It All Just Clicks Into Place
SolarEdge Simple Click™ architecture is designed to make battery installation fast, secure, and straightforward. Simply stack each Battery Block, click it into place, and secure the completed stack to the wall.
- No inter-block wiring required
- Click-and-lock Battery Blocks for faster assembly
- Secure the completed stack to the wall in minutes
Battery Optimizer: Keep Performance at Its Best
An integrated Battery Optimizer independently manages each Battery Block to help improve system efficiency, thermal performance, and battery longevity.
By activating Battery Blocks as needed, the system helps preserve available battery capacity while maintaining reliable operation.
- Improved thermal management
- Always-On design allows continued operation if one Battery Block becomes unavailable
- Supports mixing existing and new Battery Blocks with automatic recalibration
Optimized for Dynamic Tariffs
Intelligent battery operating modes determine when to use solar energy, store it for later, or draw power from the grid—helping maximize savings, backup duration, and energy independence.
Reliable Power in Extreme Conditions
Built for demanding environments, the SolarEdge Nexis Battery provides robust protection against weather, temperature extremes, and water exposure.
Its dust-tight and watertight construction is complemented by advanced heating films designed to support reliable performance in cold conditions.
- -4°F to 131°F operating range - Reliable performance through freezing winters and hot summers
- Quiet operation - Less than 40 dBA nominal and less than 50 dBA under extreme conditions
- Flood resistant - Designed to withstand up to 18 inches of standing water for up to 72 hours
Multi-Layer Battery Protection
Not all battery systems provide the same level of protection. SolarEdge Nexis incorporates multiple layers of fire, electrical, and thermal protection designed to help keep the system operating safely and reliably.
Cell Chemistry
Premium lithium iron phosphate (LFP) cells provide enhanced thermal stability, safety, and cycle life compared with many other lithium-ion battery chemistries.
Cell-Level Protection
SolarEdge ThermoShield™ technology is designed to protect individual LFP cells and help prevent cell-to-cell thermal runaway propagation in accordance with UL 9540A testing requirements.
Battery Block-Level Protection
An integrated array of temperature sensors continuously monitors each Battery Block and helps mitigate overheating. The Always-On architecture allows the battery system to continue operating even if an individual Battery Block becomes unavailable.
Battery Stack-Level Protection
The complete Battery Stack is designed to resist thermal runaway propagation while providing durable protection against environmental conditions. Its dust-tight and watertight construction supports reliable operation from -4°F to 131°F, while integrated heating technology helps maintain performance in cold environments.
