Do not damage, smear, or rip off any warning labels on the equipment.
Do not hit, pull, drag, squeeze, or step on the equipment, or throw it into the fire, as there is a risk of explosion.
After installing, please clean the remains of the installation, such as boxes, clipped cable ties, ripped insulation materials, etc.
Do not modify or repair the equipment, please contact our customer service or qualified personnel if necessary.
Use tools and equipment correctly to prevent personal injuries and product damage.
Understand the components and function of the grid-tied PV power system. Make sure that all electrical connections, and voltage and frequency at the connection point meet the local microinverter grid-tie requirements.
Make sure the screws are tightened to the specified torque during installation (M512: 30 Kgfcm; ST512: 45 Kgfcm; M620: 90 Kgfcm).
If you only connect solar panels and the battery with the microinverter without plugging into the AC outlet, the microinverter shall be grounded.
It is strongly recommended to install an overcurrent circuit breaker between the equipment and the grid.
The equipment may get more than 70 °C (158 °F) while in use. Do not touch its enclosure before it cools down. Also, always keep the equipment out of reach of children and pets.
The installation location should be convenient for you to pull out the connectors.
Before you pull out the AC (or battery) connector from the microinverter, disconnect the cable from the AC socket (or battery’s) end.
Make sure the portable power station is off during the whole connection process.
You can only connect solar panels to the PV port and only connect an EcoFlow portable power station to the battery port.

Environment requirements

Make sure the equipment is installed, operated, or stored in a well-ventilated place.
Do not install or operate the equipment near flammable, explosive, corrosive, caustic, or moist sources.

Assembly

Pre-assembly

NOTICE This user manual only provides the cable connection method and the mounting method for the microinverter.
For installing the solar panel, please refer to the instructions for the solar panel and its accessories.
If you wish to verify the solar system, complete the assembly on a sunny day.

Select a location for the PowerStream Microinverter

Make sure that the microinverter is within the Wi-Fi coverage.
Do not place or install the microinverter in an area where flammable or explosive materials are stored.
The IP rating of the microinverter is IP 67, hence, it can be installed. either indoors or outdoors. However, the EcoFlow portable power station is not waterproof. If your system includes a portable power station, keep both of them indoors.

Measure the distance

The lengths of cables vary in different countries or regions. Please refer to the actual products.
Except for the standard BKW-Solar cable and the BKW-AC cable, other cables need to be purchased from the official website.

Assembly procedure

Place the microinverter on the Ecoflow portable power station
- If you need to mount the microinverter, please refer to “Mounting the Microinverter”.
Connect with solar panels
- NOTICE A BKW-Solar cable includes two groups of MC4 connectors, which can connect with two groups of solar panels.
- After the solar panels capture solar radiation, they provide direct current to the microinverter. At this time, the LED indicator will light up white.
- If you connect several solar panels in series or parallel as a group, refer to “Connecting several solar panels in series or parallel”.
- If you connect the EcoFlow River-series portable power station to the DC port of the microinverter, it is recommended to connect solar panels to the power station, otherwise, the energy will not be stored.
- For the connection, refer to the user manual of the power station. Download user manuals here.
Connect with the EcoFlow portable power station
- There are three types of battery connection cables for different EcoFlow portable power stations, as shown in the figures below.
- NOTICE Make sure the portable power station is off during the whole connection process.
- If you use the EcoFlow BKW-RIVER cable for the EcoFlow River-series portable power station, the power station only discharges power but does not receive a charge.
Connect to the power grid
- NOTICE Please confirm that the AC socket is switched on, and the power grid is being powered.
Turn on the EcoFlow portable power station
- NOTICE If your PowerStream balcony solar system does not include a portable power station, skip this step.
- After completing the connection, the LED indicator will light up green when the solar panel captures solar radiation and the microinverter outputs AC.
- It is highly recommended to install the protective case on the top of the microinverter to protect you from high-temperature burns. The protective case is in the box.

Connecting several solar panels in series or in parallel

NOTICE If you connect several solar panels in series or parallel as a group, make sure that the maximum operating voltage (Vm) and maximum operating current (Im) of each group do not exceed the maximum input voltage (55V) and maximum output current (13A) of the microinverter PV input.
The maximum operating voltage (Vm) and maximum operating current (Im) of solar panels must be consistent respectively.

Solar panels in series

Solar panels in both series and parallel

Mounting the microinverter

If your balcony solar system does not include a power station, you can mount the microinverter.
DANGER Wear protective goggles or gloves when drilling holes.

Mount on the wall

Use the installation board to locate the hole and drill two holes about 41 mm deep in the wall.
- Then, insert M5*40 into the holes.
- Install M5*12 in the corresponding positions on the back of the microinverter.
Insert ST5.525 into M540 through holes in the board.

Mount on the bracket

Install M3*6 in the corresponding positions on the back of the microinverter.
Install two M6*20 in two holes of the installation board, and tighten the M6 nuts on them.
- CAUTION Please install vertically ≤ 15° for stability and safety.

Grounding considerations

There is an earth wire inside the supplied BKW-AC cable, so grounding can be done directly by using this BKW-AC cable.

If you need to add an additional grounding conductor:

Tools and components (not provided): an M4*6 screw, a grounding wire (cross- section ≥ 4 mm²) with a connection tool, safety gloves, and a driller.

Find the grounding terminal on the bottom of the microinverter.
Insert M4*6 into the grounding terminal through the connection tool of the grounding cable.

EcoFlow App

NOTICE The figures are for reference only, please refer to the actual app interface.
Control, monitor, and customize your EcoFLow PowerStream microinverter from afar with the EcoFlow app.

Setting the power supply mode

NOTICE This feature can be enabled when the portable power station is connected.
On the page of your PowerStream system, tap > “Power supply mode”. Then, select the mode you need.
Prioritize power supply: Select this option if you want to prioritize meeting the power consumption of electrical appliances. In this mode, when the power supply exceeds the demand for electrical appliances, the portable power station will be charged.
When the demand for electrical appliances is less than the power supply, the portable power station will discharge.
Prioritize power storage: Select this option if you want to prioritize charging the portable power station until it reaches its charging limit. In this mode, the portable power station will not discharge to the microinverter.

Setting the AC output power demand

On the page of your PowerStream system, tap > “AC output power demand”.
The AC output power demand = Power demand from other loads + Load power of smart plugs

Firmware update

On the page of your PowerStream system, tap > “Firmware” to check the firmware version of the microinverter and the smart plug to update the firmware.
To update the microinverter separately, you can also update the firmware on the “Setting” page of your microinverter.

Page of your microinverter

In the list of your devices, tap the microinverter to go to the page of your microinverter.

Unplug the Cables

DANGER Do not remove the connector with your hand only. Please use the cable puller supplied with the product to assist in pulling out the connector.
If you have installed the protective case, please remove the protective case from the microinverter before you pull out the connector.

Where is the cable puller?

How to use the cable puller?

CAUTION Before you remove the battery connection cable, turn off the power station.

Remove connectors in the following order:

NOTICE Before you pull out the AC (or battery) connector from the microinverter, disconnect the cable from the AC socket (or battery’s) end.
