Answers (Q & A)
About Wi-Fi Configuration
Q: Why can't I find the Solar-WiFi* signal on mobile devices?
A: Normally Solar-WiFi* signal could be searched right after inverter has powered up. But Solar-Wi-
Fi signal will disappear when ES connects to internet. If changes to the setting are required,
connect to the router for change. If you can't find the WiFi signal or connect to the router, then
please try to reload Wi-Fi (please refer to ES user manual page 18).
Q: Why can't I connect Solar-WiFi* signal on my phone?
A: The Wifi module can only connect to one device at a time. If the signal is already connected to
another device at the time for some reason, you cannot connect to the signal.
Q: Why does the Wi-Fi module fail to connect to network after I choose the right router
hotspot and enter the right passwords?
A: It's possible that there are special characters not supported by module in the hotspot
passwords. Please modify the password to consist of only Arabic numerals or uppercase
/lowercase letters.
About Battery Operation
Q: Why does the battery not discharge when grid is not available, while it discharges
normally when grid is available?
A: On the App, off-grid output and back-up function should be turned on to make battery
discharge under off-grid mode.
Q: Why is there no output on back-up side?
A: For back-up supply, the "Back-Up Supply" on PV Master App must be turned on. Under off-grid
mode or when grid power is disconnected, "Off-Grid Output Switch" function must be turned on
as well.
Note: When turning "Off-Grid Output Switch" on, don't restart inverter or battery, otherwise the function will be switched
off automatically.
Battery does not charge:
Solution:
1. Make sure BMS communication is OK on PV Master (for lithium batteries).
2. Check if CT is connected in the right position and direction as on the user manual page 15.
3. Check if the total load power is much higher than PV power.
Q: Why does the battery SOC suddenly jump to 95% on the Portal?
A: It normally happens when BMS communication fails on lithium battery. If battery enters float
charge mode, SOC will be reset to 95% automatically.
Q: The battery cannot be fully charged to 100%?
A: Battery will stop charging when battery voltage reaches charge voltage set on PV Master App.
Q: Why battery switch always trip when it starts up (lithium battery)?
A: The switch of lithium battery normally trips because of following reasons:
1. BMS communication fails.
2. Battery SOC is too low, battery trips to protect itself.
3. An electrical short-cut happened on battery connection side. Or for other reasons please
contact after-sales.
Q: Which battery should I use for ES?
A: For ES series inverter, it could connect lithium batteries which have compatibility with ES series
inverter with nominal voltage 48V. For compatible lithium batteries please refer to battery list in
PV Master App.
About PV Master Operation And Monitoring
Q: Why can't I save settings on PV Master App?
A: It could be caused by losing connection to Solar-WiFi *.
1. Make sure you have already connected Solar-WiFi* (make sure no other devices connected) or
router (if connected Solar-WiFi* to router). APP's homepage shows connection well.
2. Make sure you restart inverter 10mins after you change some settings because inverter will
save settings every 10 mins under normal mode. We recommend to change setting parame-
ters when inverter is in wait mode.
Q: Why are the data displayed on the homepage different from the param page, like
charge/discharge, PV value, load value or grid value?
A: The data refresh frequency is different, so there will be a data inconformity between different
pages on the App as well as between these on portal and App.
Q: Some columns show NA, like battery SOH, etc. Why does that happen?
A: NA means App does not receive data from inverter or server because of communication
problem, such as battery communication, and communication between inverter and the App.

About Smart Meter And Power Limit Function
Q: How to activate output power limit function?
A: For ES system, the function could be realized by:
1. Make sure Smart Meter connection and communication well.
2. Turn on export power limit function and set the max output power to grid on App.
Note: Even if output power limit is set to 0W, there might still be a deviation of a max of 100W exporting
to grid.
Q: Why is there still power exporting to grid after I set power limit as 0W?
A: Export limit could be 0W theoretically, but there will be a deviation of around 50-100W for ES
system.
Q: Can I use other brand meter to take over Smart Meter in ES system or change some
settings on Smart Meter?
A: No, because the communication protocol is integrated into inverter and Smart Meter, other
brand meters cannot communicate. Also any manual setting change could cause Meter
communication failure.
Q: What is the maximum current allowed to go through CT on Smart Meter?
A: The max current for CT is 120A.
Other Questions
Q: Is there a quick way to make the system work?
A: For the shortest way, please refer to "ES Quick Installation Instructions" and "PV Master App
Instruction".
Q: What kind of load can I use to connect on back-up side?
A: Please refer to user manual on page 12.
Q: Will the warranty of the inverter still be valid if for some special conditions we cannot
100% follow the user manual instructions on the installation or operation?
A: Normally we still provide technical support to problems caused from disobeying the instruc-
tions on the user manual, however we cannot guarantee any replacements or returns. So if
there is any special conditions where you cannot 100% follow the instructions, please contact
after-sales for suggestions.

Appendix Protection Category Defintion
Overvoltage category definition
Category I
Category II
Category III
Category IV
Applies to equipment connected to a circuit where measures have been
taken to reduce transient overvoltage to a low level.
Applies to equipment not permanently connected to the installation.
Examples are appliances, portables tools and other plug-connected
equipment.
Applies to a fixed equipment downstream and including the main
distribution board. Examples are switchgear and other euiquipment in an
industrial installation.
Applies to equipment permanently connected at the origin of an installa-
tion (upstream of the main distribution board). Examples are electricity
meters, primary over-current protection equipment and other equipment
connected directly to outdoor open lines.

No pollution or only dry, non-conductive polllution occurs.
The pollution has no influence.
Normally only non-conductive pollution occurs. Occasionally,
however, a temporary conductivity caused by condensation
must be expected.
Conductive pollution occurs, or dry. non-conductive pollution
occurs, which becomes conductive due to condensation,
which is expected.
Persistent conductive pollution occurs, for example, the
pollution caused by conductive dust, rain or snow.
