Q&A      

             
Maintenance Tips  

• Use correct battery type: Designed for 24V LiFePO₄ marine batteries only—avoid lead-acid or mismatched chemistries.
• Stable power input: Connect to 100–240V AC with proper grounding to prevent voltage instability or fault triggers.
• Avoid heat buildup: Operate in ventilated areas; charger auto-reduces or shuts down if overheating occurs.
• Protect from water exposure: Even marine-grade IP68 units should not be pressure-washed or submerged connectors exposed.
• Check connections regularly: Inspect DC terminals for looseness, corrosion, or salt deposits before and after use.
• Do not disconnect mid-cycle: Allow full automatic shutdown to prevent BMS/charger communication errors.
• Keep firmware/indicator awareness: Watch LED status codes for over-voltage, reverse polarity, or temperature faults.
• Cable safety matters: Use correctly sized marine-grade wiring to avoid heat buildup or voltage drop during high-current charging.
• Storage care: Store charger dry, dust-free, and unplugged when not in use for long periods.
• Periodic cleaning: Light dust removal every 3–6 months improves cooling efficiency and longevity.
