○ Appearance and interface
○ BMS
Exclusive intelligent BMS with dual cell equalization is equipped,
offering comprehensive protection from overvoltage, undervoltage, overcurrent, short circuit
and extreme temperatures to guarantee safe operation of household and commercial energy storage systems.
Short Circuit Protection
Instant short-circuit cutoff activated with high current trigger value, it auto-resets after 60 seconds if charging current is detected. If short-circuit occurs continuously for 5 times, the system will lock and can only be unlocked by connecting a charger.
Temperature Protection
Cell discharge overheat protection triggers at 55℃, restores operation when cooling down to 50℃;
MOS high-temperature protection cuts off output at 100℃, recovers at 85℃;
Ambient over-temperature protection shuts down the unit at 60℃, resumes when temperature falls to 55℃;
Built-in low-temperature heating module activates below 0℃ during charging to avoid low-temperature cell damage.
