Information

Solar panel is a mobile power source for various types of small devices or
powerbanks. It is perfect for charging car batteries 12V, or powering
mobile devices such as phones, laptops, tablets. The panel can be used
on camping, boats. In the set with additional external battery or powerbank
will provide power to the previously mentioned devices and emergency
situations..

Specific safety and health regulations



The controller automatically recognizes and adapts to 12V/24V.

Make sure that the battery to be charged has sufficient voltage, this
information is important for the voltage controller to recognize the
type of battery before the first installation



The voltage controller is dedicated for lithium batteries and all types

of lead acid (OPEN, AGM, GEL) batteries



The voltage controller is dedicated for all types of lead acid batteries

(OPEN, AGM, GEL). It is suitable for lithium-ion (tri-component
lithium batteries), as well as for lithium-polymer (lithium-iron-
phosphate) batteries.



The voltage regulator is dedicated to the solar panel only. Never

connect other power sources to this regulator



The controller heats up during operation. Make sure that the

controller is installed on a flat, well-ventilated surface

Product features voltage controller



Built-in controller, allows you to adjust parameters



Fully 3-stage PWM charge management



Built-in short circuit protection, wrong polarity protection, overload

protection



Dual MOSFET reverse current protection



The controller has a function to support both lithium type battery and

lead acid battery (in the battery type interface, hold down the switch
setting button for 3 seconds) by default the lithium battery is set.

How to connect the scratches E



Connect the battery to the controller, paying attention to the polarity

of the wires



Connect the solar panel to the controller, paying attention to the

polarity of the wires



Connect the additional receiver to the controller, paying attention to

the polarity of the wires

The reverse order applies when uninstalling devices
CAUTION! Incorrect uninstallation order may damage the driver!

NOTICE!

When charging the device, pay attention to its batteries. The charging
process itself causes significant heating of the battery. In addition,
exposure of the charged device to sunlight, accumulates the effect of
temperature increase. When the temperature limit is exceeded,
spontaneous combustion or even explosion may occur. When charging,
use caution and do not leave devices unattended.

Preparing the solar panel for operation



Lay out the solar panel



To make the best use of the incident sunlight, position the panels

with the absorbing surface at a 90º angle to the sun's rays.



Panel positioning should be controlled and adjusted to get the best

performance.



Panel angle settings will vary depending on the time of year. The

angle will be flatter at midday in summer, while others will be more
vertical on a winter morning.
