FAQ
Q: What is the operating temperature range of the battery?
A: Operating temperature -20~50℃ (greater than 45℃ derating), built-in intelligent temperature control system to ensure wide temperature range operation.
Q: Does the battery support off-grid power supply?
A: It supports off-grid power supply, with the optional black start function, and the optional switching device can make the switching time less than 20ms.
Q: How to calculate the maximum charging and discharging power of the system?
A: Power = rated capacity of battery pack × charging/discharging rate (e.g. 1C multiplication rate for 100kWh system is 100kW).
Q: How does the system fault self-test?
A: Self-testing of energy storage system faults can start from the battery system, inverter, monitoring system and other major components. Battery system appearance, voltage and internal resistance check, temperature check; inverter appearance and connection check, operation status check, noise check; monitoring system data display check, communication function check, alarm function check; and other components such as fuse check, lightning protector check, cable and bus bar check. When carrying out self-inspection of energy storage system faults, it should be carried out in strict accordance with relevant operating procedures and safety norms, and for some complicated faults or uncertainties, it is recommended to contact professional technicians for maintenance in time.
Q: How to connect external sensors?
A: Determine the sensor type and interface, select the appropriate cable, connect the sensor to the energy storage system, and configure the communication parameters. If you encounter any complicated or difficult problems during the above processing, you should contact our technicians for further support and assistance.
