Q: Can the BMS alarm function be muted temporarily?
A: No, the alarm is critical for safety and cannot be disabled; resolve the triggered issue instead.
Q: What’s the maximum discharge current supported?
A: Dependent on BMS specs; refer to the manual for continuous and peak current limits.
Q: Does the storage history function track cycle counts?
A: Yes, it records charge/discharge cycles and performance data for maintenance planning.
Q: Is the battery compatible with third-party inverters?
A: Compatible with most inverters via BMS communication; confirm voltage/current matching first.
Q: How does the BMS handle prolonged low-temperature storage?
A: It activates low-temperature protection to prevent self-discharge below safe levels during storage.
