Thermal bucket

Thermal bucket

The no-welding process uses the latest interlocking technology, which involves physically folding stainless steel materials and interlocking them, with silicone added at the interlocking points to prevent leakage. The inlet and outlet, exhaust port, and air energy interface all utilize the interlocking process, achieving a completely no-weld design. During the production of the insulation barrel, product quality is primarily controlled by CNC machinery, resulting in low dependence on employee skill levels, with a defect rate below 0.1%. Production costs are effectively controlled.

Solar energy dedicated lithium battery

Solar energy dedicated lithium battery

Solar special lithium battery: Power is 40AH/12V. The capacity should meet the power consumption requirements for 10-12 hours and comply with the YD/T799 standards. When using other batteries, they must meet the corresponding national and industry standards, and harmful gas emissions must be prevented. The battery must be installed inside a chassis, which should consider ventilation, waterproofing, and anti-theft features. The charge and discharge cycle count should exceed 2500 times, and it should operate reliably over a long period at temperatures between -10 to 40°C. It should provide lighting for 5-7 consecutive rainy days, with the capacity meeting the requirements for lighting duration and continuous rainy days. The lifespan of the lithium battery should reach over 10 years.

The charging principle of a charging pile

The charging principle of a charging pile

The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with charging plugs for charging electric vehicles. Charging piles generally provide two charging methods: regular charging and fast charging. Users can swipe a specific charging card on the human-machine interaction interface provided by the charging pile to perform corresponding charging operations and print cost data. The display screen of the charging pile can show data such as charging amount, cost, and charging time.

Precautions for Cleaning Photovoltaic Modules

Precautions for Cleaning Photovoltaic Modules

Safety Inspection: Before cleaning the components, check the monitoring records for any abnormal power output entries, analyze whether it may be caused by leakage, and inspect the connection wires and related components for any damage or adhesion. Additionally, use a voltage tester to test the aluminum frame, brackets, and tempered glass surface of the components to eliminate the risk of electric leakage and ensure personal safety.

The role of a solar photovoltaic (PV) controller.

Protecting the battery: Prevent overcharging and over-discharging of the battery to extend its lifespan. When the charging voltage exceeds the protection voltage, the controller will automatically stop charging the battery to prevent overcharging; when the battery voltage falls below the protection voltage, the controller will automatically shut off the output to prevent over-discharging.

The main functions of solar photovoltaic inverters include:

The main function of a solar photovoltaic inverter is to convert the direct current (DC) generated by photovoltaic modules into alternating current (AC) for household or commercial use, allowing the electricity to be smoothly connected to the grid and providing a stable power supply for various electrical devices. The photovoltaic inverter plays a crucial role in solar power generation systems.

BMS (Battery Management System Controller): BMS is the core component for protection and management in the power battery system. It is mainly responsible for monitoring the state of the battery, preventing overcharging and over-discharging, and extending the battery's lifespan. BMS controls the charging and discharging of the power battery pack through contactors and reports the substrate parameters and fault information of the power battery system to the Vehicle Control Unit (VCU).
