1. Environmental Suitability:
- How does the system perform under the specific climate and weather conditions typical of remote areas in the DRC?
- Is the liquid-cooling system sufficiently effective in maintaining optimal battery temperatures in high-heat environments?
Answer: Currently we are using the third generation of the latest liquid cooling system technology, suitable for extreme weather, even if the weather is 55 degrees Celsius can still control the temperature of the battery in the appropriate range, compared with air-cooled systems have the following advantages：
1. Close to the heat source for efficient cooling.
2. Liquid cooling has low noise, saves its own power consumption and is environmentally friendly.
3. Reduced use of mechanical parts such as fans, low failure rate.
2. System Scalability and Flexibility:
- Can the system be easily scaled to accommodate fluctuating energy needs?
- How does the integration of additional units work with the existing setup?
Answer: Currently 115kwh and 215kwh are the standard capacity cabinets in the industry. One of the biggest advantage of this system is its scalability. For example, when a customer needs a 1Mwh system, 5 energy storage units can be parallel together to meet the demand, which allows for batch, standardized production and flexible configuration options.
3. Safety and Reliability:
- Could you provide more details on the effectiveness of the NOVEC 1230/FM200 fire suppression system?
Answer: Novec 1230 and FM-200, they have been the mainstream of fire suppression systems for over 20 years.Both Novec 1230 and FM-200 can extinguish Class A, B and C fires, they are non-conductive and will not short out electronic equipment or heat shock delicate circuits.
Gas fire suppression systems pose no health risks, they are highly effective, non-conductive and leave no residue when they evaporate. Although gaseous fire suppression systems are rarely required by building or fire codes, businesses and other institutions and organisations are increasingly turning to clean agent fire suppression as a more effective way of protecting assets such as: Computer systems including servers and other electronic components. Telecommunication systems Record/document storage repositories and libraries - any paper that must be protected Digital data storage repositories Cultural assets such as historic buildings, museums, and works of art Flammable liquids Storage.
- What measures are in place to prevent or manage thermal runaway, and how does the system ensure safety against overcurrent and arc events?
Answer: According to the past global energy storage thermal runaway research analysis, its main reasons mostly happens after the failure of the core combustible gases can not be discharged in a timely manner and triggered by thermal runaway, so the container ventilation system, cooling is particularly important.
We take the following measures:
1. Inserting cold water plates between the electric cores to block the heat spreading after the thermal runaway of the electric cores.
2. Fire extinguishing device, when a single core thermal runaway can quickly react to start the fire extinguishing device.
3. Ventilation and explosion-proof.
We have installed a gas monitoring and ventilation system, which is very effective in reducing this risk. When a certain level of flammable gas is detected (i.e. 25% of the LFL), the system will activate exhaust ventilation.
4. Maintenance and Operation:
- What regular maintenance is required for this system, particularly in a remote and potentially challenging environment?
- How is system health monitored, and what support is available for maintenance and troubleshooting?
Routine maintenance can be carried out according to our regular maintenance manual and we are equipped with visualization and monitoring.

5. Compatibility with Local Infrastructure:
- Is there any necessary modification or additional equipment required to integrate this system with the existing grid infrastructure in the DRC?
- How does the system cope with grid instability and fluctuations?
Currently the 215kwh system can be directly connected to the grid, can through the grid, photovoltaic, diesel engine to the battery charging does not need to add other equipment, if it is needed to grid-connected to sell electricity, it need to increase the grid-connected inverter to achieve the sale of electricity to earn income.
6. Energy Efficiency and Performance:
- What are the expected efficiency levels under various operating conditions, especially in high temperatures?
- How does the efficiency and reliability of natural convection cooling compare to other cooling methods?
In a high temperature environment, the liquid cooling system will control the battery temperature in a suitable range, and the temperature difference between the cells will not be more than 1-2 degrees, the normal air-cooled system temperature difference will reach more than 5 degrees, so the operating temperature is controlled within a reasonable range.
The efficiency will reach 98%.
7. Installation and Logistics:
- Could you outline the logistical requirements for transporting and installing this system in a remote area?
- Is specialized equipment or training necessary for the initial setup?
At present, the mode of transport is by sea, the goods will be delivered to the port near the project, and then take the trailer to the installation site, the installation of the system needs to have an electrician's licence to install the technician, the installation and commissioning has been completed in the factory, and then wiring can be transported to the destination point.
The system is installed in the factory when the internal installation has been completed, when the customer receives the goods in the case of wiring can be used.
Because of the simplicity of installation, we will provide customers with wiring diagrams and factory test installation videos for initial installation, so as to facilitate customer installation and wiring.
We can provide online guidance, if the customer is still on the installation of questions, if the project capacity is large, we will arrange for a technician to the project site installation, the list of costs according to the country, the size of the project, as well as the number of days to decide!
8. Cost-Effectiveness and Lifecycle:
- What is the estimated lifespan of the batteries and the overall system?
- Are there any significant recurring costs or maintenance expenses to be considered?
Liquid-cooled battery system has a life span of 15-20 years.
1. In the warranty period, all the cost of parts, maintenance costs will be provided by the supplier, to provide on-site installation guidance and maintenance training.
2. Maintenance and training manual information location installation, the cost list should be in accordance with the country, the size of the project, as well as the number of days to determine the.
9. Communication and Monitoring:
- What remote monitoring and control options are available, and how reliable are they in remote settings?
- How does the system handle software updates and technical support from a distance?
We can monitor our energy storage systems remotely from our computers, as well as monitor power generation, consumption and other data indicators on our mobile apps.
We will handle the software updates supports from remote.
