2 Safety and Warning
01 02
A GoodWe BP series hybrid converter can upgrade a generic single phase PV grid-tied inverter into an energy-storage system.
During daytime, PV panels generate electricity which can be firstly supplied to the local loads, then the excess energy will be used to
charge the batteries via the hybrid converter. During the night, the battery will discharge. The electricity will be provided to the local
loads with the hybrid converter and the PV grid-tied inverter. The hybrid system improves the self-consumption ratio greatly.
● Installation, maintenance and connection of hybrid converter must be performed by qualified personnel, in compliance with local
electrical standards, wiring rules and the requirements of local power authorities and/or companies
● To avoid electric shock, PV input, PV output, battery connection of the hybrid converter must be terminated at least 5 minutes
before performing any installation or maintenance.
● The temperature of some parts of the hybrid converter may exceed 60 during operation. To avoid being burnt, do not touch it
during operation. Let it cool before touching it.
● Keep children away from the hybrid converter.
● Static electricity may damage electronic components. Appropriate method must be adopted to prevent such damage to the
equipment; otherwise the hybrid converter may be damaged and the warranty annulled.
● When exposed to sunlight, the PV array generates dangerous high DC voltage. Please operate according to our instructions, or it
will result in danger to life.
● Ensure the output voltage of the proposed PV array is lower than the maximum rated input voltage of the hybrid converter;
otherwise the equipment may be damaged and the warranty annulled.
● Do not open the front cover of the hybrid converter without permission. Apart from performing work at the wiring terminal (as
instructed in this manual), touching or changing components without authorization may cause injury to people, damage to
equipment and annulment of the warranty.
● Completely isolate the equipment should :disconnect the PV input, output terminal, disconnect the battery terminal or breaker.
● Prohibit inserting or pulling the PV and battery terminals when the hybrid converter is working.
● PV modules should have an IEC61730 class A rating.
● If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be
impaired.
Caution!
Failure to observe a warning indicated in
this manual may result in injury.

5.1 PV INPUT and TO INVERTER Connection
● Before connecting to PV input, please install a separate DC breaker or switch between hybrid converter and PV panels.
● Make sure that PV Input and TO INVERTER are connected correctly, otherwise the system cannot work, or the hybrid
converter may even get damaged. Referred to Figure 5.1-1.
● Before connecting PV panels, make sure PV input breaker or switch is turned off.
● Before connecting the PV input and TO INVERTER, ensure the plug connectors have the correct polarity. Incorrect polarity could
permanently damage the hybrid converter and PV inverter.
● PV panels should not be connected to the grounding conductor.
● Check the short-circuit current of the PV panels. The total short-circuit current must not exceed the Hybrid converter’s maximum
PV current.
● The open circuit voltage of the PV panels cannot exceed the maximum input voltage of the Hybrid converter.
● Must use DC plugs in accessory bag.
Installation instructions of SUNCLIX please refer to Figure 5.1-3.

Note:
1.The two DC connectors in accessory box are only used for the production!
2.There are two connecting cables of inverter, one has two male terminals, the other one has two female terminals.
● Before connecting to battery, please install a separate DC breaker (63A or above) between hybrid converter and battery.
This will ensure the machine can be securely disconnected during maintenance.
● Reversed polarity will damage the Hybrid converter!
● Be aware of electric shock and chemical hazards!
● It is a normal phenomenon that electric arc occurs when connecting battery to the connecting the battery to the hybrid converter
without using a DC breaker.
● It's very important for system safety and efficient operation to use the appropriate cable for battery connection. To reduce risk of
injury, please use the proper recommended cable size. Refer to Figure 5.2-1.

Suggestion: if the battery is to be installed indoors, please refer to the battery manufacturer's user manual for details.
● Suggestion: Batteries must be installed with a certain distance from each other, for details please refer to the battery
manufacturer's user manual.
● As for the number of cells used, it will be decided by the customer's choice, the choice must comply with the requirement that the
voltage range is 40-60V.
Please follow the steps below to implement the battery connection:
(1) Check the nominal voltage of batteries. The nominal output voltage should meet GoodWe’s product specification.
(2) Disconnect DC breaker between the hybrid converter and the battery.
(3) Disconnect screw cap from insulator.
(4) Disconnect waterproof ring from insulator.
(5) Put the cable through the components in this order: screw cap, waterproof ring, insulator, battery cover and battery terminal.
Refer to Figure 5.2-2.
(6) Compress the terminal head using a professional tool and screw down the screw cap slightly. Refer to Figure 5.2-3, Figure 5.2-4.
(7) Put battery terminals into the corresponding holes (Red to the positive terminal; Black to the negative terminal) and fasten them
by screwdriver and spanner (recommended torsion:50~70Kg-f.cm), then fasten battery cover with the pan head screws supplied in
the accessory bag. Refer to Figure 5.2-5, Figure 5.2-6, Figure 5.2-7.
(8) Screw down screw cap again.
(9) An earth wire terminal is set on the right hand side of the Hybrid converter. It must be connected to the earth wire, the earth wire
size should be the same as the phase conductor. Refer to Figure 5.2-8.

5.4 Communication Connection
The EzMeter can detect the grid voltage, magnitude and direction of current to control the working condition of the hybrid converter
via RS-485 communication. The cable length should not exceed 100m.
For the connection method of EzMeter & CT, please refer to Figure 5.3-1.
Please follow steps below to implement the EzMeter & CT connection:
(1) Connect the CT to the main ‘L’ line as the Figure 5.3-1 shows, making sure that the CT direction is ‘K→L’;
(2) Connect the EzMeter to the random ‘L’ and ‘N’ line, as per figure 5.3-1. To power up the EzMeter and detect the grid voltage,
please make sure that ’1’ connects to ‘L’ and ‘4’ connects to ‘N’.

There are two ready-made cables connected to the unit’s RS485 port; one cable is 3m long which is marked ‘To EzConverter’ and
should be connected to EzConverter INVERTER port, the other cable is 10m long which is marked ‘To EzMeter’ and should be
connected to EzMeter’s ‘RS485’ port.
Note: If not using the EzConverter and the BP is installed outside, please take out the ④ ‘To EzConverter’ cable by removing the
RS485 cover, then put the RS485 cover back and install the waterproof terminal.

5.5 EzManage App Illustration
The BP Series hybrid converter can be controlled by an APP called EzManage.
Current working status of system, PV Panel parameters, battery parameters,
meter communication status and BMS communication status can all be checked
by EzManage. Working modes can also be set by EzManage.
For IOS Systems, please go to AppStore and search for "EzManage", then
download and install it.
For Android Systems, please go to Google Play and search for "EzManage", then
download and install it.
The App can also be installed by scanning the QR code on the back cover of this
manual.
When the BP Series hybrid converter is working, please use mobile devices to
select the SSID of the hybrid converter (Factory default is SolarWiFi, and initial
password is 12345678. For any questions, please refer to the Wi-Fi Connection
Guide). After accessing the hybrid converter's Wi-Fi network, you can open the
App and operate the hybrid converter.
