Product Description
The Solax IES 12000W X3-IES-12K Three-phase Hybrid Solar Inverter combines power, storage, and fast backup for demanding residential projects and SMEs. With an IP66 enclosure, two independent MPP trackers, and high-voltage battery management, it allows prioritization of self-consumption, storage of surplus, and supply of energy to critical loads thanks to EPS switching <10 ms. Its high-efficiency electronics (≈97.6%) and integrated export control simplify regulatory compliance and maximize savings. Everything is managed from SolaX Cloud, with guided commissioning, 24/7 monitoring, and remote maintenance.
Main Features
- 12 kW three-phase stable output for premium homes and businesses with medium-high demand.
- 2 MPPT (up to 4 strings) to optimize rooftops with different orientations and inclinations.
- EPS <10 ms to maintain IT systems, lighting, or refrigeration during a grid outage.
- HV battery 120–800 V with intelligent bidirectional management and configurable minimum SOC.
- Export control (zero feed-in), time-of-use (ToU) scheduling, and outputs for smart load.
- PV efficiency ≈97.6%, low THD, silent operation, and OTA updates.
Advantages or Benefits
- Higher annual savings: prioritizes self-consumption and discharge during expensive hours.
- Service continuity: almost instantaneous backup for critical loads without a generator.
- Flexible design with two MPPTs that reduce losses from shading and mismatch.
- Professional safety: IP66, SPD Type II on DC/AC, anti-islanding, and RCMU.
- Advanced management: history, alarms, and full control from SolaX Cloud (web/app).
Purpose or Applications
Three-phase self-consumption with battery in high-consumption homes, restaurants, offices, shops, and workshops. Ideal when zero feed-in, integration of heat pump or EV charger, and protection of sensitive loads are required.
