Safety Instructions
Installation
Usage
1. The module overcurrent protection rating applies to DC fuses.
2. Do not plug or unplug any system connectors while the circuit is under load.
3. Make sure the re resistance rating of the system is up to standard, comply with local electrical safety regulations,
and congure module accessories (such as fuses, circuit breakers, grounding connectors, etc.) as needed.
4. Please make sure that the installation area of the solar panel system is well ventilated and the connectors are
clean and dry.
5. All solar system connections must be sealed to prevent moisture.
6. When installing and using solar system, be sure to follow the safety regulations for all other modules in the sys-
tem, including connecting wires and cables, connectors, controllers, charging regulators, inverters, accumulators,
and other rechargeable batteries.
7. Do not apply any substance that may block light (such as paint, adhesive, etc.) on the light-receiving surface of
the solar panel.
8. Do not directly irradiate the surface of the module with articially amplied sunlight.
9. Do not put heavy objects on the solar panel during use, to avoid damage to the panel.
1. This solar system is to be installed by a qualied solar installation company.
2. Do not disassemble the module or nameplate by yourself, otherwise this may void the warranty.
3. Please make sure to use the installation components (including connectors, connecting cables, and brackets)
provided by us. Before installation, the solar panel should be completely covered with opaque material and the
positive and negative terminals disconnected to prevent power generation.
4. Please carefully check whether the solar panel has broken glass or a damaged back panel. If it does, please stop
installing or using it immediately.
5. When installing, do not wear any jewelry made of metal, and only use insulated tools approved for electrical in-
stallation.
6. When multiple solar panels are installed in series or parallel, the cross-sectional area of the cable and the capaci-
ty of the connector must be appropriate to the maximum short circuit current of the system.
7. Do not install modules near open ames or inammables and explosives. Do not install solar system in places
with water immersion, watering devices, or sprinklers.
8. Do not let children approach the installation site or touch any electrical modules.
9. Do not step on the solar panel or any parts.
10. Do not touch the solar panel (especially the back panel) with sharp tools.
11. You must comply with local and national regulations during roof and ground installations

Pre-installation Requirements
How to Connect Multiple Solar Panels
You can connect multiple solar panels in series or parallel, but the series connection method is recommended.
Please purchase the extension cable, parallel cable, and other accessories required for the connection by yourself. It
should also be noted that all connections in a solar panel system should be made using solar panels with the same
specications. Connection method:
1. Series Connection
2. Parallel Connection
Series connection can increase the voltage. When connecting in series, connect the positive pole of one module to
the negative pole of the second module.
Parallel connection can increase the current value. For parallel connection, please connect the positive and negative
cables of one module and the second module correspondingly.

How to Use Mounting Hole
When installing the bracket, be sure to use the mounting holes reserved for the solar panel. Do not modify the
module frame without permission, otherwise this may void the warranty. Specic location as shown below:
How to Choose the Installation Environment
Mounting hole
Number: 12; size: 14*9mm(0.55*0.35in)
In order to ensure the normal operation of the solar panel, please choose the suitable installation environment ac-
cording to the following table:
No. Environmental conditions Range
1 Recommended operating temperature -20 to 50°C (-4 to 122°F)
2 Operating temperature limits -40 to 85°C (-40 to 185°F)
3 Storage temperature -20 to 50°C (-4 to 122°F)
4 Temperature <85RH%
* The operating environment temperature refers to the monthly average maximum and minimum
temperature of the installation site.
If you plan to use the module in a place with high humidity (>85RH%), please consult the EcoFlow technical
support team for a suitable installation method rst.
Install the solar panel in an area that will not be shaded throughout the year. Even small amounts of shade should
be avoided (e.g. overhead lines, dirt, snow).
For more solar system installation guidelines, please refer to your local solar system installation guide or the solar
manufacturer's installation requirements.

Installation Steps
Precautions
The installation methods listed in this manual are for reference only. Please purchase the required installation kit
yourself. For specic installation steps, please refer to the manual of the corresponding kit.
The installation tilt angle of the solar panel should be kept above 10°, otherwise dust accumulation and damage to
the performance of the module is likely. If the tilt angle is too small, please increase the frequency of cleaning the
solar panel.
During solar system installation, it is recommended to install solar panel with similar appearance and color
together.
The gap between two adjacent solar panels should not be less than 20mm. The minimum distance between the
frame of a single solar panel and the installation plane should be 40mm.
The maximum design load of the solar panel, as well as excessive forces due to thermal expansion of the support
structure, must be considered during system design. The specic system installation design is the responsibility of
the installation company.
Tilt Mount Bracket Installation
The system can exibly regulate the elevation angle via adjusting the bracket to keep the solar panel at a vertical
angle to the sunlight. It can also be fixed on a flat level for a long time. It is recommended that you place the
modules horizontally during use to ensure the stability of the system.
Please use the tilt mount bracket kit for the installation. The kit includes the xing bracket, adjusting bracket, and
attached bolts. If needed, please visit EcoFlow's ocial sales channel for the relevant purchase information.

Bolt Installation
The solar panels in this system can be xed on the bracket with a bolt kit. It is recommended that you place the
module vertically when using the bolts to ensure the stability of the system.
Please use the bolt kit to x the solar panel on the bracket system. The applied torques are 16–20 N·m for M8 and
14–18 N·m for M6. You need to purchase the bolt kit yourself. Please select anti-corrosion stainless steel fas-
tening materials.
Support Bracket Installation
The solar panels in this system can be xed parallel to the installation surface using the support brackets. Each module
requires the installation of at least eight support brackets to ensure the stability of the system.
Please use the support bracket kit to connect the solar panel, and x the solar panel to the pre-installation surface
with the drill screws. If needed, please visit EcoFlow's official sales channel for the relevant purchase
information on the kit.
How to Install
Fix the support bracket and the solar panel. Use the mounting hole to x the solar panel
in the pre-installation position
