12V 10A Solar Charge Controller Dusk to Dawn function for Street Lights PCB only

12 V 10 A Solar Charge Controller with Dusk-to-Dawn Function PCB Board (Bare PCB)

This PCB is designed for building a solar charge controller with battery charging and automatic load control based on ambient light conditions. Performance depends on components used and assembly quality.

Solar Input:

• Supported solar panel power: 10 W to 100 W
• Open circuit voltage (Voc): 17 V to 24 V DC
• Maximum input current: up to 10 A

Charging Configuration:

• Charging method: linear voltage control using op-amp controlled P-channel MOSFET
• Low dropout operation: approximately 0.7 V (depends on components used)
• Charging voltage adjustable based on battery type and configuration

Battery Compatibility:

• Supports 1 Ah to 60 Ah batteries
• Compatible with Lead Acid and Sealed Lead Acid (SLA) batteries
• Can be configured for Ni-Cd and Lithium batteries with appropriate settings and precautions

Load Control (Dusk-to-Dawn):

• LDR-based automatic switching of load
• Uses N-channel MOSFET for load control
• Supports LED load up to approximately 50 W (depends on components used)

• P-channel MOSFET (Q2): IRF9540, IRF4905, IRF5305, IRF9Z24, IRF9Z34
• N-channel MOSFET (Q1): IRF540, IRF3205, IRFZ44, IRFZ48, STP55NF06
• Transistors (Q3, Q4): BC546, BC547, BC548, BC549, BC550
• Op-amp IC (U1): LM358, NE5532, TL072, JRC4558, LM833

Construction:

• Bare PCB (components not included)
• Designed for through-hole components
• Components are commonly available

Configuration:

• Charging voltage and performance depend on component selection and adjustment
• Requires proper installation and wiring for solar panel, battery, and load

Intended Use:

• Solar street light systems with automatic dusk-to-dawn operation
• Battery charging for off-grid solar applications
• DIY solar power and lighting projects
