Off-Grid Photovoltaic DC Grid System

Product Introduction

This product is a hybrid energy storage system combining lithium iron phosphate batteries and supercapacitors. By integrating energy-oriented lithium iron phosphate storage with power-oriented supercapacitor technology, the system achieves coordinated scheduling through an intelligent EMS (Energy Management System).

It can be directly connected to existing power supply systems without modifying the original circuits. By combining instant power buffering capability with long-duration energy storage, the system provides reliable, efficient, and green energy storage solutions for various application scenarios. It also supports both AC and DC coupling connection methods.

Outstanding Supercapacitor Performance

Supercapacitors feature an extremely long charge and discharge cycle life, with more than 1 million cycles, far exceeding traditional energy storage batteries.

They can continuously and reliably handle frequent high-power charging and discharging demands in high-impact load scenarios, significantly reducing equipment degradation and replacement costs.

Meanwhile, supercapacitors can efficiently absorb instantaneous power fluctuations and provide power support, reducing the required capacity and quantity of lithium iron phosphate batteries. This helps lower both initial investment costs and long-term operation and maintenance expenses.

Stable and Reliable Power Supply

With millisecond-level response capability, supercapacitors can quickly buffer sudden power fluctuations, effectively preventing voltage fluctuations and current surges.

This helps avoid equipment shutdowns and ensures continuous and stable power supply.

Flexible Expansion and Easy Integration

The system can be directly connected in parallel with existing power supply systems without modifying the original circuits, resulting in shorter upgrade cycles and lower implementation costs.

It also supports flexible expansion through multiple units, making it suitable for both existing system upgrades and new projects with strong adaptability.

Safe and Compliant

The system adopts an explosion-proof design with multiple safety protection mechanisms, making it suitable for special operating environments such as flammable and explosive conditions.

It fully complies with industry safety and environmental protection standards, ensuring safe and reliable operation.

Energy Saving and Consumption Reduction

The system can efficiently recover unused energy such as potential energy and braking energy in application scenarios.

It helps smooth power fluctuations, reduce fuel consumption and carbon emissions, support green operations, and lower overall operating costs.

Drilling Platform Application

During the drilling platform operation cycle, when electricity demand is relatively low in the early stage, the utilization of lithium battery energy storage units can be reduced to lower operating costs.

As power demand increases in later stages, the system can flexibly adjust lithium battery storage capacity according to actual load requirements.

While solving power supply challenges in drilling platform applications, the system significantly reduces energy storage investment costs and improves overall reliability through the long lifespan and enhanced safety of supercapacitors.
