Project: 5kWh industrial-frequency off-grid Energy Storage System (3kW / 5kWh, Pure Sine Wave output)
Application: Off-grid power supply for remote islands/villages + emergency backup (for lighting, small appliances, medical precision equipment)
Location: Remote islands, Sabah, Malaysia, Southeast Asia

Remote islands in Southeast Asia lack public grids. Diesel generation is costly, polluting, and may damage sensitive equipment. Logistics, installation, and after-sales services are also challenging. This solution integrates industrial-frequency storage with small-scale PV, ensuring clean power supply with pure sine wave output to protect sensitive equipment, fully replacing diesel generators. On-site training is provided for local operation and maintenance.

The 5kWh system, combined with PV, enables daytime charging and nighttime supply. With IP65 protection, it withstands salt spray and high temperatures. A localized emergency response system ensures timely inspection, spare parts supply, and fault repair, providing reliable power support even in remote areas.
