solaV LS 1012 EPD LS-EPD-Series PWM Charge Controller
General Information
LS-EPD series solar charge controller adopts the most advanced digital technique and operates fully automatically. It is ideal for extreme environments with corrosion, dust, water etc and has various unique functions：
- Electronic protection: Over charging, over discharging, overload, short circuit and reverse protection of solar module
- High efficient Series PWM charging, increase the battery lifetime and improve the solar system performance
- Widely used, automatically recognize day/night
- Battery LED indicate battery status
- Industrial design, wide application range
- Digital tube menu, only one key solve all setting simply
- Intelligent timer function with 1～13 hours option
- IP67 protection

Mounting
- Connect components to the charge controller in the sequence as shown above picture and pay much attention to the “+” and “-”. Always power the battery firstly.
- After power the battery, check the battery indicator on the controller, it will be green. If it’s not green, please refer to chapter 4.
- The battery fuse should be installed as close to battery as possible. The suggested distance is within 150mm.
Indicators Description and Operation
Indicator Status Description
| Charging Status LED indicator | Green | On Solid | Normal |
|---|---|---|---|
| Green | Fast Flashing | Over voltage |
Battery Status LED indicator
| Green| On Solid| Normal
Green| Slowly Flashing| Full
Orange| On Solid| Under voltage
Red| On Solid| Over discharged
Radix Point of Digital tube
(Load indicator)
| Red| On Solid| Load ON
Red| Slowly Flashing| Over Load
Red| Fast Flashing| Short Circuit
Operation
Digital tube Key
The digital tube display the load work mode, please refer to the
correspondence table of Load Work Mode & LED digital tube value. Pressing the
key to configure the parameter, please refer to the below configuration
method:
- After Powering on, disconnect the PV or connect the PV(Voltage<5V) , the light of the digital tube point go on; Connect the PV(Voltage>6V) ,the light of the digital tube point go off.
- The key can be used to operate switching on/off the load (Manual control) or clearing the faults
- Keeping pressing the button over 5S, It will go to the parameter in browsing mode which can cycle through the parameter item by clicking the button ,after the light of the digital tube point going on.
- After the digital tube displaying the value what you want to configure, releasing the key and waiting 15S, Digital Tube stop flashing, then the configuration is successful.
Load mode
Manual Control： Control the load via the button.
Note: In the mode of Light ON/OFF and Light ON/Timer, the Load is turned on after 10Min. delay.
Test Mode (Default)：Test Mode is as same as Light Control Mode but no delay.
The correspondence table of Load Work Mode & LED digital tube value
| Value | Working mode | Value | Working mode |
|---|---|---|---|
| 0 | Light ON/OFF | Light ON + 8 hours | |
| 1 | Light ON + 1 hours | Light ON + 9 hours | |
| 2 | Light ON + 2hours | Light ON + 10 hours | |
| 3 | Light ON + 3hours | Light ON + 11 hours | |
| 4 | Light ON + 4 hours | Light ON + 12 hours | |
| 5 | Light ON + 5 hours | Light ON + 13 hours | |
| 6 | Light ON + 6 hours | Manual Control | |
| 7 | Light ON + 7 hours | Test Mode |
Troubleshooting
| Faults | Possible reasons | Troubleshooting |
|---|
Charging LED indicator off during daytime when sunshine falls on PV modules properly| ****
PV array disconnection
| ****
Check that PV and battery wire connections are correct and tight
Charging Status LED indicator fast flashing
| Battery voltage higher than over voltage disconnect voltage| ****
1. Disconnect the solar array and measure the battery voltage whether is too high; 2. Change the controller; 3. Change the battery
Battery LED indicators red color and loads not working| ****
Battery over discharged
| The controller cut off the output automatically. LED indicator will return to green automatically when fully
The radix point of digital tube fast flashing and load not working
|
Short circuit
| Clear short circuit. It is reactivated after delayed 10 seconds for the
first time, If over 1 time，press the key to clear error and the controller
will resume to work after 3s or restart the controller
---|---|---
The radix point of digital tube slowly flashing and load not working
|
Over load
| Please reduce the number of electric equipments.
When load power reaches 1.25-1.5 times, 1.5-2 times and 2 times more than nominal value, controller will automatically close loads in 60 seconds, 5 seconds and 1 second, respectively.
Please press the key to clear error and the controller will resume to work after 3s or restart the controller
