Warning
Please use insulated tools to reduce the risk of electric shock.
Please adopt appropriate protective measures (non-slip gloves, work clothes, etc.) to avoid
direct contact with 30V DC or higher, and avoid direct contact with sharp edges during
installation. Please do not wear metal ornaments during installation to avoid poking through
the Galaxy* lightweight products and causing electric shock hazards.
DO NOT install the product in rainy weather or strong wind.
DO NOT allow children or unauthorized personnel to approach the installation area or the

storage area of Galaxy* Lightweight products.
During installation or wiring of Galaxy* Lightweight products, if the circuit breaker and
overcurrent protection circuit breaker cannot be turned on or the inverter cannot be turned
off, then use an opaque material to cover the array Galaxy* Lightweight products to stop the
power output.
Do not use or install Galaxy* Lightweight products that have been damaged.
If the surface material is damaged or worn, direct contact with the surface of Galaxy*
lightweight products may result in electric shock.
Do not attempt to repair any part of the Galaxy* Lightweight product.
The lid of the junction box should be kept closed at all times.
Do not disassemble, modify, or move any part of the Galaxy* Lightweight product.
Do not artificially concentrate light on Galaxy* lightweight products.
It is important to note that only one piece of product can be moved in a single operation
when installing the Galaxy* products.
Installers are advised to consider additional hazards and local regulations relevant to the use
of a hot air weld gun including but not limited to welding at height, power cord management,
burns risks, restraint system management in the presence of a heat source, and consideration
for fumes and vapors, specifically:
Always lie the tool on a non-flammable surface & keep the hot air stream well away from
combustible materials, including combustible materials hidden behind ceilings, walls,
cavities or floors.
Do not point the hot air stream at the same spot for extended periods. Incorrect use can
cause fire.
Do not touch the element housing or nozzle with any part of the body during use as they
get very hot and there is a danger of serious injury by burning.
When working with plastics, varnish or similar materials vapors/gases/smoke develop
which can be harmful.

Do not breathe in vapors/gasses/smoke as they can be highly toxic.
Always provide good ventilation of the working area with an extraction system and/or
wear a respirator.
Keep the hot air welding unit dry. Do not use in the rain or in damp conditions. Always store the hot air
welding unit in a dry place.
Be careful
Before installing Galaxy* Lightweight products, the relevant authorities should be contacted
to obtain information about the installation site, construction permits or impact on roof
warranty, and the requirements for installation and inspection should be observed.
Check the applicable building codes to ensure that the building and its structure (roof,
exterior façade, load bearing, etc.) in which Galaxy* lightweight products are to be installed
have adequate load-bearing capacity.
Ensure that Galaxy* Lightweight products are installed on a fireproof roof, when installing
Galaxy* Lightweight products.
Galaxy* Lightweight products are compliant with Safety Class II. These Galaxy* Lightweight
products can be used in systems where the public is likely to be exposed to voltages greater
than 50V or power greater than 240W.
The installation surface should be flat and free of pits or bumps.
Galaxy* lightweight products must not be installed near flames or combustible objects.
Galaxy* lightweight products must not be immersed in water (pure or salt water), installed in
environments that are permanently wet (pure or salt water) (e.g. fountains, waves, etc.) or in
locations where water is likely to accumulate (e.g. potholes, drainage inlets, etc.).
There is a risk of corrosion if Galaxy* lightweight products are placed in salt spray (i.e., marine
environments) or environments containing sulfur (i.e., sulfur-containing sources, volcanoes,
etc.).
Ensure that Galaxy* Lightweight products meet the overall technical requirements of the
GOODWE(GUANGDE)POWER SUPPLY TECHNOLOGY CO., LTD.

system.
Ensure that other system components do not cause damaging mechanical or electrical
performance effects on Galaxy* Lightweight products.
It is allowed to connect Galaxy* Lightweight products in series to increase the voltage or in
parallel to increase the current. When connected in series, the positive terminal of the Galaxy*
Lightweight product is connected to the next negative terminal. When connected in parallel,
the positive terminal of the Galaxy* Light product is connected to the positive terminal of the
next Galaxy* Light product.
To avoid (or minimize) the mismatch effect of the array, it is recommended to connect Galaxy*
Lightweight products with similar electrical properties on the same string.
To reduce the risk of indirect lightning strikes, the system should be designed to avoid the
creation of loops.
Galaxy* lightweight products should be securely fastened so that they can withstand all
possible loads, including wind and snow loads.
Secondary handling should be avoided as much as possible during the installation of Galaxy*
lightweight products.
Please ensure that the installation location of Galaxy* Lightweight products is free from
shading all year round, as shadows can cause a decrease in the power generation of Galaxy*
Lightweight products. Hot spots and long-term heat generation from diodes caused by
frequent shading of Galaxy* Lightweight products can affect the service life of Galaxy*
Lightweight products.
5、Installation work of Galaxy** lightweight products
5.1 Unpacking and stacking (storage and unpacking)
To ensure the safety of Galaxy* Lightweight products during transportation, it is better to
open the packaging box of Galaxy* Lightweight product after reaching the installation site.
Check whether the box is damaged before unpacking.
It is advised that unpackers wear non-slip gloves in advance.
GOODWE(GUANGDE)POWER SUPPLY TECHNOLOGY CO., LTD.
Page 7
Galaxy* lightweight products should be stored in a dry and ventilated environment.

scratches can directly affect the safety of Galaxy* Lightweight products.
DO NOT place Galaxy* lightweight products in an environment that is not reliably supported
or not fixed.
Changing the wiring of the bypass diode is prohibited.
All electrical connectors need to be kept clean and dry.
Galaxy* lightweight products are not allowed to be stacked flat and the quantity should not
exceed 3 pieces. The junction box shall not be in direct contact with the front side.
5.2 checking
Please check whether the surface of Galaxy* Lightweight products is damaged, if there is
damage or wear on the surface of the products, please do not use the product.
Please check whether the junction box, connectors and cables are damaged , please do not
use the product if there is damage.
Do NOT apply adhesives, paint, label or any other product on the surface of Galaxy*
Lightweight products.
5.3 Roof Substrate requirements
The base layer application scenario includes pitched metal roof and flat roof. and TPO rolls
need to be laid on the base layer.
The roof substrate needs to be covered with TPO material.

5.4 Chalk line Positioning
Measure the roof and determine the position of Galaxy* lightweight products according to
the design drawings.
5.5 Carrying
To avoid damaging the cells, two people are required to lift the four corners of the Galaxy*
Lightweight product (avoiding touching the position of the cells) at the same time when
carrying it.
The downward bending distance of Galaxy* lightweight products should not exceed 300mm.
Please carefully position Galaxy into predestined location.
Galaxy* lightweight products should be carried upright as much as possible when handled
manually. Do NOT twist the product during transportation.
Care is required during the handling of Galaxy* lightweight products to avoid them bumping
into the ground or other sharp, hard objects.
5.6 Installation
