Specifications
Product Description
The Solax FORTH 80000W X3-FTH-80K-G2 Three-phase Solar Inverter is a high-performance industrial string inverter, designed to maximize energy capture on rooftops and ground-mounted plants with demanding availability and control requirements. With 9 MPP trackers, IP66 protection, and electronics optimized for warm climates, this 80 kW model delivers more kWh to the grid with simpler O&M thanks to intelligent I-V curve diagnostics and advanced monitoring.
Main Features
- 9 independent MPPT with 2 strings per tracker (18 strings in total) to reduce losses from shading and mixed orientations.
- Maximum efficiency of 98.6% and THDi <3% for clean and stable injection.
- 150% PV oversizing (up to 120 kWp) and 110% AC overload to maximize peak hours.
- MPPT range 180–1000 V, max. PV voltage 1100 V; current per MPPT 32 A (Isc 46 A).
- IP66 protection, SPD Type II on DC/AC (Type I+II optional) and optional AFCI.
- Cooling by intelligent fan and advanced thermal design for longer service life.
Advantages or Benefits
- Higher annual production thanks to 9 MPPT and up to 150% oversizing on DC.
- Industrial electrical safety with integrated SPD and weather-resistant IP66 enclosure.
- Efficient O&M: I-V diagnostics, string-level measurement, and remote configuration/updates.
- Project flexibility: integrated export control and compatibility with optional PLC.
- Lower LCOE: high efficiency, low harmonic distortion, and possibility of aluminum AC wiring.
Purpose or Applications
Ideal for three-phase self-consumption in industrial warehouses, logistics, agrivoltaics, and modular commercial plants in 80 kW blocks. Suitable for projects with multiple orientations or partial shading that require stability and high continuous performance.
