EXPLANATION

HYBIRD LED INDICATORS

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.

Battery negative(BAT-) on inveter side is not grounded as default design.

Connecting BAT- to EARTH are strictly forbidden.

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 s Off-Grid System Connection

Diagram in 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’.

Declaration For Back-Up Function

GoodWe BT series bi-directional inverters are able to supply over load output power at its' back-up. For details please refer to the technical parameters of GoodWe BT series inverter(4.3 se) And the inverter has self-protection derating at high ambient temperature. The below statement lays out GoodWe general policies governing the energy storage inverters of the series ES, EM, SBP, ET, EH,BH and BT.

1. 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.

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 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.

Accepted loads as below:

• Inductive Load: 1.5P non-frequency conversion air-conditioner can be connect to back-up side. Two

or more non-frequency conversion air-conditioner connect to back-up side may cause UPS mode unstable.

• Capacitive Load: Total power <= 0.6 x nominal power of model. (Any load with high inrush current

at start-up is not accepted.)

• For complicated application, please contact GoodWe's after service.

Note:

For a convenient maintenance, Please installed a

“4Pole3Throw”on Back-Up and On-Grid side. Then it

1. Load is supplied from Back-Up side.

2. Load is isolated.

3. Load is supplied from grid side.

is adjustable to support load by Back-Up or by grid or

just leave it there. (Figure 2.4.2-7)

Figure 2.4.2-7

Declaration For Back-Up Overload Protection

Inverer will restart itself as overload protection happens. The preparation time for restarting will be longer and longer (max one hour) if overload protection repeats. Take following steps to restart inverter immediately.

• Decrease Back-up load power within max limitation

• On PV Master → Adcanced Setting → Click “Reset Back-Up Overload History”.

2.4.3 SMART METER & CT CONNECTION

Make sure AC cable is totally isolated from AC power before connecting Smart Meter &

[6]

C T.

The Smart Meter with CT in GoodWe product box is compulsory for BT system installation, used to detect grid voltage and current direction and magnitude, further to instruct the operation condition of BT inverter via RS485 communication.

Note

1. The Smart Meter with CT is well configured, please do not change any setting on Smart Meter.

2. One Smart Meter can only be used for one BT inverter.

3. Three CTs must be used for one Smart Meter, and must be connected on the same phase with Smart Meter power cable.

POWER ENERGY COM

Note:

For compatible lithium batteries, BMS status is "communication OK" after selecting the right battery company.

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 BT user manual page 17).

Q: Why cannot connect Solar-WiFi* signal on my phone?

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.

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 PV Master 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: On Portal, why battery SOC has a sudden jump up to 95%?

A: This normally happens on when BMS communication fail on lithium. If battery enter float charge,

SOC will be reset to 95% compulsively.

Page 14

Q: Why battery cannot be fully charged to 100%?

A: Battery will stop charge when battery voltage reaches charge voltage set on PV Master APP.

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 BT?

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 PV Master APP .

About PV Master Operation and Monitoring

Q: Can I use other brand Meter to take over Smart Meter in BT system or change some settings

on Smart Meter?

A: No, because the communication protocol is inset between inverter and Smart Meter, other brand

Meter cannot communicate. Also any manual setting change could cause Meter communication failure.

Q: What is the max current allowed going 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: The shortest way, please refer to BT QUICK INSTALLATION INSTRUCTIONS and PV MASTER

APP INSTRUCTION.

Q: What kind of load can I connect on Back-Up side?

A: Please refer to user manual on page 12.

Q: Why Cannot save settings on PV Master 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 restart inverter 10mins later after you do some settings because inverter will save settings every 10 mins under normal mode. We recommend you change setting parameters when inverter under waiting mode.

Q: On the App, why the data on the homepage and Param page is different, like charge/dis-

charge, 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 communica-

tion 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 BT 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: 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.

Q: Why there is still power exporting to grid after I set power limit as 0W?

A: Export limit could theoretically to minimum 0W, but there will have a deviation of around 50-100W

for BT system.
