Frequently Asked Questions
Max continuous load: 4800W. We recommend ≤4000W for safe use. Peak 200A only for short moment.
Use dedicated lithium battery charger. Cut-off voltage set to 54.75V. DO NOT use lead-acid charger.
BMS protection activated (over-current, low voltage, overheat). Disconnect load and rest 10–30 mins for recovery.
Only identical, same-age batteries can be paralleled. Mixing different batteries is forbidden.
Keep 50%–70% charge. Recharge every 3 months. Store in dry, ventilated place.
ABS case is dustproof, NOT waterproof. Avoid continuous rain or immersion. Use extra waterproof cabinet for outdoor installation.
No short circuit, no disassembly, no heavy impact. Keep ventilation while charging. Avoid fast charging under 0℃.
