Cabinet: The small or large integrated cabinet can be used as required. Temperature control mode: The natural-ventilation unit, heat exchanger, and air conditioner can be combined flexibly. Local integration and purchase Non-core components such as the soundproof canopy, fuel tank, cabinet, engine, and generator can be locally purchased. High integration and rapid installation Requires three cabinets for a new site and one cabinet for a modernized site. Allows SSUs and power supply units (PSUs) to be installed together with high density and efficiency, reducing the equipment volume and floor area. Site sharing and electricity selling Allows four sites to share the PowerCube 1000, allows electricity bills to be settled based on site, and allows amount of electricity to be remotely recorded. System intelligence, which reduces maintenance workloads and lowers maintenance costs Provides a long maintenance interval, extends the interval of replacing the air filter, diesel fuel filter, and engine oil filter, automatically adds fuel, diagnoses the state of health (SOH), uses a theft prevention design, and offers an element management system (EMS) for centralized management, which reduces maintenance workloads and costs and lowers the requirements for skills of maintenance personnel. Value-added intelligent management Provides value added features such as service management, asset management, operation and maintenance management, recording of amount and fee of electricity, fuel theft prevention design, and fuel adding warning.

Question What do the five subsystems consist of? What are their functions? What are the differences between SCBs, DCBs, FCBs? What are the heat dissipation capacities of the ECS30, small integrated cabinet, and large integrated cabinet?

4.1 Working Principles of the Solar-D.G. Hybrid Power System
When the sunshine is sufficient In rainy days or when the sunshine is insufficient When the sunshine is sufficient, solar energies supply power to the loads and storage batteries. In rainy days or when the sunshine is insufficient, do not charge storage batteries if the solar energy meets load requirements. If the solar energy does not meet requirements, discharge batteries. In rainy days and at night, discharge the storage batteries. During D.G. startup, if the storage battery voltage is lower than the preset value, the D.G. starts until storage batteries are fully charged. If sunshine is available during the process, the ECC500 will deliver a voltage adjustment command to the SSU and PSU and adjust the output voltage of the SSU to 1 V higher than the output voltage of the PSU. This helps to prioritize solar energies and reduce D.G. operation. When the D.G. is working In rainy days or at night

6.5.2 Acceptance Methods Acceptance Process Perform acceptance in the following sequence: PowerCube entire system installation acceptance -> acceptance before system power-on -> PSU installation acceptance -> PMU installation acceptance -> PDU installation acceptance -> battery string installation acceptance -> parameter setting acceptance -> system functions and performance acceptance. Typically, acceptance is performed by following the procedure described above. After acceptance is complete, customers should confirm the acceptance results. Method For such projects as entire PowerCube installation, Huawei must perform the acceptance with customer representatives and the customer representatives must sign on the acceptance manual after the project passes the acceptance. Use tools such as a multimeter during acceptance for parameter settings and system performance. Record related data and submit it to customer representatives for signature.

6.5 Delivery Points-Acceptance
6.5.3 Acceptance Criteria Project and customer requirements Generally, a project has specific requirements for the equalized charging voltage, float voltage, battery capacity, and power-off parameters. Write these parameters in the acceptance manual and take them as acceptance criteria. For such projects as appearance and power cable management, perform the acceptance with customers. Customers should sign on the acceptance manual after the project passes the acceptance. Content that is not specified in the project As for content that is not specified in the project, perform the acceptance according to product acceptance criteria. For details, see the acceptance manual.

Power-on items acceptance checklist
6.5 Delivery Points-Acceptance 6.6.4 Example: ICC Acceptance Checklist NO. Item Result Remark T04 Power-on items acceptance checklist T04-01 Whether all equipment could power-on and work normally.  Y  N All devices should power-on and work normally. T04-02 Whether the ATU could switch from Mains and D.G when battery capacity less than DOD. 1. When Mains recovery, then OFF DG; 2. When Mains off, then ON DG. T04-03 Whether the D.G and Battery could provide the power supply follow the logical management. When battery capacity less than DOD, then ON DG T04-04 Whether the DC output voltage of rectifier is accord with the ECC500, and the voltage value is normal. Measure the DC voltage of bus bar with multi-meter and check if the value is accord with ECC500. T04-05 Whether the communication between ECC500 and the network management server is normal (Scenario with OMU only). The communication between ECC500 and the network management server should be normal. T04-06 Whether the communication between ECC500 and sub equipment (etc.PSU, SSU, DG-SU or AMF) is normal. The communication between ECC500 and sub equipment should be normal. We can check the software version of all sub equipment in the WEB or LCD of ECC500 T04-07 Whether all the parameters of ECC500 is accord with the actual requirement. All the parameters that set in the ECC500 is accord with the actual requirement. for example: battery capacity T05 Parameter and Alarm information items acceptance checklist T05-01 Whether the battery parameter of ECC500 is accord with the battery. The battery capacity, current charge limit and other parameters is right T05-02 Whether the battery current is accord with the ECC500 The battery current value is accord with ECC500. And the current value is right T05-03 Whether the Solar input current is accord with the ECC500 The solar input current value should accord with ECC500. And the value is right T05-04 Whether the Solar input voltage is accord with the ECC500 The solar input voltage value should accord with ECC500. And the value is right T05-05 Whether the DC voltage is accord with the ECC500 The DC voltage value should accord with ECC500. And the value is right T05-06 Whether the AC input voltage is accord with the ECC500. And the value is normal. The AC voltage value is accord with ECC500. And the value is right. T05-07 Whether the ECC500 could get the correct alarm information If some alarm information generate, it should be display by ECC500. For example: battery voltage high, fuel level low

Summary This training session introduces PowerCube 1000 in terms of its composition, working principles, main parameters, application scenarios, maintenance, commissioning, and delivery points. It aims to provide guidelines for engineers to perform site designs, install, maintain, and troubleshoot the PowerCube 1000, and perform system tests.
