• Use the DC plugs in the accessory box.

Note: There will be MC4 or Amphenol plugs in accessory box, the detailed connection as below:

Prepare PV cables and DC plugs

Prepare PV cables and DC connectors

Ground cable shall be connected to ground plate on grid side

Carry the inverter by holding the heating sink on two sides and Place the inverter on the mounting bracket.

Note: Make sure the heat sink on inverter is right joint with mounting bracket.

A lock could be used for anti-theft if it is necessary for individual requirement.

Note：

• Please use DC plugs and connectors in GoodWe accessory box

• PV cable should be standard, 2.5-4mm cable

Screw the cap on and plug onto inverter side

The polarity of PV strings or on the inverter cannot be connected by reversely, otherwise inverter could be damaged.

Note：

• PV cable must be tightly crimped into the connectors

• For Amphenol connector, the limit buckle cannot be pressed

Note：

• There will be a click sound if connectors are inset correctly into DC plugs

• BATTERY PROTECTION DESCRIPTION

Battery will act a protective charge/discharge current limitation under any condition as below:

• Battery SOC is lower than I-DOD

• Battery voltage lower than discharge voltage

• Battery over temperature protection

• Battery communication abnormal for lithium battery

• BMS limitation for lithium battery

When charge/discharge current limitation protection happens:

• Please be careful against any electric shock or chemicall hazard.

• Make sure there is an external DC break (≥63A) connected for battery without attached DC break.

Battery wiring connection process is as below:

Make sure battery switch is oﬀ and battery nominal voltage meet EM speciﬁcation before connecting battery to inverter make sure inverter is totally isolated from PV and AC power.

[4]

Prepare battery cables and accessories and put battery power cable through battery cover

Note：

• Please use accessories from GoodWe box

• Battery power cable should be 20~25mm

Use special tool to crimp

Make battery terminals

• Strip cable coat, revealing 10mm length of metal core

• Use special crimper to compress battery terminal tightly

• Under on-grid mode, battery charge/discharge operation could be abnormal

• Under oﬀ-grid mode, Back-Up supply will shut down

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.

2.4.3 ON-GRID & BACK-UP CONNECTION

1. Use a separate AC break for individual inverter

2. On AC side, the individual break should be connected before loads (between inverter and loads)

Connect battery terminals onto inverter

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.

Connect the assambled AC terminals onto inverter.

Note：Make sure it is connected to ‘Back-Up’side (other side connected to public grid).

Declartion For Back-Up Loads

GoodWe EM inverter is able to supply a continuous 2300VA output or max 3500VA in less than 10 seconds on Back-Up side to support Back-Up loads. And the inverter has self-protection derating at high ambient temperature.

• Accepted Back-Up loads: Television, computer, fridge, Fan, Illumination Lamps, Microwave Oven, Electrical Rice Cooker and router etc.

• Unacceptable Back-Up loads: Air Conditioner, Water Pump, Heaters, Washing Machine, Electromagnetic Oven, Compression Engine, Hair drier and Dust Cleaner etc. and other loads with high inrush current at start-up.

Problems during operation

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).

Checking as Start EM Up and Turn On AC Power

SmartMeter Communication: Turn oﬀ PV and battery, turn on Loads, check if R-P led is solid or not (4.2-5). If “R-P” is not solid, means CT connected by reversed or on a wrong phase, please check:

1.if connection between SmartMeter and CT (port 1 and 4 on SmartMeter) is OK

2.Make sure CT connected between house loads and grid, follow the House→Grid direction on CT(4.2-5).

3. Make sure CT is connected on the same phase with the power cable of SmartMeter.

Battery Settings, BMS Communication and Safety Country: After connecting Solar-WiFi* (* means the

last 8 characters of the inverter serial No.), check on SolarGo App Param to make sure battery type is right what you have installed, and Safety Country is right. If not right, please set it right in “Set”

NOTE:

1.For lead-acid battery: All the settings should comply with the parameter of the battery, and please contact GoodWe for advices

2.For lithium batteries, BMS status is “Communication OK”

If APP BMS Status on APP says “NG” or “NA”, please check if battery wiring and settings are all right following battery connection SOP in EM QUICK INSTALLATION INSTRUCTIONS

3. Make sure CT is connected on the same phase with the power cable of SmartMeter.

4.2-5

4.2-6

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

Questions & Answers (Q & A)

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).

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 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.

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.
