WIRELESS CONNECTION

PV Master App is only useful if your smartphone is connected to the GoodWe hybrid inverter by Wi-Fi or the Blue tooth method.

2.1 CONNECTION BY Wi-Fi

• By Wi-Fi: support direct connection to inverter Wi-Fi signal (Solar-WiFi *****) or connect smart phone(s) and inverter(s) in the same intranet system.

2.2 CONNECTION BY BLUE TOOTH

• By Blue Tooth: please replace the Wi-Fi module with a blue tooth device in the components box and power the inverter up.
  Then search Blue Tooth device “SOL_ BLE****” on PV Master.

• “***” means the last 8 characters of the inverter serial No.
• Scroll down the page to refresh the device list.
• Click the device to do further commissioning.
• If cannot see the device by refresh, please reboot PV Master to check again.

SYSTEM COMMISSIONING

3.1 CONNECTION TO NETWORK
3.1.1 Wi-Fi Configuration
Connect inverter Wi-Fi to the local network for remote monitoring on the GoodWe platform – SEMS Portal.
Steps:
Connect Solar-Wi-Fi→Open App→Choose the inverter you want configure→Click Set→Basic
Setting→Choose Safety Country→Select operation mode→Select battery model→CT Test.

NOTE:

1. “Configuration Completed” doesn’t mean network connection (inverter—network—GoodWe server) successfully. It means only the configuration process is finished. Please follow the “Wi-Fi” led statues on the inverter to make sure Wi-Fi is connected successfully to the GoodWe server or not.
2. In step 4 “DHCP” function could be closed to set a fixed IP address accessible to the local network (if there is a firewall for the local network).

3.2 OPERATION COMMISSIONING
Operation commissioning is the key function of PV Master, which enables the energy storage system to work normally as expected.

NOTE
Basic Setting: must-be settings to ensure the system work normally for all installations like safety code, battery model, operation mode, etc.
Advanced Setting: especially expected functions, which are optional depending on individual requirements like export power limit, unbalanced output function, etc.

3.2.1 Basic Settings
Steps:
Connect Solar-Wi-Fi→Open App→Choose the inverter you want configure→Click Set→Basic Setting→Choose Safety Country→Select operation mode→Select battery model→CT Test.

→ Select Safety Code:
Please select the right safety code based on your installation area. If it is not on the list, then Please select the right safety code based on your installation area. If it is not on the list, then please find one in “Other”.

→ Select Safety Code:
Here are 4 commonly used operation modes, which have their own operation logic as below:
A. General Mode
General Mode is to maximize self-use of PV power and minimize importing power from the grid, and the default logic is as below:
a. PV power is used to supply loads in priority (both Back-Up loads and On- Grid loads), then charge the battery. And, if there has exceeded power, will export to the grid (Controllable).
• Back-Up loads and On-Grid loads are supplied together with the same priority.
b. (If load power is higher) the load will consume PV power in priority, and the battery does supplement, then, if still not enough, buy power from the utility.

PV Supply Priority:

Load Consumption Priority:

B. Back-Up Mode
Back-Up mode is to save power into the battery for emergency use during a grid outage. Under backup mode, the battery stays at charge status, if utility is available, to make sure the battery has enough power reserved. During grid outage, battery charge/discharge will follow default logic to supplement PV supply to loads or charge if PV power is higher than loads.

System Logic When Utility is Available:

System Logic During Utility Outage:

C. Off-Grid Mode
Off-grid mode means the system does not connect to the grid. There will not be any electrical connection between the solar storage system and the utility under this mode, because the inverter itself will cut off the connection to the utility no matter AC cable is wired or not.
D. Economical Mode
Economical mode is an option to self-define battery charge/discharge time and power.
There are 4 editable different repeating logic, for each, you can set different date(s) and charge/discharge logics.

Rated Power: means the max charge power (%Pn) from the grid or max discharge power from the battery.

NOTES:

• All charge or discharge settings only work when the utility is available. During a utility outage, the economical mode does not work and the whole system follows the default mode.
• If an overlap of charge & discharge time happened at the same date & time, then charge logic takes priority.
• If the same charge or discharge date & time is repeated in different options, then the priority drops from Group 1 to Group 4.

→ Select Battery:
With GoodWe energy storage inverters, all compatible batteries will be listed inside the APP and the relative parameters of battery charge/discharge had been preset inside individual battery selections.
Selecting the right battery (same as what you use) for your system is very important for:

• Make sure the battery and inverter work on the preset parameters so that battery can work at its best condition and contribution.
• Make sure BMS communication between the inverter and battery works normally (selecting the wrong battery will cause BMS communication failure).

PV Master will read inverter information and selectively shows the compatible battery list.

If have any confusion on battery selection, please contact GoodWe for consultancy first before selecting PV Master.

3.2.2 Battery Ready Commissioning (only for EHR)
For the EHR series, if the battery function needs to be activated to update the system to energy storage, an activation code should be purchased from GoodWe or a Smart Meter as well. The whole activation procedure goes as below:

→ Activation Locally on PV Master
Steps:
Connect Solar-Wi-Fi or Blue Tooth→Open App→Choose the inverter→Set→Advanced Setting→Battery Function Activation→Fill in Activation Code→Success Notice→Exit and go for Basic Setting.

NOTE: “Battery Function Activation” option shows up only if the PV master is connected locally with an EHR series inverter (EH series without battery function).

