Advantage 2
Ultra-Fast Grid-to-Backup Switching
<10ms Ultra-Fast Grid-to-Backup Switching

Our commercial and industrial energy storage system switches to off-grid mode within 10ms during grid fluctuations or outages, ensuring continuous power for critical loads and operations.

Excellent Weather Resistance

Our products are capable of being used in temperatures ranging from -20°C to 50°C. Any extreme harsh environment of extreme cold or heat will not affect the normal operation of it. This product utilises air-cooling technology and has a built-in over-temperature protection system, which makes it safer and more reliable.

Weather Resistance Performance
Highly Integrated Design
Highly Integrated All-in-one Design

Our all-in-one design combines battery, PCS, and EMS for seamless compatibility, faster installation, easier maintenance, enhanced safety, and flexible expansion—optimizing energy management and reducing costs.

Applications
This all-in-one 215kWh battery energy storage system can be used with solar panels and diesel generators to support microgrid applications. It offers multiple configurations to adapt to different scenarios and enables seamless switching. Below are the options we can offer you.
Application-1
Operating Mode: Solar energy is prioritized for storage in batteries. Excess power supplies the load. When solar energy is insufficient, stored energy powers the load.
Application Scenarios: Addresses small-scale power supply needs in remote areas.
Application Value: Addressing electricity needs in remote areas and enhancing power usage efficiency.
Application-2
Operating Mode: Photovoltaic energy is prioritized for storage in batteries, with surplus power supplying loads. When PV output is insufficient, stored energy first powers loads, and if insufficient, a diesel generator then supplies power to loads.
Application Scenarios: Addresses medium-scale power supply needs in remote areas such as islands, large villages, and factories in areas with weak electrical infrastructure.
Application Value: Solves the challenges of constructing grid-connected power facilities and high electrification costs in areas without electricity or with weak electrical infrastructure, providing continuous power supply.
Application-3
Operating Mode: Energy storage enables rapid response to load power fluctuations, ensuring the diesel engine consistently operates at optimal efficiency.
Application Scenarios: Addresses power supply needs in areas with weak electrical infrastructure, such as construction sites, oil drilling rigs, and large villages.
Application Value: Maximizes diesel engine efficiency, reduces engine wear, lowers fuel costs, and rapidly accelerates return on investment.
