Q1: Can this container load bank perform full-step load simulation for generator & energy storage system acceptance test?
A1: Yes. It can simulate steady-state and step-changing resistive load to verify the performance of diesel generators, UPS systems and grid-connected energy storage equipment, to
complete factory and site acceptance without actual real user load.
Q2: What rated voltage systems are available? Does it support 415V Line / 230V Phase, 400V, 6.6kV, 11kV medium voltage options?
A2: Yes. Low voltage version supports 415V (230V phase) / 400V; Medium voltage models including 6.6kV, 11kV are available as customized options. 480V/277V is also optional.
Q3: Can multiple containerized load banks be paralleled together to achieve combined higher total load capacity for large power plant or big data center cluster testing?
A3: Yes. Multiple container units can be synchronized and paralleled. The control system can work together to realize combined large load for multi-generator parallel commissioning
and large-scale power system verification.
Q4: Can the system automatically generate editable acceptance test reports for EPC project handover?
A4: Yes. The system continuously records full test data, and can export editable acceptance test reports in PDF and CSV format for project delivery and client audit.
Q5: Do you provide overseas on-site commissioning, operator training and after-sales technical support? Is remote online commissioning available?
A5: Yes. We supply overseas on-site commissioning, operation training and long-term technical support. Remote online debugging is also available as an alternative solution.
Q6: What is the load adjustment step resolution?
A6: Standard load step resolution is 100kW. Finer adjustable load resolution can be customized as requested.
Q7: Does the equipment support remote monitoring & control via MODBUS TCP/IP or SCADA system connection?
A7: Yes. MODBUS-RTU and MODBUS TCP/IP communication are built-in. It supports remote load setting, real-time power/temperature data reading, and remote alarm monitoring, compatible with customer SCADA platform.
Q8: What is the cooling method of this container load bank? Forced air cooling or liquid cooling?
A8: Forced air cooling is standard configuration. Liquid cooling container version can be customized for high ambient temperature sites or high-density continuous load test requirements.
Q9: What is the maximum continuous running time under full rated load?
A9: It supports 24/7 continuous stable operation at rated full load.
Q10: Can it simulate programmable dynamic load profile, load step up/down, sudden load rejection for UPS switching test, generator transient response and grid fault simulation?
A10: Yes. It supports programmable dynamic load curves, step/ramp load changes and sudden load shedding. It can simulate power failure, UPS transfer switching and generator transient performance test.
Q11: What built-in safety protection functions are equipped? (over-temperature, over-current, over-voltage, under-voltage, emergency stop etc.)
A11: Built-in protections include over-temperature, over-current, over-voltage, under-voltage, fan failure protection, over-frequency /under-frequency protection and emergency stop. It will automatically cut off the load immediately once any alarm is triggered.
Q12: What is your production lead time for standard and customized container load bank models?
A12: Standard low voltage container models: 6–8 weeks. Custom medium voltage, liquid cooling or special design units: 10–16 weeks, final lead time depends on project specifications.
Q13: What electrical and thermal parameters can be recorded and stored during the load test?
A13: Recorded data includes three-phase voltage, three-phase current, active power, reactive power, apparent power, power factor, frequency, cabinet temperature, running time and full alarm event logs.
Q14: Can the container design be customized? Such as container size, internal layout, cable access position, local control cabinet layout.
A14: Yes. Container dimension, cable inlet direction, control panel layout and external interface can be customized to match site installation requirements.
