Nexis Battery
Nexis Battery is a modular SolarEdge energy storage with LiFePO4 cells, designed for single- and three-phase residential systems. A design that includes 1–4 battery modules in one stack allows usable energy to be tailored to household needs. An independent power module in each battery module optimizes backup power operation and efficiency.
Key advantages of Nexis Battery
- Scalable usable energy: 4.65–18.6 kWh per stack, depending on the number of battery modules; each stack requires a Battery Link.
- Continuous charge and discharge power: 3.5–13 kW in single-phase systems and 3.5–14 kW in three-phase systems, depending on configuration. Power may vary with temperature.
- ThermoShield™ technology: designed to prevent uncontrolled temperature propagation between cells.
- Simple-Click™ connections: self-locking mechanical and electrical connections between battery modules and the Battery Link simplify safe installation.
- Indoor or outdoor installation: IP65 enclosure and operating temperature range from −20 to +55°C. When installed in direct sunlight the maximum ambient temperature is +45°C; wall mounting requires a separately sold bracket.
- 10-year warranty: specific terms are defined by the manufacturer’s limited warranty.
Who is this a good choice for?
Nexis Battery is intended for households using a compatible SolarEdge Nexis inverter in single- or three-phase installations. The modular design suits users who select storage capacity to match their needs, and the independent power modules are important for those using backup power. The option for indoor or outdoor installation allows selecting the installation location according to available space and the manufacturer’s requirements.

Charging and discharging power depends on temperature. Efficiency was measured at a cell temperature of 35°C with fans turned off. Currently up to 12 blocks in 3 stacks per three-phase inverter are supported; support for a fourth stack requires a future software update. When in direct sunlight the maximum ambient temperature is 45°C. Wall mounting requires an additional bracket. The expected lifetime refers to one cycle per day, charging at 0.25 C and discharging at 0.1 C under German climatic conditions.
