TABLE OF CONTENTS

GoodWe EM series, also called hybrid or bidirecational solar inverters, apply to solar system with participation of
PV, battery, loads and grid system for energy management.
The energy produced by PV system shall be used to optimize self-consumption, excess power charge battery and
the rest power could be exported to the grids.
Battery shall discharge to support loads when PV power is insufficient to meet self-consumption. If both PV power
and battery power is insufficient, the system will take power form grid to support loads.
Note: The introduction describes a general behavior of EM
system. The operation mode can be adjusted on GoodWe SolarGo
APP based on the system layout. Below are the general operation
based on the system layout. Below are the general operation
modes for EH system.
INTRODUCTION01
EM system normally has the following operation modes based on your configuration and layout conditions.
1.1 OPERATION MODES INTRODUCTION
The energy produced by the PV system is
used to optimize self-consumption. The
excess energy is used to charge the
batteries, then exported to gird.
When there is no PV, and the battery is
sufficient , It can supply the load with the
grid power.
When grid fails , the system automatically
switches to Back-Up mode, the Back-Up
load could be supported by PV and battery.
Battery could be charged by grid, and
charge time/power could be set flexibly on
SolarGo APP.

· SAFETY WARNING
· Prohibit to insert or pull the AC and DC terminals when the inverter is running.
· 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 working, so please make sure it is cooled
down before touching it, and make sure the inverter is untouchable for children.
· Do not open inverter cover or change any components without GoodWe’s authorization, 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 useless and warranty 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 negative (PV-) and battery negative (BAT-) on inverter side is not grounded as default design. Connect-
ing PV- or BAT- 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 ‘Main switch UPS supply’, the
output of normal load side in switch box should be labeled ‘main switch inverter supply’.
Any installation and operation on hybrid 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).

* For the compatible lithium batteries (LG/Pylon/BYD/GCL) connection, please refer to battery connection part
in EM QUICK INSTALLATION INSTRUCTIONS.
Make battery terminals
• Strip cable coat, revealing 10mm length of metal core
• Use special crimper to compress battery terminal tightly
Note：
• Please use accessories from GoodWe box
• Battery power cable should be 20~25mm2
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% + (I-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 in priority.
• 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 safegurads the battery to falling to 0% SOC.
Note：Please make sure polarity (+/-) of
battery are not reversed

Connection for SPLIT Grid System
In SPLIT grid system, there is a solution to
allow inverter work under on-grid condition
(Figure 2.4.3-1). For details, please check the
official application plan on website -GoodWe
Hybrid Solution For Split Grid Type.
Declaration For Back-Up Function
The below statement lays out GoodWe general policies governing the energy storage inverters of the series ES,
EM, SBP, ET, EH and BH.
• For Hybrid inverters (Series ES, EM, EH and ET), the standard PV installation typically consists of the connection
of the inverter with both panels and batteries. In case of systems not connected to the batteries, the Back-Up
function is strongly not advised to use. GoodWe shall not cover the standard warranty and be liable for any
consequences arising from users not following this instruction.
• 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 to fail on Back-Up mode. As
such, we recommend the users to be aware of conditions and follow the instructions as below:
1. Do not connect loads if they are dependent on a stable energy supply for a reliable operation.
2. Do not connect the loads which may in total exceed the maximum Back-Up capacity.
3. Try to avoid those loads which may create very high start-up current surges such as Inverter Air-conditioner,
high-power pump etc.
4. Due to the condition of battery itself, battery current might be limited by some factors including but not
limited to the temperature, weather etc.
Note：If you don't use the back-up function or use on-grid power to charge the battery,the wiring
conduct core section can use 4-6mm

4.2 ERROR MESSAGE AND TROUBLESHOOTINGS
ERROR MASSAGE EXPLANATION REASON SOLUTIONS
Check use multi-meter if there is voltage (normally should be close to 0V) between earth & inverter frame.
If the 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 higher air humidity, and recover 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 AC side.
If the voltage 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 right well.
3. If all is well, please try to turn off AC breaker and turn on again after 5 mins.
1. Make sure safety country of the inverter is set right.
2. Check (use multi-meter) if AC voltage (Between L & N) is within a normal range (Also on AC breaker side)
a. if AC voltage is high, then make sure AC cable complies with that required on user manual and AC cable is not too long
b. if voltage is low, make sure AC cable is connected well and the jacket of AC cable is not compressed into AC terminal
3. Make sure the grid voltage of your area is stable and within normal range.
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.
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.
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.

