Energy storage system – SOLAREDGE – CSS-OU-01-06-CA-107-01

CSS-OD 107

The CSS-OD 107 from SolarEdge is an energy storage cabinet with lithium iron phosphate (LFP) cells, designed for commercial and industrial installations. It offers 107.52 kWh of total capacity and 102.14 kWh of usable capacity. Integration with SolarEdge ONE enables self-consumption optimization, peak shaving, and energy management that takes tariffs and import and export limits into account.

Key benefits of CSS-OD 107

• Usable capacity 102.14 kWh — six LFP modules and the ability to scale the system up to 2.1 MWh.
• Indoor or outdoor installation — a cabinet with an IP54 protection rating, C4 corrosion protection and an integrated heating, ventilation and air conditioning system.
• Multi-level protection — protection at cell, module, cluster and cabinet levels, integrated fire detection and suppression, and CO, smoke and flood sensors.
• Preparation for quick start-up — factory assembly and testing, and configuration using the SolarEdge Go app. System operation requires a SolarEdge ONE controller.
• Provision for backup power function — requires a firmware update, expected later in 2026 according to the datasheet; the function is limited to one energy storage inverter per installation.
• 10-year system warranty — the performance warranty covers 8000 cycles or 10 years down to 70% battery state of health (SoH), subject to the terms and exclusions of the manufacturer’s limited warranty.

Who is this a good choice for?

CSS-OD 107 is designed for businesses and industrial facilities seeking to increase energy self-consumption, reduce peak demand or optimize the use of electricity tariffs. Expandability up to 2.1 MWh meets the needs of users planning to increase storage capacity, while indoor or outdoor installation allows the cabinet location to be tailored to the installation.
