System Charging & Management
| Feature | Description |
|---|---|
| Dual Battery Charging | The included 10A charge controller independently charges and protects two 12V batteries, ideal for systems requiring separate power banks (e.g., leisure and starter batteries in a vehicle). |
| PWM Technology | Utilises Pulse Width Modulation for efficient charging, which increases charge acceptance and helps extend battery lifespan. It can also recover some lost battery capacity. |
| Automatic Voltage Selection | The controller automatically detects and adapts to either 12V or 24V system voltage, offering flexibility for different battery bank configurations. |
| Temperature Compensation | A built-in temperature sensor optimises charging parameters based on ambient temperature (-30mV/C/12V), ensuring safe and efficient charging. An external remote temperature sensor is optional. |
Typical Applications
| Application | Description |
|---|---|
| Camper Vans & Motorhomes | Provides reliable power for leisure batteries, lighting, appliances, and onboard electronics during travel and stationary use. |
| Boats & Yachts | Maintains charge for marine batteries, navigation systems, and cabin amenities, ensuring power independence on the water. |
| Off-Grid Sheds & Workshops | Powers lighting, small tools, and other electrical needs in remote locations without grid access. |
| Remote Monitoring & Telecommunications | Ensures continuous power supply for critical equipment such as security cameras or weather stations where grid access is limited. |
Built-In Protection Functions
The 10A dual battery solar charge controller is equipped with multiple protective functions to ensure system safety and longevity. These include: Overcharge Protection • Discharge Protection • Short Circuit Protection • Overload Protection • Battery Reverse Polarity Protection • Stopping Reverse Current at Night.
Common Questions
What is included in this solar kit?
This kit includes a 120W 12V monocrystalline solar panel with 5m of pre-attached solar cable and MC4 connectors, along with a 10A 12V/24V dual battery PWM solar charge controller.
Are mounting accessories and battery cables included?
No, mounting accessories and battery cables are not included with this kit. These items must be purchased separately to suit your specific installation requirements.
Can this kit charge both 12V and 24V batteries?
The charge controller automatically detects and works with both 12V and 24V battery systems. However, the 120W solar panel is primarily designed for 12V systems and will charge two 12V batteries independently.
Is the charge controller waterproof?
No, the charge controller is not waterproof and must be mounted indoors or in a protected, dry environment, away from moisture and direct sunlight.
Installation Notes
- Ensure the solar panel is mounted securely in a location with maximum sun exposure, free from shading.
- The included 5m solar cable can be connected directly to the charge controller; MC4 connectors can be cut off if direct wiring is preferred.
- Mount the 10A dual battery charge controller indoors in a dry, well-ventilated area, away from direct sunlight and moisture.
- Carefully follow the detailed user manual provided with the charge controller for correct wiring and setup procedures.
- Consider purchasing appropriate mounting brackets and battery cables separately to complete your installation.
Before You Buy
- Verify your total power requirements to ensure the 120W panel meets your energy needs for charging two 12V batteries.
- Confirm the physical dimensions of the solar panel (100.5 x 67 x 3.5 cm) fit your intended mounting location.
- Ensure you have suitable battery cables and mounting hardware, as these are not supplied with the kit.
- Understand that the charge controller is not waterproof and requires indoor installation.
- Review the charge controller's specifications to ensure compatibility with your specific battery types and system voltage (12V/24V auto-detection).
Please verify all specifications and compatibility requirements before purchase. Product specifications are subject to change by the manufacturer. This product is covered by a 1-year warranty from Photonic Universe for the charge controller and workmanship for the solar panel, with a 10-year 90% and 25-year 80% power output guarantee for solar cells.