EM not start up with only battery
Solution:
Make sure the voltage of battery is higher than 180V, otherwise battery cannot start BT up.
EM not start up with only PV
Solution:
1. Make sure the voltage of PV is higher than 150V (need 200V to enter on-grid mode);
2. Make sure that connection between EM and PV panels: polarities (+/-) not reversed.
No discharge or output from EM at night without PV or PV power lower than load power:
Solution:
1. Communication between EM and SmartMeter 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 SmartMeter & CT
connection and direction;
3. Make sure SOC is higher than I-DOD. Or if battery discharged to below I-DOD, than battery will only discharge
again when SOC charged to 20%+ (I-DOD)/ 2 and SOC>105%-DOD (if need battery discharge immediately,
battery should be restarted);
4. Check on App if ti is set as charge time, during charge time, battery will not discharge (battery will charge in
priority during coincident time of charge/ discharge).
Battery not charge when PV power higher than load power:
Solution:
1. Check if charge voltage on App (Set→Basic Setting) 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.
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.
Battery does not charge:
Solution:
1. Make sure BMS communication is OK on SolarGo (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.

Checking Before Starting EM Up
About Wi-Fi Configuration
Q: Why cannot see Solar-WiFi* signal on mobile devices
A: Normally Solar-WiFi* signal could be searched right after inverter powered up. But Solar-WiFi signal will
disappear when BT connected to internet. If need to change settings, can connect to the router to change. If
cannot see Wi-Fi signal even not connect to router, then please try to reload Wi-Fi (please refer to EM user
manual page 19).
About Battery Operation
Q: Why battery does not discharge when grid is not available, while it discharges normally when grid is
available?
A: On APP, Off-Grid output and Back-Up function should be turned on to make battery discharge under Off-Grid
mode.
Q: Why there is no output on Back-Up side?
A: For Back-Up supply, the “Back-Up Supply” on SolarGo App must be turned on. Under Off-Grid mode or grid
power is disconnected, “Off-Grid Output Switch” function must be turned on as well.
Note: As turn “Off-Grid Output Switch” on, don’t restart inverter or battery, otherwise the function will switch off
automatically.
Q: Why battery switch always trip when starts it up (Lithium battery)?
A: The switch of lithium battery normally trips for 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 other reasons please contact GoodWe for
details.
Q: Which battery should I use for EM?
A: For BT series inverter, it could connect lithium batteries which have compatibility with BT series inverter with
nominal voltage from 180V to 600V. Compatible lithium batteries can see on battery list in SolarGo APP.
About SolarGo Operation and Monitoring
Q: Why Cannot save settings on SolarGo 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.
2. Make sure EM Under waiting mode (on App) before you change any settings on SolarGo App disconnect
grid/load/battery, only leave PV connected and then restart EM till see work as “wait” on 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: 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 App, some columns show NA, like battery SOH, etc. why is that?
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.
About Smart Meter and Power Limit Function
Q: How to Act Output Power Limit function?
A: For EM 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: If out-put power limit set as 0W,then there might still have deviation max 100W exporting to grid.
Q: Why there is still power expoprting to grid after 1 set power limit as 0W?
A: Export limit could theoretically to minimum 0W, but there will have a deviation of around 50-100W for EM
system.
Q: What is the max current allowed going through CT on SmartMeter?
A: The max current for CT is 120A.
Other Questions
Q: Is there a quick way to make the system work?
A: The shortest way, please refer to BT QUICK INSTALLATION INSTRUCTIONS and SolarGo APP INSTRUCTION.
Q: What kind of load can I connect on Back-Up side?
A: Please refer to user manual on page 12.
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: Normally if any problem caused by disobeys the instructions on user manual, we can provide technical
support to help to solve the problem, but cannot guarantee a replacement or returns. So if there is any special
conditions when you cannot 100% follow the instructions, please contact GoodWe for suggestions.
