The bridge between the grid and energy storage

The SunLink hybrid inverter is the brain of your home energy system. It does more than convert solar into usable power - it intelligently manages energy flow between grid, battery and household loads. While the grid is healthy, solar comes first; during outages it switches seamlessly to battery backup. Our inverters support multiple battery types and offer remote monitoring, making energy management simple and intuitive.

Seamless Switching

Switches to backup power within milliseconds when the grid goes down, keeping critical loads online

Smart Dispatch

Automatically optimizes energy flow between solar, battery and grid to lower your electricity bill.

Strong Compatibility

Compatible with mainstream lithium and lead-acid batteries for flexible system design.

Remote Monitoring

Track real-time status from a mobile app and stay on top of your energy usage anywhere, anytime.

High-Efficiency Conversion

Advanced MPPT technology maximizes solar harvesting efficiency.
