Key Features and Benefits
• Microcontroller digital accuracy
• Fully automatic operation
• Ten field adjustable lighting control options
• Special on/off/on lighting functions
• Manual test capability
• LVD override protection
• Detects day and night using the PV array
• Suitable for all 12/24 Vdc lamps
• Sealed/Flooded battery select

Unique Lighting Control Features
Using solar array voltage to determine day and night, it provides 10 different lighting control options.
By measuring the length of the night, ON/OFF/ON options provide the capability to turn on the light at sunset, turn off the light after 3 to 6 hours, and then turn on the light again for 1 or 2 hours before sunrise.
The length of the night is calculated by taking a moving 4 night average, and thus automatically adjusts for seasonal changes in the length of the night.
The test button helps the installer by blinking the red LED to confirm correct selection of lighting control option, and also turns on the light for 5 minutes to verify that the light is operating correctly.
Timer accuracy is within 2 seconds.
available in 10A or 20A, and at 12VDC or 24VDC
For solar arrays greater than 20A
Our solar controllers are designed for solar home system, ideal for rural electrification systems, and many advantages compared to other controllers:
Low Cost
Solar controller has specifically designed to meet the needs of the rural electrification market. The low cost resulted from using the latest electronic technology and high volume manufacturing.
High Reliability
We are manufacturer of solar charge controllers, the products are designed for high quality and high reliability. The controller has a low failure rate and will last a long time, and got very good feedback from customers until now.
Electronic protections
The solar controllers are built-in electronic fused that do not require replacements.
Easy to use
1. Battery State-of-Charge display.
2. Acoustic load disconnect pre-warning. Controller 1
3. PWM-regulation (series type) controller
4. Boost, Equalize and Float charging, also for VRLA. Controller
5. Automatic 12/24 Volt detection.
6. Integrated temperature compensation
7. Large terminals (up to 16mm2 wire size).
8. SOC and voltage controlled LVD.
9. Fully electronically protected.
