PWM Solar Controller: Efficient, Durable, and Safe for Off-Grid Systems
 
Power up your off-grid 12V-24V setup with this robust PWM solar controller. Designed for maximum battery performance, it uses a 3-stage charging algorithm (bulk, absorption, float) to extend battery life, supporting both lead acid (flooded, GEL, AGM) and lithium batteries (Li(LiCoMn)O2, LiFePO4).
 
Key Features:
3-Stage Charging: Efficient PWM charging to boost battery lifespan.
Dual Panel Connection: Connect two solar panels for higher charging efficiency.
Programmable Voltage: Customizable settings for battery protection.
LCD Display & USB Ports: Real-time system view, easy settings, plus USB for device charging.
Built-In Protections: Safeguards against over/under voltage, short circuits, overcharging, and more.
Temperature Compensation: Adjusts charging for temperature changes, enhancing battery life.
Reinforced Design: Durable ABS housing and thicker PCB boards for added durability.
 
Get reliable performance and peace of mind with this solar controller, built for the demands of off-grid applications.
