FAQ
Q1: What’s the maximum expandable capacity?
A: Single module is 4.8kWh; supports up to 4 modules in parallel, max 19.2kWh total energy.
Q2: Can it be used outdoors?
A: No, it has an IP20 protection grade, designed exclusively for indoor use—avoid moisture and direct sunlight.
Q3: What communication modes are supported?
A: Standard CAN and RS485; Bluetooth is optional for wireless monitoring.
Q4: What routine maintenance is required?
A: ① Supplementary charging every 6 months; ② Disconnect output if unused long-term (keep 45%-55% SOC); ③ Clean with a dry brush.
Q5: Why is discharge time shorter than expected?
A: Possible causes: low SOC, extreme temperature, overload, or aging. Charge fully, work within 10~35℃, reduce non-essential loads, or contact support.
Q6: Is it compatible with all inverters?
A: Compatible with most mainstream inverters via CAN/RS485; confirm protocol compatibility with our technical team.
Q7: What are the storage requirements?
A: Store indoors (25℃±5℃, RH ≤75%), 45%-55% SOC, ≥2m from heat sources; recharge every 6 months if stored over 90 days.
Q8: What wiring specifications are recommended?
A: Single-module: 1/0 AWG (2000mm) for positive/negative wires; shielded cable for CAN communication. Parallel modules: 1/0 AWG (70mm) for inter-module wiring.
