SolarEdge Launches Nexis Solar Storage in Austria, Switzerland

SolarEdge has announced that its next-generation SolarEdge Nexis residential solar and storage system is now available for order in Austria and Switzerland. Following a highly successful launch in Germany, where the company rapidly secured thousands of orders and completed over 1,300 installations, the new system introduces an entirely redesigned architecture from the inverter to the battery. By combining a three-phase inverter with a modular, stackable battery system and full-home backup capabilities, the Nexis platform is designed to help homeowners seamlessly transition toward energy self-consumption while drastically reducing installation complexity.

Advanced Silicon Carbide Inverter Architecture
At the core of the Nexis system is a compact, three-phase inverter capable of delivering up to 20kW of power. Weighing just 30.6 kg, the unit utilizes advanced Silicon Carbide (SiC) semiconductor technology to maximize efficiency, power density, and thermal performance. Unlike traditional systems that lose significant efficiency at low power levels, the SiC-equipped Nexis inverter operates with up to 20% higher efficiency in low-power conditions compared to leading competitors. Furthermore, SolarEdge’s MultiRange concept consolidates all power classes into a single part number, simplifying inventory management and enabling installers to complete commissioning in under 30 minutes via an integrated software interface.




Modular Storage and Enhanced Safety
The SolarEdge Nexis Battery introduces a modular, "Lego-like" Simple-Click™ design that eliminates the need for complex wiring between modules. Using 5 kWh lithium iron phosphate (LFP) battery blocks, homeowners can scale their storage capacity up to 20 kWh per stack, with a maximum of 80 kWh across four stacks per inverter. A built-in Battery Optimizer independently isolates, monitors, and manages each block to balance the state of charge and increase overall system efficiency. The system also incorporates ThermoShield™ safety technology, providing multi-layered protection that meets UL 9540A standards by containing potential thermal events to a single cell.




Additional Context
This section outlines technological and market dynamics not included in the original release.

The residential energy storage market in Europe is rapidly shifting from feed-in tariff incentive models to self-consumption models, driven by high retail electricity prices and the need to support larger household energy loads. By transitioning to LFP battery chemistry—which is increasingly becoming the industry standard due to its longer cycle life and thermal stability—SolarEdge addresses consumer demands for longevity and safety. The Nexis system's DC-coupled architecture minimizes conversion losses, positioning it as a highly competitive solution against AC-coupled alternatives like the Tesla Powerwall. Furthermore, the system's enhanced locked rotor amp (LRA) capabilities allow it to supply the quick bursts of energy required to start heavy motor loads, such as air conditioning units, during grid outages.
