Fire Protection System
The overall energy storage cabinet can be divided into two separate protection areas.
The concept of "multi-level protection" is mainly to provide fire protection for the two separate protection areas and make the entire system act in association, which can truly put out the fire quickly.
And prevent it from re-igniting, ensuring the safety of the energy storage station.
The two separate protection zones:
- PACK level protection: The battery core is used as the source of fire, and the battery box is used as the protection unit.
- Cluster level protection: The battery box is used as the fire source and the battery cluster is used as the protection unit
Pack Level Protection
The hot aerosol fire extinguishing device is a new type of fire extinguishing device suitable for relatively enclosed spaces such as engine compartments and battery boxes.
When a fire occurs, if the temperature inside the enclosure reaches around 180°C or an open flame appears,
the heat-sensitive wire detects the fire immediately and activates the fire extinguishing device inside the enclosure, simultaneously outputting a feedback signal.

The benefits of using photovoltaic energy storage systems for farmland irrigation are many and can have a significant impact on agricultural production.
Some key benefits include:
1. Cost savings: By harnessing solar energy and storing excess electricity, farmers can reduce their reliance on the grid or diesel generators, thereby lowering energy costs over time.
2. Energy independence: The system provides a reliable, sustainable source of power, reducing dependence on external energy suppliers and increasing the farm’s energy self-sufficiency.
3. Environmental sustainability: Solar energy is a clean, renewable energy that helps reduce greenhouse gas emissions and environmental impact compared to traditional energy sources.
4. Reliable water supply: Even when there is insufficient sunshine or at night, the system can ensure continuous power supply for irrigation, helping to maintain continuous water supply for crops.
5. Long-term investment: Installing a photovoltaic energy storage system can be a long-term investment, providing a reliable and sustainable source of energy for years to come, with the potential for good return on investment.
6. Government incentives: In many areas, there are government incentives, tax credits or rebates for installing renewable energy systems, which can further offset the initial investment cost.
Overall, photovoltaic energy storage systems for farm irrigation offer a range of advantages, including cost savings, energy independence, environmental sustainability and long-term reliability, making them an attractive option for modern agricultural operations.
