- Vendor: Solax
Specifications
Product Description
The Solax Solar Inverter 8000W X3-PRO-8.0K-G2 Three-phase is the professional 8 kW solution for low-voltage three-phase self-consumption installations that require reliability, performance, and advanced connectivity. Its state-of-the-art power electronics, dual MPPT tracker, and IP66 enclosure ensure efficient and safe conversion on rooftops with two orientations or partial shading. The X3-PRO G2 series stands out for its 150% DC oversizing and the ability to deliver 110% AC to cover irradiance peaks, as well as a wide MPPT tracking range and low start-up voltage that maximize energy capture from the early hours of the day.
Main Features
- 2 MPPT with a wide operating range (approx. 160–980 V) and low start-up voltage (≈200 V) to capture more energy.
- 32 A per MPPT (up to 2 strings per MPPT) and Isc 40 A, optimal for high-current TOPCon/HJT modules.
- Maximum efficiency of 98.2% and Euro efficiency close to 97.7% for higher energy yield.
- IP66, Type II SPD on DC and AC, residual current detection, anti-islanding, and AFCI (optional) for advanced safety.
- Photovoltaic DC oversizing of 150% and output overload of 110%.
- Master/Slave parallelization, global MPP scanning, and 24 h maintenance/monitoring (optional) with SolaX Cloud.
Advantages or Benefits
- Higher annual production thanks to the wide MPPT range and high current acceptance per tracker.
- Safer installations: IP66 and SPD on both sides reduce risks from dust, water, and overvoltages.
- Versatile designs on rooftops with two orientations, unbalanced strings, or partial shading.
- True scalability without oversizing electronics: 150% DC and 110% AC absorb peaks and future expansions.
- Integrated export management for zero feed-in or power limits according to distributor regulations.
Purpose or Applications
Focused on residential three-phase self-consumption with high demand, small businesses, offices, and SMEs. Especially suitable when using high-power modules and requiring export control, remote maintenance, and silent operation.
