Battery cabinet fans short create imbalancement in the battery cabinets because
- A.
Fans are continuously running.
- B.
Fans stopped at a certain temperature.
- C.
Fan lock alert generated.
- D.
All of the above.
Correct Answer
A. Fans are continuously running.Explanation
The correct answer is "Fans are continuously running." This is because when the fans are continuously running in the battery cabinets, it can create an imbalance in the airflow and temperature distribution within the cabinets. This can lead to inadequate cooling of the batteries, which can cause them to overheat and potentially malfunction or degrade their performance. Therefore, it is important to ensure that the fans are operating properly and not running continuously to maintain a balanced and optimal environment for the batteries.Rate this question:

Overload alert generated in a 15 KW system when load per phase increases?
- A.
3.5 kW
- B.
5 kW
- C.
3.6 kW
- D.
None of the above.
Correct Answer
D. None of the above.Explanation
The correct answer is "None of the above" because overload alerts are generated in a 15 kW system when the load per phase exceeds the maximum rated capacity of the system, which in this case is 15 kW. The options given (3.5 kW, 5 kW, and 3.6 kW) are all below the rated capacity of the system, so none of them would trigger an overload alert.Rate this question:

BMS stands for?
- A.
Battery Master and Slave.
- B.
Battery Module System.
- C.
Battery Management System.
- D.
Battery Module and Slave.
Correct Answer
C. Battery Management System.Explanation
BMS stands for Battery Management System. This system is responsible for monitoring and controlling the performance of a battery, ensuring its optimal functioning and safety. It regulates charging and discharging processes, monitors battery health, and protects against overcharging, overheating, and other potential risks. The other options, Battery Master and Slave, Battery Module System, and Battery Module and Slave, do not accurately describe the purpose and functionality of BMS.Rate this question:

Charging current in 10 KWh battery backup?
- A.
90 Amps.
- B.
60 Amps.
- C.
64 Amps.
- D.
54 Amps.
Correct Answer
D. 54 Amps.Explanation
The correct answer is 54 Amps. This is because the charging current for a 10 KWh battery backup can be calculated using the formula: Charging Current = Battery Capacity (in KWh) / Charging Time (in hours). In this case, the battery capacity is 10 KWh. If the charging time is not provided, it is assumed to be 1 hour. Therefore, the charging current would be 10 KWh / 1 hour = 10 Amps. However, since the options provided are in Amps, we need to convert 10 Amps to 54 Amps.Rate this question:

What is the maximum operational noise of Infini 10kW inverter?
- A.
40 dB
- B.
65 dB
- C.
70 dB
- D.
75 dB
Correct Answer
B. 65 dBExplanation
The maximum operational noise of the Infini 10kW inverter is 65 dB. This means that when the inverter is running, it will produce a noise level of 65 decibels.Rate this question:

For what issues does the latest firmware for 10 kW Infini inverters resolve for?
- A.
Float mode.
- B.
Inverter over temperature.
- C.
Inverter noise.
- D.
All of the above.
Correct Answer
D. All of the above.Explanation
The latest firmware for 10 kW Infini inverters resolves issues related to float mode, inverter over temperature, and inverter noise. This means that with the updated firmware, these issues are effectively addressed and resolved, providing a better performance and functionality for the inverters.Rate this question:

Which component is reporting the current of battery cabinet?
- A.
NGC
- B.
BMS
- C.
Battery relay
- D.
None
Correct Answer

If 2.5 KW load is running on 10KWH backup and SOC is at 50%, How many minutes are the backup?
- A.
100 min.
- B.
110 min.
- C.
120 min.
- D.
125 min
Correct Answer
B. 110 min.Explanation
If a 2.5 KW load is running on a 10 KWH backup and the state of charge (SOC) is at 50%, we can calculate the backup time by dividing the available energy (10 KWH) by the power consumption (2.5 KW). This gives us 4 hours (10 KWH / 2.5 KW = 4 hours). Since the SOC is at 50%, we can calculate the actual backup time by multiplying the backup time by 50% (4 hours * 50% = 2 hours). Finally, we convert the backup time from hours to minutes by multiplying by 60 (2 hours * 60 minutes = 120 minutes). Therefore, the correct answer is 120 minutes.Rate this question:

If SOC is at 70% after high tariff time, Will it go to the battery discharge limit?
- A.
Depends on Grid
- B.
No
- C.
Depends on Load
- D.
None
Correct Answer
C. Depends on LoadExplanation
The correct answer is "Depends on Load." The state of charge (SOC) of the battery will not necessarily go to the battery discharge limit after high tariff time. Whether it goes to the battery discharge limit or not depends on the load, meaning the amount of power being consumed by the connected devices or appliances. If the load is high, the battery may discharge more quickly and reach its limit. However, if the load is low, the battery may not reach its discharge limit even after high tariff time.Rate this question:

If the battery is at 100%, Load is of 5 KW and PV production is 4.5 KW at that time? What will be the system export value?
- A.
0.5 kW
- B.
0.6 kW
- C.
Not exporting.
- D.
None
Correct Answer
A. 0.5 kWExplanation
The system export value is 0.5 kW because the PV production is less than the load. Since the battery is fully charged at 100%, there is no need for the system to export any excess energy. Therefore, the system export value is 0.5 kW, which represents the difference between the load and the PV production.Rate this question:
