Island energy storage solutions

Addressing island power challenges, GSL provides a complete off-grid solution. On Saipan Island, power is primarily generated by fuel-powered generators, resulting in an unstable supply and extremely high costs. In this project, the client selected GSL ENERGY's energy storage system, combining photovoltaic power generation with lithium-ion battery storage to effectively address the following issues:

Stable Power Supply: The system can operate completely off-grid, enabling a 24/7 off-grid self-sufficient power supply

UL Certification Assurance: Batteries comply with North American market safety standards for safe use

Flexible Configuration: A combination of 3 x 10kWh and 2 x 5kWh batteries to accommodate varying load requirements across different power zones

Plug-and-play: Highly compatible with mainstream inverters, ensuring easy installation.

Resistant to island climates: Features corrosion resistance, moisture resistance, and high-temperature resistance, making it particularly suitable for tropical marine environments.

Wider applications: Serving users in remote regions worldwide.

GSL ENERGY is committed to providing customized off-grid energy storage system solutions for remote and off-grid regions globally. Typical applications include:

Island nations, such as Fiji, the Maldives, and Mauritius

Highland regions, such as South American mountainous areas, African inland regions, and Southeast Asian islands

Off-grid villages and remote communities: providing independent power systems for schools, hospitals, farms, and more

Key features of GSL ENERGY's off-grid systems:

Supports flexible configurations from 5kWh to 5MWh

Modular design for easy scalability and maintenance

Intelligent Battery Management System (BMS) ensures system safety and efficiency

Global certifications: UL, CE, UN38.3, MSDS, etc.

Factory direct supply, supporting OEM/ODM/OBM customization

GSL ENERGY is not only a manufacturer of energy storage products but also a pioneer in global off-grid power solutions. We are committed to bringing the power of light and energy to every remote corner of the world.
