Sunsynk 20kW–25kW Three-Phase HV Hybrid Inverters
Product overview
Sunsynk 20kW–25kW Three-Phase HV Hybrid Inverters
The Sunsynk 20kW Inverter (SUNSYNK-20KSG01HP3-EU-AM2) and Sunsynk 25kW Inverter (SUNSYNK-25KSG01HP3-EU-AM2) are high-efficiency, three-phase hybrid storage solutions for large-scale residential, commercial and industrial applications. Ideal for marine (vessel power management), power shedding (home, office and factory), UPS systems, building sites, telecommunications, and remote locations with solar or wind generation, these inverters seamlessly manage energy from multiple sources. This includes solar, grid power, generators and high-voltage batteries, while providing reliable, uninterrupted power.
A standout feature of the 20kW Three-Phase Inverter and 25kW Three-Phase Inverter is intelligent phase balancing. Even with uneven loads (e.g., 20% / 20% / 60% across phases), these inverters maintain perfect phase rotation for optimal performance. No other inverters in this class offer such precise load management.

Key Features & Benefits
Individual MPPT per battery string and solar input ensures maximum efficiency, even with uneven load distribution across phases- Advanced three-phase load balancing maintains perfect phase rotation under uneven load conditions
- Clear, interactive LCD display with real-time power flow visualisation and user-configurable settings
- RS485 Wi-Fi interface enables remote monitoring and control
- Smart settable 3-stage MPPT charging optimises solar generation and battery performance
- Supports grid, generator, and wind turbine inputs. DC and AC coupling allows retrofitting into existing solar systems.
- Maximum charging/discharging current of 250A for high power capability
- Parallel capability supports up to 4 inverters for larger energy systems
- 230V/400V three-phase pure sine-wave output powers both single-phase and three-phase loads
- Fully programmable controller: Adjustable supply priority (battery or grid), multiple operating modes (on-grid/off-grid/UPS), and configurable charging parameters
- Overload, over-temperature, and short-circuit protection with smart battery protection design and isolation transformer
- Self-consumption optimisation with grid feed-in capability and limiting function to prevent excess export
- Auxiliary load output, auto restart on AC recovery, and six configurable time periods for battery charging/discharging
- Ideal for marine, power shedding, UPS systems, remote/off-grid installations, building sites, and telecommunications
