Solar Charge Controller 6830-122-C10/15/20
2013-06-25 2 Version 6
2 General Information
2.1 Product Overview
Thank you for selecting U-Tron LS series solar light controller that adopts
the most advanced digital technique and operates fully automatically. The
Pulse Width Modulation (PWM) battery charging can greatly increase the
lifetime of battery. It has various unique functions and quite easy to use, such
as:
•
12/24V automatic recognition
•
High efficient Series PWM charging, increase the battery lifetime and
improve the solar system performance.
•
Use MOSFET as electronic switch, without any mechanical switch
•
Widely used, automatically recognize day/night.
•
Digital LED menu, only one key solve all setting simply
•
Intelligent timer function with 1-15 hours option
•
Unique dual timer function, enhance the flexibility of street light system.
•
Gel, Sealed and Flooded battery type option.
•
Adopt temperature compensation, correct the charging and discharging
parameters automatically and improve the battery lifetime.
•
Electronic protection: Overheating, over charging, over discharging,
overload,
and short circuit.
•
Reverse protection: any combination of solar module and battery.
The controller is for off-grid solar system, especially in solar light system,
and protects the battery from being over charged by the solar module and
over discharged by the loads. The charging process has been optimized for
long battery life and improved system performance. The comprehensive
self-diagnostics and electronic protection functions can prevent damage from
installation mistakes or system faults.
Though the controller is easy to operate and use, please take your time to
read this manual and become familiar with it. This will help you make full
use of all the functions and improve your solar PV system.

3 Installation Instructions
3.1 General Installation Notes
•
Read through the entire installation section first before beginning installation.
•
Be very careful when working with batteries. Wear eye protection. Have
fresh water available to wash and clean any contact with battery acid.
•
Uses insulated tools and avoid placing metal objects near the batteries.
•
Explosive battery gasses may be present during charging. Be certain there
is sufficient ventilation to release the gasses.
•
Avoid direct sunlight and do not install in locations where water can enter
the controller.
•
Loose power connections and/or corroded wires may result in resistive
connections that melt wire insulation, burn surrounding materials, or even
cause fire. Ensure tight connections and use cable clamps to secure cables
and prevent them from swaying in mobile applications.
•
Use with Gel, Sealed or Flooded batteries only.
•
Battery connection may be wired to one battery or a bank of batteries. The
following instructions refer to a singular battery, but it is implied that the
battery connection can be made to either one battery or a group of
batteries in a battery bank.
•
Select the system cables according to 3A/mm

3.2 Mounting
NOTE: When mounting the controller, ensure free air
through the controller heat sink fins. There should be at
least 6 inches (150 mm) of clearance above and below the
controller to allow for cooling. If mounted in an
enclosure, ventilation is highly recommended.
WARNING: Risk of explosion! Never install the
controller in a sealed enclose with flooded batteries! Do
not install in a confined area where battery gassed can
accumulate.
Step 1: Choose Mounting Location
Locate the controller on a vertical surface protected from direct sun, high
temperature, and water. And make sure good ventilation.
Step 2: Check for clearance
Place the controller in the location where it will be mounted. Verify that
there is sufficient room to run wires and that there is sufficient room above
and below the controller for air flow.
