How It Works
Place your solar panel in an area where you can get the most
possible sunlight and adjust the angle to the sun.

Build a connection between the solar panel and your solar
generators.

All solar panels must be exposed to direct sunlight, and avoid any
possible shelter like buildings and trees.
Solar panels angled at 30-60 degrees from a flat surface will harvest
the solar energy that is most possible.
If your panels must adhere to other surfaces, you need to avoid the
damp or irregular surfaces as they might bring a bit of distortion after
a long time of sunlight exposure. (we can rescue it after a second
long time exposure.)
Please choose the sunny hours in the day (9: 00 am to 5:00 pm) and
panels operate at peak efficiency when the sun is most direct-typi-
cally around mid-day (12:00 am-1:00 pm)

Solar panels generate electricity when panels meet sunlight, so
please protect them with a cloth before you plug in a device.
Plugin the cable to the input of your device first, then the other end
of the cable goes towards the output of the solar panel.
Remove the cloth and you will find a charging sign on your laptop, if
not, please build the connection again or replace another charging
cable.
If there shows up a charging sign, you can settle your device to a
cool place for better heat dissipation and turn off your device to save
the loss of energy during its running hours, especially for laptops.

How to chain multiple solar panels together

It is also designed for charging 12V/24V Lead-Acid batteries, including
lithium and other equipment, please do pair the charging with a solar
regulator to protect the battery system from overcharging.

You can add more panels together with MC4 Y branch parallel
adapter cable to get a different output: Voltages are additive when
Panels are connected directly in series, and the currents are additive
when panels are connected directly in parallel.
Only panels with similar electrical output should be connected in the
same string to avoid mismatch effects.
How to build the series connection Every panel is equipped with One
stranded, PV-rated, output MC4 cable. The Positive connector is a
male connector and the negative connector is a female connector,
these wires by themselves are rated for] series connections.
When two solar panels are used together in series, insert the MC4
male connector of the first solar panel into the MC4 female
connector of the second one, and a 350W solar panel is obtained to
charge your power station.

MC4 Connectors
Keep connectors dry and clean, and ensure that connector caps are
hand tight before connecting the panel.
Do not attempt making an electrical connection with wet, soiled,
or other faulty connectors.
To better preserve its service life, please avoid sunlight exposure
and water immersion of the connectors, and avoid connectors
resting on the ground or roof surface.
Faulty connections will result in electrical shock. Please check all
electrical connections at least once every 6 months. Make sure that
all locking connectors are fully fastened and locked.

Maintenance
This solar panel is mainly for emergency charging purposes, we do
not suggest a long time of outdoor exposure as it may shorten the
lifespan of this product.
Not bendable, please handle the solar panel with care, and avoid
hitting it with sharp objects or knocking heavily on it.
It is normal that solar panels got hot during working hours and
please store them in the box after they cool down.
Dirt and dust can accumulate on the surface over time, this can
cause a general decrease in power output, we recommend periodic
cleaning for panels with a mild, non-abrasive cleaning agent.
Use and storage temperature conditions should be at -20°C---60°C;

Warm Tips
Please do not try to modify the PCB circuit inside the back junction
box unless you are a professional technician, or we are not
responsible for such a result.
The solar panel charger is built with an anti-flow resistant preventer
inside, it will not occur the backflow phenomenon.
Installing a solar PV system may require specialized skills and
knowledge. Otherwise, it is suggested to have it designed or
inquired with a qualified installer.
