Sigenergy 25.0kW SigenStor Three Phase Controller
A smart, flexible controller designed to manage your three-phase solar and battery system with ease. It helps you maximise energy efficiency, supports high loads, and keeps your home or business powered up reliably — all in one sleek unit.

Sigenergy 25.0kW SigenStor Three Phase Controller

The Sigenergy 25.0 kW SigenStor Three Phase Controller is a fully integrated, AI-optimized hybrid inverter and energy management system in an IP66-rated enclosure. It combines solar conversion, bidirectional battery power conversion, EV DC-charger interface, battery-pack communication, and an embedded Energy Management System (EMS) into a single unit. With a continuous three-phase output of 25 kW, up to four independent MPPT trackers, multi-source black-start capability, and DC ground-fault protection, it delivers seamless on-grid/off-grid operation and rapid backup switching for residential and light-commercial solar-plus-storage installations

Key Features

• 5-in-1 All-In-One Design
  Integrates solar inverter, EV DC-charger, battery PCS, battery-pack interface, and EMS into one streamlined system

• 25 kW Continuous Three-Phase Output
  Supplies up to 25 000 W of AC power (nominal) with short-term peak capability for high-demand loads

• Up to Four MPPT Trackers
  Four independent maximum power point trackers optimize energy harvest under shading or uneven array layouts

• Multi-Source Black-Start
  Coordinates battery storage, PV arrays, and backup generators to re-energize critical loads without external grid power

• DC Ground-Fault Protection
  Built-in detection and isolation meet safety standards without external leak-protection devices

• IP66-Rated Durability
  Fully dust-tight and protected against powerful water jets, suitable for indoor or outdoor installation

• AI-Optimized EMS
  Embedded machine-learning algorithms enable intelligent peak shaving, time-of-use optimization, and system diagnostics via the mySigen app

• Vehicle-to-Home & Vehicle-to-Grid Ready
  EV integration allows the controller to work with bi-directional EV chargers for V2H/V2G applications, expanding virtual grid capacity
