Series: TESVOLT TAYTAN Series

TAYTAN 400/426

Three-phase integrated bess inverter all-in-one system with 426 kWh LFP battery

Partially verified

Best for

  • + Commercial & industrial installations
  • + Three-phase installations
  • + Large industrial & utility-scale (200+ kWp)
  • + Projects requiring long warranty coverage
  • + LFP battery applications - verify cycle life from datasheet

Not ideal for

  • ! Typical single-family residential - consider residential product line
  • ! Single-phase installations (unless manufacturer confirms support)
  • ! Small commercial applications (< 30 kWp) - consider smaller product
  • ! Backup/battery-backup projects (no EPS functionality)
  • ! Projects requiring future expansion - AIO unit does not support parallel expansion
