Product Features
Thank you for choosing our product. This PWM solar charge controller is a device for solar charge regulation and direct current output load control. This device is mainly used in small-sized off-grid solar power systems.
These charge controllers have these features:
- Charging mode available for most common deep-cycle battery types in the market, including AGM (sealed lead acid batteries), GEL, Flooded, and Lithium mode with customized parameters.
- Automatic recognition of 12V/24V battery system for AGM/GEL/Flooded battery.
- 5V 1A USB outlet provides charging for mobile devices.
- Provides multiple load control mode options for light-based, time-based and manually adjusted scenarios.
- Industrial grade design with reverse polarity protection for solar panels, battery and load.
- We provided 2way of installation: flat mount with bracket and flush mount fixture.

Mounting Instruction
This controller can be mounted flush or flat with included bracket at a cool, dry and weather safe location.
Flat Mount with Bracket
- Attach the mounting bracket to the back of the controller using screws.
- Mark the bracket’s mounting holes on the mounting surface.
- Attach the mounting bracket to the mounting surface using screws.
Flush Mount
- Mark the controller’s dimension and mounting holes on the mounting surface.
- Make necessary alterations to ensure the controller fits into the mounting surface snugly. Pre-install wires if needed (turn to next page for instructions).
- Attach the controller to the mounting surface using screws.
Wire Connection Sequences
During installation of your PWM controller, please follow below order of connection:
- Connect the positive battery wire followed by the negative battery wire.
- Make sure your solar panels are fully covered to prevent electrical shock. Connect the positive solar array output wire followed by the negative solar array output wire.
- Connect the DC load wiring to the DC load output (if applicable).

LCD Display Rules & Cycles
Pre start-up display cycle when the MPPT controller turns on, this usually last several seconds while controller detects operating environment.
LCD Screen Display Cycle
- The information pages in the screen will be automatically turning to the next page every 5 seconds and keep lasting. The user also can use up and down keys to cycle through different pages.
- The error code page will be displayed when an error is detected.
Setting Battery Mode
| Abbreviation s | Battery Types | Description |
| FLD | Flooded Battery | Auto-recognition with default parameters set for each type of batteries. |
| SEL | Sealed/AGM Battery | |
| GEL | Gel Battery | |
| LI | Lithium Battery | Customize charge & discharge voltages. |
Advance Battery Settings
In Lithium mode, short press the arrow key again to cycle through each parameter view. Use the load key to adjust parameter value, then long press arrow key to save and exit.
Load Mode Settings
Enter Load SET Mode by pressing the arrow key in Load Mode view only. Short press the arrow key to cycle through load modes before long pressing the arrow key again to save and exit.
| Mode | Definition | Description |
| 0 | Daylight Auto-Control | The PV voltage turns on the load when it is night |
| 1~14 | Daylight On/Timer Off | DC load turns on when daylight is detected. DC load turns off according to timer.
Mode 1 = turn off after 1 hour, etc. |
| 15 | Manual Mode | DC load turns on/off by pressing the load key. |
| 16 | Testing Mode | DC load turns on and off in a quick succession. |
| 17 | Always on | DC Load Stays On |
Error Code Chart
| Code | Error | Description & Quick Troubleshoot |
| E00 | No error | No action needed. |
| E01 | Battery Over-discharged | Battery voltage is too low. DC load will be turned off until battery re-charges to recovery voltage. |
| E02 | Battery Over-voltage | Battery voltage has exceeded controller limit. Check battery bank voltage for compatibility with controller. |
| E04 | Load Short Circuit | DC load short circuit. |
|
E05 |
Load Overload |
DC load power draw exceeds controller capability. Reduce load size or upgrade to a higher load capacity controller. |
|
E06 |
Overheating |
Controller exceeds operating temperature limit. Ensure the controller is placed in a well-ventilated cool, dry place. |
| E08 | Solar Over-amperage | Solar array amperage exceeds controller rated input amperage. Decrease the amperage of solar panels connected to the controller or upgrade to a higher rated controller. |
| E10 | Solar Over-voltage | Solar array voltage exceeds controller rated input voltage. Decrease the voltage of solar panels connected to the controller. |
| E13 | Solar Reverse Polarity | Solar array input wires connected with reverse polarity. Disconnect and re-connect with correct wire polarity. |
| E14 | Battery
Reverse Polarity |
Battery connection wires connected with reverse polarity. Disconnect and re-connect with correct wire polarity. |
Controller Specification
The variable “n” is adopted as a multiplying factor when calculating parameter voltages, the rule for “n” is listed as: if battery system voltage is 12V, n=1; 24V, n=2.
For example, the equalize charge voltage for a 12V FLD (Flooded) battery bank is 14.8V*1=14.8V. The equalizing charge voltage for a 24V FLD (Flooded) battery bank is 14.8V*2=29.6V.
