Solis Three Phase 50kW High Voltage Hybrid Inverter

Solis S6-EH3P50K-H 50kW Three Phase High Voltage Hybrid Inverter

Model: S6-EH3P50K-H

The Solis 50kW Hybrid Inverter, produced and powered by Solis, offers robust and versatile energy solutions for both on-grid and off-grid applications.

The Solis S6-EH3P50K-H is a premium high-voltage, three-phase hybrid inverter designed for large-scale commercial, industrial, and high-demand residential energy storage applications. Built with cutting-edge technology, it delivers exceptional performance, versatility, and safety while supporting both on-grid and off-grid operation.

With 4 MPPTs and up to 8 PV strings (40A per MPPT), this inverter can handle up to 100kW of PV array capacity and 96kW of usable PV input on a wide MPPT range of 150–850V. It offers two independently controlled battery ports with a total charge/discharge current of 140A (70A+70A), supporting lithium-ion batteries from 150V to 800V.

Engineered for flexibility, it can operate as a grid-tied inverter without batteries or seamlessly integrate with battery storage for self-consumption, backup power, and peak shaving. Parallel operation of up to six units allows for massive scalability—up to 300kW backup load capacity.

The inverter delivers 1.6 times its rated output for 2 seconds to support heavy inductive loads and ensures uninterrupted power supply with a <10ms UPS transfer time. It also supports multi-input generator connectivity with automatic start/stop control.

Efficiency and reliability are at the core of its design, featuring 97.8% maximum efficiency, 98.5% PV-to-battery charging efficiency, and 97.5% battery-to-AC efficiency. Integrated AFCI (arc-fault circuit protection) provides an extra layer of safety, alongside comprehensive surge, overcurrent, short-circuit, and anti-islanding protections.

The IP66-rated enclosure ensures durability in harsh outdoor conditions, while intelligent fan cooling maintains optimal operating temperatures. The inverter comes with an LCD display, Bluetooth, app monitoring, and full Solis Cloud support for remote control and firmware updates.
