Q1: Does it require professional installation?
A: Yes. Adopted modular stackable design with standardized interfaces. It can be installed quickly by ordinary professional technicians without complicated disassembly or modification.
Non-professionals are not recommended to wire and power on by themselves to ensure electrical safety and system stability.
Q2: How many units can be stacked at most?
A: It supports series connection for higher voltage and parallel connection for larger capacity. Multiple units can be cascaded and stacked to match high-voltage inverter networking. It can flexibly form energy storage systems from tens to hundreds of kWh without line modification for capacity expansion.
Q3: Can it work in high and low temperature environments?
A: It adapts to wide temperature conditions.
Charging temperature: 0℃～55℃; Discharging temperature: -20℃～60℃.
Built-in intelligent temperature control, low-temperature cell protection and high-temperature power reduction function. It operates stably in extreme cold and hot environments, suitable for mountainous areas, construction sites, rural areas, islands and other complex climate scenarios.
Q4: Is daily maintenance required?
A: No frequent professional maintenance needed. Regular simple inspection is enough:
Keep vents unblocked and dust-free for good heat dissipation;
Check terminals for looseness and corrosion;
Monitor SOC, temperature and alarm records via APP or display screen;
Check installation firmness and sealing regularly.
