Specifications
Product Description
The Solax ULTRA 15000W X3-ULT-15K Three-phase Hybrid Solar Inverter brings storage to advanced commercial and residential installations that require service continuity and full control. With an IP66 enclosure, 2 high-current MPPTs, and EPS <10 ms backup, it intelligently manages energy between panels, HV battery, and grid to maximize self-consumption and ensure critical loads in case of outage.
Main Features
- 15 kW three-phase nominal AC power with apparent output up to 16.5 kVA (110%).
- 2 independent MPPTs (2/2 strings) with 36 A per MPPT and Isc 45 A; MPPT range 160–950 V and max Vdc 1000 V.
- High voltage battery 120–800 V; charge/discharge 60 A (30 A ×2) for fast response.
- Switching to EPS <10 ms with nominal power of 15 kVA and 200% peak for 10 s.
- PV oversizing up to 200% and AC output 110% to take advantage of peak irradiation.
- Max efficiency 98.0%; European 97.7%; night consumption <5 W.
Advantages or Benefits
- Business continuity: almost instantaneous backup for IT, refrigeration, lighting, and sensitive equipment.
- Energy savings: tariff-based scheduling (ToU), export control, and load management (heat pump, EV charger).
- Higher annual production: 200% oversizing and built-in shadow tracking.
- Professional electrical safety: IP66 and SPD Type II on DC/AC; optional AFCI.
- Scalability: up to 10 units in parallel on-grid and off-grid; ready for VPP (OpenADR/2030.5).
Purpose or Applications
Ideal for three-phase self-consumption in premium homes, offices, restaurants, workshops, and SMEs requiring 15 kW with HV battery, zero export, and fast backup for critical loads.
