45A Solar Panel Charge Controller MPPT, Solar Battery Regulator 12v 24v 36v 48v DC Input, Parameter Adjustable LCD Display Solar Panel Regulator fit for Gel Sealed Flooded Lithium Battery

• 【Universal Voltage Auto-Detection System】Automatically identifies 12V/24V/36V/48V DC systems (compatible with Lead Acid/Gel/AGM batteries), supporting plug-and-play connectivity for mainstream energy storage batteries. Features intelligent lithium battery voltage matching, seamlessly integrating with LiFePO4/NMC battery management systems for precise compatibility.
• 【Comprehensive Protection】Combines triple-circuit protection (hardware) + triple-software safeguards, including reverse polarity/overcharge/over-discharge/overload/short-circuit/reverse current protection. Integrated self-diagnostic system triggers automatic power cutoff and audible alarms during abnormalities, with IP67 waterproof certification for robust environmental resistance.
• 【Adaptive Multi-Stage Charging】4-stage charging (Bulk/Absorption/Float/Equalization) optimizes deep maintenance for lead-acid batteries, while 2-stage fast charging (Bulk/Absorption) enhances lithium battery cycle life. Includes lithium reactivation function to restore deeply discharged 0V lithium batteries to rechargeable status.
• 【Smart Monitoring Interface】Equipped with an LCD status display for real-time monitoring of PV input voltage, battery charging phases, error codes, and 18+ operational parameters. Delivers intuitive system status visualization for simplified management.
