SolarEdge Nexis Battery: An Integrated Solar-Plus-Storage Solution
SolarEdge Nexis Battery is a modular battery system based on lithium iron phosphate (LFP) technology that works in tandem with the SolarEdge Nexis Inverter. The battery stores extra solar energy that can later be used when there is less solar power production, high electricity prices, or no power from the grid.
It is designed for new solar system installations and retrofit projects. Its expandable battery storage architecture gives you the ability to choose the battery capacity according to your energy needs.

SolarEdge Nexis Battery Incentives and Financing
Battery storage incentives depend on your state, utility, property type, and program. Based on your state, you might be eligible to apply for state or utility company battery storage rebates or demand-response programs, among others. For commercial projects, applicable financing arrangements and tax provisions may also be worth evaluating with a qualified tax professional. Eligibility depends on current law, ownership structure, project specifications, and other requirements. Residential customers may also explore third-party-owned solar and storage arrangements where available. Solar SME can help you identify programs worth investigating, but incentive availability and savings should be confirmed before you commit to an installation.

Frequently Asked Questions
The SolarEdge Nexis Battery uses modular 5 kWh battery blocks that can be combined into stacks of up to 20 kWh nominal capacity. Up to 4 stacks can connect to one inverter, for up to 80 kWh nominal. Support for 3 stacks begins in July 2026, with the 4th stack expected in Q1 2027. This lets storage capacity scale with your energy consumption and backup requirements.
SolarEdge Nexis supports AC- or DC-coupled configurations, depending on the system design. However, compatibility with an existing solar installation depends on the inverter, electrical configuration, and applicable product requirements. A professional assessment can help determine whether a retrofit is suitable.
SolarEdge Nexis offers configurations with different storage capacities and power outputs, but suitability for commercial projects depends on the specific model, approved application, electrical requirements, and required backup capacity. Solar SME can help assess your project's needs and identify compatible energy storage options.
