For 12V-48V battery systems: Connect the battery group first → Set the output voltage → Then connect the solar panels. For 12V systems: Connect solar panels with ≥30V first → Set parameters → Then connect the battery. The controller’s hardware over voltage protection limit is 180V. Ensure sufficient voltage margin during use. The recommended maximum open-circuit voltage for solar panels is below 150V to avoid controller damage. For 12V batteries: Recommended solar panel input voltage is 36V-72V. For 24V batteries: Recommended solar panel input voltage is 41V-125V. For 48V batteries: Recommended solar panel input voltage is 80V-150V. Do not reverse-connect battery terminals. Ensure power is off during installation. Install DC circuit breakers on input/output terminals.
- 【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.
