Q1: Is the installation complicated? What conditions are required?
A: It can be installed in factory areas, distribution rooms and open outdoor spaces. Only flat hardened ground, 3-phase 380V power supply, good ventilation and reserved heat dissipation space are required; no complex infrastructure needed.
Q2: Can it be used for both on-grid and off-grid?
A: Supports on-grid / off-grid dual mode; it automatically switches to emergency power supply when power fails.
Q3: Is it compatible with photovoltaic power generation?
A: Fully compatible. It can store surplus PV power for self-consumption in daytime and reduce grid power consumption.
Q4: Can it work in high and low temperature environments?
A: Applicable temperature range:
Discharge: -20℃ ~ 55℃
Charge: 0℃ ~ 55℃
0℃ ~ -20℃: Only discharge allowed, charging is prohibited (low-temperature charging will damage the battery and shorten service life).
Below -20℃: The system will activate automatic protection and shut down, unavailable for use.
Q5: Does it require daily maintenance?
A: Maintenance-free for daily use. Only regular dust cleaning and circuit inspection are needed, with extremely low operation and maintenance cost。