3.2.3 Export Power Limit
The function is to limit the max power exporting to the grid. Normally it is only used if there is requirement for an export power limit, where solar power will be limited after supplying loads and charging batteries.
This function keeps “OFF” as default, you will be able to set up the maximum power allowed to inject to the public grid as turn on this function and preset a power value allowed for exporting.
Steps:
Connect Solar-Wi-Fi or Blue Tooth→Open App→Choose the inverter→Set→Advanced Setting→ Turn on “Export Power Limit”→ Set the Power Limit Value→Success Notice→Exit.

1. Turn On “Export Power”.
2. Set the “Power Limit” value, which means the max power allows exporting to the public grid.

NOTE: Export Power Limit function is able to be realized only if GoodWe Smart Meter is correctly wired and functions well in the electrical system.

3.2.4 ET Paralleling Commissioning
Commissioning of ET paralleling system includes that on PV Master and ProMate programs, here we give details of PV Master commissioning only.
The whole system-building procedure is as below:

For setting the Communication address of ET on PV Master:
Steps:
Connect Solar-Wi-Fi or Blue Tooth→Open App→Choose the inverter→Set→Advanced Setting→Find and set “Communication Address”→ Set→ Repeat the steps on other ETs→Exit.

3.2.5 Back-Up Supply
Back-up supply means there is a power supply on the inverter back-up side whether there is a grid or not. If the grid fails, it also needs to turn on the “Off-Grid Output Switch” to have access to backup supply power.

NOTE: Off-Grid Output Switch will stay activated after the first time being turned ON unless the inverter is rebooted.

TROUBLESHOOTING ASSISTANCE

Another function of PV Master is that it integrates troubleshooting assistance information and functions like Q&A, CT test, Wi-Fi diagnosing, etc. to help users or installers to find out and fix the problems, as well as system, and diagnose information which is deeper information to GoodWe technical service engineers for further analysis.
4.1 ALARM
In Alarm, there will be the system fault and operation warning status list up, including both real-time and historical records. This is basic information to know if there is a fault happened in the system.
Steps:
Connect to Inverter →Open App→ Choose the inverter you want configure→Param→Alarm

4.2 DIAGNOSE
Diagnose information is only for the real-time status of the system. It gives detailed reasons why the system is working on a specific status.
So, to get the right to diagnose information, must make sure the App is communicating to the inverter successfully.
Steps:
Connect to Inverter →Open App→ Choose inverter for check →Set→Diagnose Message

4.3 WI-FI DIAGNOSE
Wi-Fi Diagnose helps to find out the problem in the Wi-Fi communication route. It diagnosis result will be the possible reason and troubleshooting suggestions.
Steps:
Connect to Solar-WiFi →Open App→ Set→Wi-Fi Diagnose→Start Diagnosis

NOTE: Wi-Fi Diagnose is only available if PV Master is connecting to inverter Solar-WiFi signal directly.
4.4 RESET OVERLOAD HISTORY
This function is used to clean up backup overload to reset the waiting time for backup self-checking, as the waiting time will increase triply every time if the overload condition continues:
Steps:
Connect to Inverter→Open App→ Set→Advanced Setting→Reset Overload History

NOTE: Length of time A is different depending on the requirement of different safety codes.
4.5 METER DETECTION
Meter Detection is used to auto-check if Smart Meter and CT are connected in the right way or not in the GoodWe energy storage system.
Steps:
Connect to Solar-WiFi →Open App→ Set→Meter Test→ Turn On “Test”→Test Result.

NOTE:
→There is another port for Meter Test, the last step of Basic Setting.
→Meter Test functions only if the battery if connected and BMS communication is all right.

4.6 Q &A INSTRUCTION
In PV Master, we have prepared a Q&A part for users and installers to look for a solution for some commonly happening problems and confusion.
Steps:
Connect to Inverter→Open App→ Set→Q&A→Choose Inverter Model→Q&A List
NOTE: Part of the Q&A information here is based on the experience of GoodWe technical engineers. And it is not13 / 16 updated frequently, so if there is any confusion on the Q&A list, or have a conflict against your knowledge, please confirm with GoodWe technical support first.

LOCAL MONITORING

5.1 OVERVIEW INFORMATION
Overview information tells the basic system operation status and general operation data and settings. Data refresh frequency is 3 seconds.

5.2 SYSTEM PARAMETERS
System parameters are very important for GoodWe technicians if you need to turn to GoodWe service engineers for help.
Steps:
Connect to Inverter→Open App→ Param.
NOTE: With lithium battery, all battery data is transferred directly from battery BMS system, and honestly refl ected on APP without any calculation or processing.

OTHER FUNCTIONS

6.1 UNBALANCE OUTPUT FUNCTION
The unbalanced output function is only for three-phase energy storage inverters. At default, this function is OFF and can switch on depending on the requirement.
Steps:
Connect to Inverter→Open App→Set→Advanced Setting→Turn On Grid-Connected Side Unbalance Output→Exit.

NOTE:
→Unbalance output works only if the 3-phase smart meter is connected and communicates with the inverter well.
→This function is only for inverter on-grid side output, for the backup side of the inverter, the unbalanced output is a default preset logic.

6.2 GRID QUALITY DETECTION AND LOW SENSITIVITY
Grid Quality Detection:
Allow the system to switch to off-grid operation mode if grid quality is not good (voltage not stable, the electric wave is bad, etc.) If turn this function OFF, then the system turns to off-grid mode only if the grid shutdown or the grid voltage goes out of the requirement range of the chosen safety country.
Low sensitivity:
Obtund the sensitivity of grid quality detection if the system turns to off- grid mode so frequently because of grid quality issues etc. This function is editable only if “Grid Quality Detection” is turned ON.
