Product Introduction:
 
SL03 series controllers are kinds of intelligent multi-functional solar charge and discharge controller. This series adopts the
new 32bit microprocessor to collect and compute various parameters, which is much more accurate and speedy than the former
8bit microprocessor. The customized LCD with wide temperature range is with vivid operation interface; the latest proprietary
technology solves the problem of voltage display of solar panel. Nearly all parameters can be shown and set up flexibly. All of
the multi-meter and other voltage and current instruments can be replaced by this controller, which can satisfy your various
demands.
 Product Features:
 
●Newly Upgraded: Data collection by 32bit microprocessor with 4096 resolution ratio is much more accurate than the
former 8bit microprocessor with 1024 resolution ratio.
●Newly Upgraded: The voltage of solar panel can be shown and checked.
●Newly Upgraded: The results and states of each monitoring parameters can be automatically showed by turns
(automatic-scanning).
●Newly Upgraded: Light-operated sensitivity is set flexibility which can recognize day and night reliably according to the
voltage of solar panel.
●Newly Upgraded: Floating charge voltage can also be set, which can be especially applied to charge and discharge at the
same time, controlling the voltage of battery flexibly
●Newly Upgraded: The protected USB5V voltage-stabilized source output, for other 5V load like mobile phone charging
that compatible USB. The energy consumption will automatically reduce when non-loaded, we don’t need to control it by hand
switch, realizing the plug and play.
●Newly Upgraded: The charge-discharge parameters of wide range can be adjusted flexibly, which is suitable for various
kinds of battery, such as lithium battery. The old and new battery can all be applied to.
●Newly Upgraded: Automatic temperature compensation and adjustable compensating parameter, for example, the lithium
battery can choose the closing temperature compensation.
●Newly Upgraded: Flame-retardant plastic shell
●Newly Upgraded: LCD display screen with wide temperature range is with visual graphic symbol display.
●compact keys operation
●automatic identification of system voltage classes
●intelligent PWM charge mode
●Configurable load operating mode
●accumulative function of charge-discharge AH
●telecommunication monitoring function
(The function needs to WINCONG order)
●back discharge protection of battery
●low-voltage protection of battery
●transposition protection of battery
●overload and short-circuit protection
Installation Instructions:
 
1. Preparing the related instruments and cables. We advise you choosing the right cable according that the ampere density﹤
4A/mm2, which can diminish line drop. Checking whether the installation site conforms to related safety requirement.
Please avoid installing and using the controller in moist, dusty and environment with flammable, combustible and corrosive
gas.
2. Set the controller in vertical plane and the pitch of open holes can see the form parameter for detail. In order to ensure the
well thermal condition of the controller, please reserve 10cm above and under the controller. The controller will dissipate
heat when operating. Without enough ventilate (such as setting in the control cabinet), the controller will restrain the past
current to avoid overheating. We suggest you to install cooling fan according to the scene condition.
3. As shown in installation connection diagram, the battery, solar panel, load and controller should be connected by turns.
Please connect the battery first, and then the solar panel or load. The notice the consistency of positive (+) and negative (-)
with the controller. The virtual voltage of the battery this controller supported should be higher than 8V. (48**A>26V)
4. The temperature sensor of the controller for environment temperature detecting is integrated at the top left of the controller
panel, thus users don’t need externally connect the temperature sensor. The controller and battery should be set in the same
environment with close temperature so that the controller can conduct temperature compensation.
5. If you order the remote monitoring function, please insert one end of the attached communication cable into the USB port of
the bottom right of the controller and connect the other end to the monitoring display or computer. The USB port of the
non-customized convention product is without the telecommunication function, only output5V/1A for other 5V load like
mobile phone charging that compatible USB.
Notice: The controller should be installed in a upright and suspended way, the traces of photovoltaic panels and load
lights should go as "U" arc-shaped under the controller and be fixed well to avoid the rain directly flowing
into the controller along with the electric wire, All terminals and tighten the screws to avoid poor contact.
Warning: Controller may be burned away when several installation errors happen at the same time. Notice that other
power cannot be used to replace the solar panel to connect the system for testing, otherwise it may burn the
controller. Although this equipment has a multiple protective measures, this is not a panacea. And the proper
use of controller is much important even than the users to do the best protective measures.
