Solar Controller
C2430 / C2460 / C4860 USER MANUAL
Thank you for purchasing our solar controller ,please read these instructions before use.
1. Safety
Full consideration to the safety of persons and property has been given when designing the products. However the incorrect connection may cause the system breakdown
or even safety accident. For your safety and benefits, the following rules must be complied during the operation.
n Installation of this product shall be carried out by professional staffs.
n Prevent any liquid spattered on the controller. Do not clean the controller with wet cloth.
n Keep children and incapable persons away from the controller.
n Keep the controller away from electrical heater, heating machine and other high temperature electrical appliances; avoid the controller from direct sunlight.
n Please check the rated voltage of solar panel, battery, and loads before connection. Their rated voltages should be all 12V,24V or 48V.
n Make sure that connections between positive and negative poles of Solar panels, Battery and Loads are correct.
n The diameter of connecting cable must be match with the requirements of the current. The diameter should not be too short, in order to prevent cable from
heating which lowers output power.
n The rated current of loads must be smaller than the controller’s.
n Components of system must be correctly and firmly connected to guarantee the controller works well.
2. Features
C2430 / C2460 / C4860 solar charge controller is controlled by CPU, with a perfect SOC management function, they are able to control the charge current and decide whether to
supply power to the loads according to the voltage of battery. The product has the following features:
l It has charging and discharging functions at the same time
l Always keep the battery on full voltage condition.
l Prevent the battery from over-charging.
l Prevent the battery from over-discharging.
l Prevent the battery from reverse charging to solar panels during nights.
l Reverse Polarity Protection for Battery
l Reverse Polarity Protection for Solar panels
l The loads’ current exceeds the rated current of the controller, it will activate the protection mode and lock up, the LCD display shows “Overload”.
l Short circuit of loads, the controller will activate the protection mode and lock up, the LCD display shows “Short circuit”.
l Low battery voltage, the controller will cut off the loads and LCD shows “Battery Low”. Recover to nornal voltage and then loads auto active
l Thunder protection
l LCD display shows the voltage of battery ,charging current and loads’ current in turn by every 5 seconds in condition of working well of solar controller.
l The controller can store the charging current data and discharging current data of the battery.
l When starts up, the controller will self-setup the charging-off voltage, the load-off voltage and the load-on voltage according to the voltage of battery. These default parameters bring into effect in the standard environment temperature ( 25℃).
l The controller will automatically compensate the temperature of the charging voltage according to the changes of the ambient temperature
l The charge-off voltage, load-off voltage and load-on voltage could be settled according to user’s requirement.
l To prevent battery from over discharging, the controller will automatically control the lowest load-off voltage of the load, 12V,24V and 48V should no less than 10V,20V and 40V respectively.
l To recover the default parameters, please keep pressing the button “Menu” for more than 5 seconds.
3. Connection
There are 6 connection ports with marks which will help you connecting.
Caution!
l Do not use the lamplight shine solar panels to generate electricity (The lamplight intensity is weak )
l Don’t replace the solar panel with DC power supply in case of
troubles to solar controller.
l Do connect the solar controller with the battery first, and have
the solar panel connected.
l Don’t reverse electrodes (the positive and negative poles) of the
Solar panels, Battery and Loads.
l Match a suitable cable according to the current. Don’t choose a
too small diameter. (we suggest: cable diameter ≥4mm2(C2430)
≥6 mm2(C2460), ≥12mm2(C4860)
4. Indicator Light
The controller has a three colors battery power indicator LED light, a green load indicator LED light, and a red charging indicator LED light. The red indicator LED light (CHARGE)
will light when the batteries are being charged through the solar panel. The green LOAD LED will light when the load is turned on. The three colors battery power indicator light will be red
if the battery voltage is low, orange during normal working range and green for a fully charged battery.

7. Trouble Shooting
Phenomenon：Green light goes out, the loads stops working, and LCD shows Battery low
Reason：Low voltage of battery
Solution A: Cut off the loads and restart the controller by pressing Button RESET After the battery finish charging, reconnect the loads.
Solution B: Increase solar panel’s power or change battery. When there is something trouble while charging the battery, increase solar panel’s power or change battery.
Phenomenon ：Green light goes out, the loads stops working, and LCD shows Over load
Reason：Overload
Solution： Reduce the quantity of loads and then press Button Reset
Phenomenon：Green light goes out, the loads stops working, and LCD shows Short circuit
Reason：The loads Short circuited
Solution：Eliminate the malfunction and then press Button Reset
Phenomenon：Green LED is on ---------------- Loads are normally working
Phenomenon：Red LED is on -----------------Battery is fast charging
Phenomenon：Red LED is flickering---Battery is charging in constant voltage (or floating) condition.
Trouble：Red LED goes out
Reason：Out of power
Solution：It is common during the night. If it doesn’t charge for a long time, please carefully check the connection of solar panels, controller and battery to avoid loose-connection or disconnection.
