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.
