Installation Guide
Step 1:
Locate a clear sunlit area free from overhanging branches or heavy shade.
Step 2:
Unfold the solar panels, adjust the two supports to a suitable angle.
Step 3:
Always face the front side of solar panels towards the sun. Wipe down the panels with a microfiber cloth to remove any dust or debris.

Wiring
(1) Before connecting the solar charger kit with battery, please MAKE SURE the solar panel surfaces are covered or facing ground, since the correct connection sequence is Battery first, then Loads if any, Solar panels to be connected last.
(2) After powering the regulator, check the Battery LED indicator on the regulator, to be solid green. Otherwise, please refer to section 8.
LED Indicators
(1) Charging and Load Status Indicator
| Indicator | Color | Status | Instruction |
|---|---|---|---|
| Charging status LED indicator | Green | On Solid | Charging |
| Green | OFF | No Charging | |
| Green | Fast Flashing | Battery Over Voltage | |
| Load status LED indicator | Green | On Solid | Load ON |
| Green | OFF | Load OFF | |
| Green | Slowly Flashing | Load over load | |
| Green | Fast Flashing | Load short circuit |
(2) Battery Status Indicator
The battery status is indicated by LED1, LED2, LED3, and LED4. The diagram shows these LEDs and the LVD (Low Voltage Disconnect) indicator.
| LED1 | LED2 | LED3 | LED4 | Battery Status |
|---|---|---|---|---|
| ○ | ○ | ○ | ○ | Under voltage |
| ○ | ○ | ○ | ○ | Over discharge |
| Battery LED indicator status during voltage is up | ||||
| ○ | ○ | ○ | ○ | 12.8V<Ubat<13.4V |
| ○ | ○ | ○ | ○ | 13.4V<Ubat<14.1V |
| ○ | ○ | ○ | ○ | 14.1V<Ubat |
| Battery LED indicator status during voltage is down | ||||
| ○ | ○ | ○ | ○ | 12.8V<Ubat<13.4V |
| ○ | ○ | ○ | ○ | 12.4V<Ubat<12.8V |
| ○ | ○ | ○ | ○ | Ubat<12.4V |
NOTE: "○" LED indicator ON; "×" LED indicator OFF.
6. Setting Operation
(1) Load ON/OFF Setting
When the regulator is powered on, press the button to control the load output. NOTE: The USB will output when the load is on.
(2) Battery Type Setting
Operation:
- Enter setting mode by pressing the button for 5 seconds until the battery status LEDs are flashing.
- Select the desired mode by pressing the button.
- The mode will be saved automatically without any operation for 5 seconds and LED will stop flashing.
Battery Type Indicator
| LED1 | LED2 | LED3 | Battery type |
|---|---|---|---|
| ○ | ○ | ○ | AGM/ Lead Acid (Default) |
| ○ | ○ | ○ | Gel |
| ○ | ○ | ○ | Flooded |
NOTE: "○" LED indicator ON "×" LED indicator OFF
7. Protection
- Battery Over Voltage Protection: When the battery voltage reaches the set point of Over Voltage Disconnect Voltage (OVD), the regulator will stop charging the battery to protect the battery from being over charged.
- Battery Over Discharge Protection: When the battery voltage reaches the set point of Low Voltage Disconnect Voltage (LVD), the regulator will stop discharging the battery to protect the battery from being over discharged.
- Load Overload Protection: Load will be switched off when 1.25 times rated current overload will occur. User has to reduce load appliance, then press the button or repower the regulator.
- Load Short Circuit Protection: Load will be switched off when load short circuit (>3 times rated current) will occur. User has to clear short circuit, then press the button or restart the regulator.
- High Voltage Transients Protection: The regulator is protected against small high voltage transients. In lightning prone areas, additional external suppression is recommended.
8. Troubleshooting
| Faults | Possible reasons | Troubleshooting |
|---|---|---|
| LED Charging indicator turn off during daytime when sunshine falls on PV modules properly | PV array disconnection | Confirm that PV and battery wire connections are correct and tight. |
| No LED indicator | Battery voltage maybe less than 8V | Measure battery voltage with the multi-meter. Min. 8V can start up the regulator. |
| Charging status LED indicator Fast flashing | Battery Over Voltage | Check if battery voltage is higher than OVD, and disconnect the PV. |
| LED1 Fast flashing | Battery over discharged | When the battery voltage is restored to or above LVR point (low voltage reconnect voltage), the load will recover. |
| Load status LED indicator slowly flashing | Load over load | ① Please reduce the number of electric equipments. ② Press the button or repower the regulator. |
| Load status LED indicator fast flashing | Load short circuit | ① Check carefully loads connection, clear the fault. ② Press the button or repower the regulator. |
