EcoFlow STREAM Microinverter

Understand the EcoFlow STREAM Plug & Play Solar System

This microinverter allows you to utilize solar panels to build an EcoFlow STREAM Plug & Play Solar System, which turns your home balcony into a compact self-sufficient power plant. The system comprises the following main components:

By setting up this system, the microinverter will optimize solar power to meet the energy needs of your home appliances. Any excess power will be fed back into the grid, helping to reduce your electricity bill.

Electrical codes may vary by region. Before setting up a balcony solar system, check your local regulations and consult a qualified electrician to ensure everything is done safely and in compliance with the applicable laws.

Install the Microinverter

The microinverter should be installed on a stable surface and positioned ideally for power cable routing and optimal Wi-Fi signal reception. EcoFlow offers two mounting options: wall mounting or attachment to a solar panel. Detailed installation instructions are included in the product packaging and can be found at EcoFlow Support.

Option 1: Wall Mounting

Option 2: Solar Panel Attachment

Connect the Microinverter

After securely mounting the microinverter, connect the necessary power cables (both AC and DC sides).

Application 1: Home Outlet Connection (For the European Region)

1. Connect solar panels to the PV terminals on the microinverter using specified EcoFlow PV cables.
2. Connect the microinverter to a standard home outlet using a specified EcoFlow AC cable.

Caution: Avoid touching a solar panel's positive (+) and negative (-) wires simultaneously.

Application 2: Home Branch Circuit Connection (For the United Kingdom Region)

1. Power off the circuit breaker to disconnect the grid power supply.
2. Connect solar panels to the PV terminals on the microinverter using specified EcoFlow PV cables.
3. Connect the microinverter to a branch circuit breaker using a specified EcoFlow AC cable. The PE and Neutral wires should be connected separately to the PE-bar and Neutral-bar, and the Live wire should be connected to the terminal on the breaker that leads to the load side.

Professional Installation Required: This installation must be performed by a qualified electrician.

Power Must Be Off: Before beginning installation, ensure the power is switched off at the installation site.

Solar Input Specifications:

• Per MPPT: Vmax ≤60V, Imax ≤16A.
• For a single input, the maximum is 430W. For dual inputs, the total solar input is subject to local regulations.
• The microinverter supports two PV inputs. You can configure solar panels to match the microinverter's input capacity. Furthermore, solar panels connected to the same PV input terminal must have the same electrical specifications.

Recommended Cable:

• For PV Connection: EcoFlow STREAM Solar Panel Extension Cable
• For AC Connection: EcoFlow STREAM BKW-AC Cable or EcoFlow STREAM BKW DIY Cable

Grounding Considerations

Proper grounding is essential for safe operation. EcoFlow offers an AC cable with an equipment grounding conductor/a grounding plug. If the cable has been plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances, the device will be properly grounded. However, if you encounter the following situations, consult a qualified electrician:

• You are unsure whether the product is properly grounded;
• You find that the plug provided with the product does not fit the outlet.

If the installation site does not meet grounding requirements or specific grounding standards mandated by local codes, ask a qualified electrician to use the grounding terminal on this product to establish proper grounding. A qualified electrician is always required to carry out grounding work.
