Solis-255K-EHV-5G-PLUS 255kW Three Phase Grid-Tied Solar Inverter | 1500V High Voltage Commercial PV Inverter

12 Independent MPPTs, 99.0% Max Efficiency

Ultra-High Tracking Efficiency & Flexible PV Configuration

This 255kW inverter comes with 12 independent MPPT controllers supporting 24 PV strings, reaching a maximum efficiency of 99.0% and EU efficiency of 98.8%. It allows a DC/AC ratio up to 150%, compatible with high-power 550W+ bifacial solar modules, delivering superior power tracking density at 47MPPT/MW. The 480–1500V wide MPPT voltage range adapts to complex shading and long-distance wiring layouts, maximizing energy harvest all day long.

Smart Grid Support & Intelligent Monitoring Functions

Built-in professional auxiliary grid optimization features differentiate this model from standard inverters. The Night SVG function provides reactive power compensation after sundown to stabilize local grid voltage. Real-time intelligent string monitoring and automatic I-V curve scanning quickly locate faulty panels or strings to reduce maintenance downtime. Remote firmware upgrade via RS485 or optional PLC power line communication eliminates on-site visits for software updates.

Comprehensive Safety & Low Maintenance Design

The unit adopts a fuse-free DC architecture to remove routine fuse replacement work, realizing maintenance-free operation. Integrated nighttime PID recovery reverses potential induced degradation of solar panels to sustain long-term power output. Full protection suite includes DC reverse polarity, short circuit, overcurrent, surge, anti-islanding and over-temperature protection, with DC Type II and AC Type II surge protection pre-installed. All core components are premium global brands for extended service life.

Rugged Outdoor Industrial Hardware

With IP66 dustproof and waterproof enclosure, the inverter operates reliably in extreme ambient temperatures from -30°C to +60°C, supporting up to 100% non-condensing humidity and a maximum installation altitude of 4000 meters. Intelligent variable-speed fans optimize cooling while lowering standby power consumption to under 2W at night. The transformerless topology reduces weight and losses; the whole unit weighs 113kg with compact 1125×770×384mm dimensions. It uses MC4 DC connectors and OT terminals for AC cable up to 300mm², paired with an on-board LCD screen for local parameter viewing.
