STORAGE SYSTEM FOR STAND-ALONE OFF-GRID SOLUTIONS | Onis Visa BESS Off-Grid solutions
The Onis Visa Energy Storage is a modular storage system based on high density LLP (Low Lithium and Polarization) batteries. It is ideal for off-grid applications, since it guarantees operational continuity and optimization of the energy costs. With the increasing demand for efficient and sustainable energy solutions, BESS systems are becoming an essential component for industries, manufacturing factories and critical infrastructures.
What is a Battery Energy Storage System (BESS)?
The Battery Energy Storage Systems (BESS) are advanced technological devices designed to store power energy and release it when it is needed. They represent a flexible and reliable solution to manage the energy supply intelligently. Because of their ability to store energy from different sources, such as electricity grid, generating sets, photovoltaic systems or renewable generation plants, BESS can balance energy demand and supply, reducing operating costs and improving sustainability.
The benefits of the Onis Visa BESS system
- Modularity: it is adaptable to any kind of installation and configuration.
- Sustainability: Zero emissions and compatibility with photovoltaic, hydroelectric and wind power plants.
- Remote monitoring: Thanks to our dedicated software it is possible the monitoring and the management of the machine parameters.
- Easy maintenance: User-friendly system with scheduled maintenance options to minimize downtime.

Possible applications of the BESS systems
- Load Leveling: BESS systems allow energy to be stored during low-cost periods and used when power rates get higher, contributing to the reduction of operating costs;
- Peak Shaving: During peaks in energy demand, the Onis Visa BESS System manages energy predictively so as not to overload the mains, reducing costs and preventing power outages;
- Power Backup: In the event of power supply interruptions, BESSs ensure the operational continuity of critical infrastructures such as hospitals, data centers, and industrial plants;
- Integration with renewable sources: BESS systems can be integrated with renewable energy sources such as photovoltaic, wind or hydroelectric, storing the energy produced to be used in periods of low production or high demand;
- Energy optimization: Through intelligent energy management, BESS improve the overall efficiency of the energy system, contributing to a significant reduction in the carbon footprint.
