3 XOLTA BATTERY ENERGY STORAGE SYSTEM:
3.1 Main features
The XOLTA Compact BESS system can be easily integrated into any house or building. It is perfect for
retrofitting to existing solar panel installations as well as for brand new installations. The main features of
the XOLTA Compact BESS are:
• PLUG AND PLAY: Simple installation and commissioning. All the battery requires is electrical grid connection,
internet access and electrical meter connections.
• SINGLE and 3-PHASE: The system can be used for both single and 3 phase operation.
• ALL IN ONE: All system components are integrated into a single cabinet. This includes the battery cells,
the power conditioning system (PCS), the thermal management system (TMS), the battery management
system (BMS) and the energy management system.
• INDOOR and OUTDOOR OPERATION CAPABILITY: The mechanical casing of the system was designed to
be effective up to enclosure protection rating IP55 (dust and water jet proof).
• MODULARITY: The storage system power and energy can be expanded and tailored to specific needs. In total,
up to 3 XOLTA Compact batteries can be connected and operated in parallel giving up to 10.8kW and 30kWh.
• MULTIPURPOSE: The battery is designed for various applications: solar self-consumption, time shifting, etc.
• XOLTA CLOUD CONNECTION: The battery is integrated with the XOLTA Cloud. It allows for system monitoring,
control, data acquisition, and data storage.
• SAFETY: The battery is designed to offer exceptionally high operational safety. For example, the system is
fitted with state of the art and safe battery systems, multi-layer, and redundant protection systems, as well
as a battery management system (BMS) from Lithium Balance which ensures maximal system safety
under various operating conditions.
• LOW TOTAL COST OF OWNERSHIP: This is achieved by very high system round-trip efficiency, ultra-low
standby losses, high cycle lifetime, minimal operational and maintenance (O&M) cost and intelligent energy
management.
• SITE CONTROLLER: This works as an energy management system (EMS) which manages the entire XOLTA
Compact BESS. It provides charge/discharge power management, monitoring to ensure safe battery
operation, communication with all system peripherals (e.g. the battery inverter), data acquisition,
communication with the XOLTA Cloud, system diagnostics and error handling.
• THERMAL MANAGEMENT: Simple, efficient and silent thermal management system.
