What it is

The Sunpura U8000 AC is the largest single unit in the range: 8 kWh of storage in one integrated, plug-and-play enclosure. Its differentiator is the battery chemistry, SolidCore semi-solid cells, an EV-grade technology chosen for higher safety, longer life and better tolerance of the environment. It is AC-coupled, so it adds to a home that already has solar without rewiring the array.

High capacity, one unit

Where the stackable models build up in modules, the U8000 AC delivers 8 kWh in a single integrated cabinet with 3,680 W of continuous output and a 5,520 VA surge. It suits a home that wants substantial overnight storage and strong backup, added onto existing solar.

Why the U-series is different

  • SolidCore semi-solid chemistry: EV-grade cells, engineered for safety and longevity.
  • 8 kWh in one integrated unit, plug-and-play.
  • AC-coupled retrofit: works alongside an existing solar/inverter system.
  • Dual-band Wi-Fi and Bluetooth, managed in the Sunpura HOME app.
