Product Description
off-grid wind solar system charge controller with dump load 3KW
Product Characteristics
- The product can be manufactured in accordance with either JB/T6939.1-2004 industrial standard, GB/T19115.1-2003 national standard or users technical requirements.
- Adopt two sets of control systems, PWM constant pressure system and three-phase load discharging system.
- PWM constant pressure control is 120% of the rated power of the wind turbine generator. In case of exceeding the scope of PWM constant pressure power, the three-phase load discharging will automatically start immediately to ensure safe operation of the overall wind turbine generation system.
- Under the circumstances of decoupling and damage of the battery, the three-phase load discharging will automatically start to avoid the idle run of the wind turbine generator and the occurrence of runaway accident.
- PWM control: Under the conditions of strong or super-strong wind, ensure battery charged by the wind turbine generator under constant voltage and current.
- It has reverse connection, anti-decoupling and damage-resisting protection of the battery.
- Over-charging protection of the battery: When the battery is full (the battery pressure reaching 125% of the rated pressure), the controller will automatically carry out three-phase load discharging to stop charging battery.
- Auto recovery of battery charging: When the battery pressure reduces to 108% of the rated pressure, the three-phase load discharger will stop load discharging to automatically recover battery charging.
- The inside of the controller is equipped with lightening protection device. Contain the transit over voltage penetrating into the wind turbine generator within the voltage scope bearable to the equipment or system or conduct the strong lightening current into the earth to avoid equipment damage posed by lightening impact.
- The big screen LCD display. Clearly present the working status of the wind turbine, solar panel, battery and controller.
- The controller is equipped with manual three-phase load discharging switch; the user may use it according to actual circumstances. When using this switch, the wind turbine generator will forcibly carry out three-phase load discharging.
Intelligent Battery Compatibility
The controller automatically recognizes and supports various battery types, such as Lead Acid, GEL, AGM, and Lithium Iron Phosphate (LiFePO4). This smart compatibility streamlines installation and maximizes battery lifespan, making it highly versatile for both home and small commercial off-grid systems.
Advanced Protection & Management
With integrated overcharge, over-discharge, overload, reverse polarity, and short circuit protections, the charge controller promotes safe and reliable operation. Its microprocessor-controlled management system intelligently balances charging between wind and solar inputs, ensuring optimal performance and security.
Efficient Hybrid Control & Dump Load Integration
Featuring a hybrid PWM and relay control system, the controller maintains efficient charging above 95% with automatic dump load activation to protect batteries from overcharging. This not only improves system efficiency but also reduces maintenance needs through automatic and passive safety features.
FAQs of off-grid wind solar system charge controller with dump load:
Q: How does the controller optimize charging from both solar and wind sources?
A: This charge controller uses a microprocessor-controlled hybrid system (PWM & relay) to seamlessly balance and regulate input from solar panels and wind turbines. It automatically distributes power based on resource availability and battery condition, ensuring maximum charging efficiency and system protection.Q: What types of batteries are compatible with this hybrid charge controller?
A: The controller is designed to support Lead Acid, GEL, AGM, and Lithium Iron Phosphate (LiFePO4) batteries. Its intelligent auto-recognition feature eliminates manual configuration, allowing easy integration with various battery banks to suit different project needs.Q: When should I use the dump load function and how does it work?
A: The dump load function is automatically triggered when the batteries reach full charge, diverting excess energy safely to prevent overcharging. This feature operates without user intervention, protecting battery health and maintaining efficient energy use within the system.Q: Where is the optimal installation location for the charge controller?
A: The controller is designed for wall or surface mounting in indoor or sheltered environments. Ensure the installation area maintains a non-condensing humidity of 095% and ambient temperatures between -20C and +55C to guarantee optimal operation and extend device life.Q: What benefits does the LCD digital screen provide?
A: The built-in LCD digital screen offers clear, real-time monitoring of system parameters including input voltage, output status, load state, and protection alerts. This user-friendly interface enables easier maintenance and enhances system visibility, ensuring youre always informed about your power setup.Q: How does the active fan cooling system enhance reliability?
A: Active fan cooling automatically maintains optimal internal temperature during high-load operation, preventing overheating. Combined with advanced protection circuits and an aluminum alloy housing, this cooling approach ensures long-term reliability and safe, efficient performance.Tell us about your requirement
