Specifications
Product Description
The Solax ULTRA 25000W X3-ULT-25K Three-phase Hybrid Solar Inverter is designed for advanced commercial and residential installations that require high power, storage, and service continuity. Its hybrid electronics precisely manage energy from the panels, the grid, and the high-voltage battery, with EPS switching <10 ms to keep critical loads running during an outage. With 3 high-current MPP trackers, IP66 enclosure, and professional control functions, it maximizes self-consumption and reduces annual energy costs.
Main Features
- AC nominal power 25 kW three-phase; apparent output 110 % (≈27.5 kVA).
- 3 independent MPPT (2+2+2 strings) with 36 A per MPPT and Isc 45 A; MPPT range 160–950 V; max Vdc 1000 V.
- High-voltage battery 120–800 V with 60 A bidirectional charge/discharge (30 A ×2).
- Backup <10 ms with 200 % peak for 10 s for demanding startups.
- Photovoltaic oversizing 200 % and export management to achieve zero feed-in.
- Max efficiency 98.0 %; European 97.7 %; night consumption <5 W.
Advantages or Benefits
- Operational continuity: ultra-fast EPS for IT, refrigeration, lighting, and variable speed drives.
- Savings with intelligence: time-of-use (ToU) scheduling, export control, and smart load to prioritize consumption.
- More usable kWh: 3 high-current MPPT and 200 % DC oversizing to maximize mornings and evenings.
- Industrial safety: IP66, SPD Type II on DC/AC, and optional AFCI.
- Scalability: parallel connection of up to 10 units on/off-grid and ready for VPP/microgrid.
Purpose or Applications
Designed for SMEs, retail, workshops, restaurants, and three-phase homes with high consumption that require 25 kW with HV battery, configurable feed-in limit, and fast backup. Perfect for integrating heat pump, EV charger, and critical load management.
