INTRODUCTION
- DISPLAY INTERFACE:
| No. | Icon | Function description |
| 1 |  | Indicate PV/DC input voltage |
|
2 |  | Indicate the setting programs or warning and fault codes (When the product runs normally: This icon rotates clockwise and parameters display one by one through manually pressing “UP” and “Down” button; when the product fails, display the fault codes.) |
| 3 |  | Indicate battery voltage, charging current, charging stage (Bulk charge-BUL, Constant voltage-ABS, Floating-FUL, No charging-NO) |
| 4 |
| Indicate battery capacity bar, it is displayed only when the battery is connected. It is dynamically displayed when charging. |
| 5 |  | Indicate the input status. When PV / DC is connected, it’s corresponding icons are displayed. |
| 6 | AGM | Battery type: AGM,WET, GEL, Lithium, Custom Program. The corresponding icon will flash when setup battery type. |
| 7 | Priority | Ignition enable (Priority): The word is only displayed when the ignition terminal available |
- MENU/SAVE: Setting, enter and save button
- ESC/NEXT: Set and exit the menu interface, fixed display / circular display switching
- UP: Adjust the parameter (increase), view and restore fixed display data, force output on
- DOWN: Adjust the parameter(decrease),view and restore fixed display data, force output off
Note: The external LCD display operation is same.
- Long press button ‘MENU/SAVE’ for 5s to enter the interface, ‘2’ and ‘3’ flash and display the data, ‘2’ display the setting code; Press ‘UP’, ‘DOWN’ to set parameters, then press ‘SET’ to save.
- Press ‘ESC/NEXT’ to cancel the data adjustment and enter into next setting surface.
- Long press the ESC/NEXT’ for 5S, exit the setting surface to main surface. More than 10s without any operation, the interface will automatically return to the main interface.
- When these is no fault, display backlight close automatically after 30s; when there is a fault or press the button, the display lights.
- When DC input is working, press “ESC/NEXT” to display by following data: input DC voltage/output charging voltage → input DC voltage/output charging current → input DC voltage/output charging status → input solar voltage/output charging voltage → input solar voltage/output charging current → input solar voltage/output charging status → back to step 1.
- When solar input is working, press”ESC/NEXT” to display by following data: input DC voltage/output charging voltage → input DC voltage/output charging current → input DC voltage/output charging status→ input solar voltage/output charging voltage→input solar voltage/output charging current → input solar voltage/output charging status→back to step 1.
- Press ‘UP’ and ‘DOWN’ for 5s, background flash three times, data will recover to factory set.
- The main LCD and the external LCD can both display (the external LCD supports hot swapping) and set the parameters, but only one can operate in the meantime(for example, when main one is setting, the external LCD will flashes to indicate that the main LCD is working )

CHARGING TEST
- When the ignition terminal is not enabled (ignition terminal have no voltage), PV has priority. The battery is normally connected. Under normal PV conditions, the battery is charged through the PV (charging voltage and current are based on product settings). If PV fails, stop charging. After the PV is restored, the battery is automatically switched to PV, if it is not normal, stop charging.
When the ignition terminal is enabled (10V<Ignition port voltage <15VDC), DC has priority. The battery is connected normally. Under normal DC conditions, the battery is charged through DC (charging voltage and current are based on product settings). If the DC fails (PV is normal), the battery is automatically transferred to the PV to charge the battery. When the DC is restored, the battery is automatically switched back To DC, if it is not normal, stop charging.
Fan control:
- OPEN: Internal temperature >45℃ or Current>30% Setting charge current
- CLOSED: Internal temperature<35℃ and current< 20% setting charge current.
Internal or external temperature reach the protection value, stop charging; Auto. Recover when temperature is normal
Note:
- Internal temp. protection>65℃;External temp. protection <55℃
- External temp. protection >60℃;Internal temp. protection<50℃, External compensation -3mv.℃
