- Balanced 3-stage PWM charging - Uses a 3-stage PWM charging algorithm (bulk, absorption, float) to charge batteries evenly, reduce imbalance and prevent sulfation. Extends battery life and maintains reliable capacity over time. - Automatic 12 V / 24 V support and flexible load modes - Automatically detects and configures for 12 V or 24 V systems. Offers multiple selectable load working modes so you can match controller behavior to your application (lighting, timed loads, or continuous supply). - Robust protection for safe operation - Built-in safeguards against overcharge, over-discharge (deep discharge) and short circuits to protect the battery and attached loads and to ensure safe, unattended operation. - User-friendly DOT-array LCD and controls - Clear DOT-array LCD presents charging status, battery level and operating mode. Intuitive interface makes setup and mode changes quick and straightforward without specialist tools. Key attributes at a glance - Function: 3-stage PWM charge control, selectable load modes, automatic 12 V / 24 V configuration - Compatibility: Designed for 12 V and 24 V battery systems (suitable for typical lead-acid battery banks) - Performance: Prevents sulfation and cell imbalance; improves battery life and system reliability - Design: Compact controller with DOT-array LCD and user-friendly controls for easy monitoring and configuration - Safety: Overcharge, over-discharge and short-circuit protection for dependable, low-maintenance operation Practical applications - Small solar off-grid systems: Maintain battery health and regulate PV charging for home lighting, small appliances or sensor systems using 12 V or 24 V battery banks. - Recreational vehicles and boats: Provide reliable charging and load control for onboard batteries while preventing sulfation and over-discharge during storage or travel. - Backup power and lighting: Keep stand-by batteries healthy and manage load scheduling for emergency lighting, security systems or telecom equipment. What this product solves - Reduces battery failures and premature replacement by preventing sulfation and imbalance. - Simplifies system setup by automatically selecting 12 V or 24 V operation and offering selectable load modes. - Protects equipment and batteries with essential safety features for safe, long-term use. If you need a compact, reliable charge controller that supports both 12 V and 24 V systems, provides 3-stage PWM charging, clear LCD feedback and essential protection features, this controller delivers practical performance for a wide range of small off-grid, mobile and backup power applications.
