Three Phase Hybrid Inverter On & Off-Grid IP66 G98 / G99 / G100 Certified 10-Year Warranty

The three-phase SigenStor Energy Controller delivers the same 5-in-One platform as the single-phase range but across a balanced three-phase AC supply, making it suitable for three-phase residential properties and light commercial installations. Available in five power ratings from 10.0 kW to 25.0 kW, the TP series supports up to six SigenStor battery modules per stack, the optional EV DC Charging Module for V2X/V2G, and integration with Sigenergy's HomeMax or HomePro gateway for whole-home or partial backup. All models carry G98, G99, and G100 grid compliance certificates for UK DNO notifications and export control.

  • Three-phase output — suitable for 3-phase metered properties and commercial premises
  • EMS inside — balances load across all three phases intelligently
  • Multi-source black start — solar, battery or generator sources
  • DC ground-fault protection
  • DC/AC ratio up to 2:1 — supports generously oversized PV arrays
  • IP66 rated — outdoor wall or ground mount
  • Up to 6 battery modules per stack (5 when EV DC Charging Module is installed)
  • G98 / G99 / G100 certificates — covers export limitation requirement; available on request by email
  • Compatible with SigenStor HomeMax TP and HomePro TP gateways for backup
  • 10-year product warranty
ℹ️ All five TP models share the same physical platform (5.0–25.0 kW range) with output power field-configurable. For installations requiring whole-home backup, the Sigenergy HomeMax TP or HomePro TP gateway is required in addition to the Energy Controller.
