Solis Inverter S6 50kW Hybrid Inverter 3 Phase

Solis Inverter 50kW Three-Phase HV Hybrid Inverter

The Solis S6-EH3P50K-H is a commercial and industrial-grade three-phase hybrid inverter delivering 50kW of continuous AC output for large rooftop, ground-mount, and C&I solar energy systems. With four independent MPPT inputs, compatibility with high-voltage battery systems from 150V to 800V, and support for PV arrays up to 96kW, it is purpose-built for South African businesses, farms, and large facilities where dependable power delivery, load-shedding resilience, and energy cost reduction are business-critical priorities.

NRS 097-2-1 certified, IP66 rated, and scalable to 300kW in parallel, the Solis 50kW HV Hybrid Inverter is the proven C&I energy management hub for South Africa’s most demanding solar installations.

50kW Three-Phase Output with 4-MPPT Solar Input

• Rated Output: 50kW continuous three-phase AC output (3/N/PE, 380V/400V). Four independent MPPT inputs allow solar arrays across multiple roof sections, orientations, or ground-mount rows to be independently optimised — maximising energy harvest and system flexibility for large commercial sites.

Max 96kW PV Array — 1,000V Max Voc

• PV Input: Accepts up to 96kW of solar input across 4 MPPTs (2 strings each, 8 strings total), with a maximum open-circuit voltage of 1,000V and an MPPT operating range of 150–850V. The high Voc ceiling supports long string runs and large commercial array configurations without additional combiner equipment.

High-Voltage Battery Compatibility — 150–800V, 140A

• HV Battery System: Compatible with high-voltage lithium-ion battery systems in the 150–800V range, including leading HV battery platforms from BYD, Pylontech, Dyness, Sunwoda, and others. Two independent battery ports support a combined 140A charge/discharge current (70A per port) via CAN/RS485 communication. Note: this inverter requires a high-voltage battery system and is not compatible with 48V LV batteries.

Sub-10ms Backup Switching & 160% Short-Term Overload

• Backup Performance: Switches from grid to backup in under 10ms — effectively uninterruptible for critical commercial equipment. Delivers 160% of rated power (80kW) for 2 seconds during backup, enabling reliable three-phase restart of motors, compressors, HVAC systems, and other high-inrush loads.

Scalable to 300kW — Generator Integration & Peak Shaving

• System Scalability: Up to 6 units can be operated in parallel for a total system capacity of 300kW, with larger deployments up to 500kW supported via the Solis STS distribution cabinet. Generator integration supports a wide input range (10–50kW) with automatic start/stop control. Built-in peak shaving reduces maximum demand charges for commercial tariff customers.

7-Inch LCD, Bluetooth & SolisCloud Smart Monitoring

• Monitoring & Control: 7-inch LCD display with Bluetooth, CAN, RS485, and Ethernet communication. Integrates with the SolisCloud platform for AI-assisted energy management, real-time performance monitoring, remote fault diagnostics, and OTA firmware updates. Optional Wi-Fi, cellular, and LAN modules available.

IP66, NRS 097-2-1 & 5-Year Warranty

• Compliance & Protection: IP66 rated for outdoor installation in harsh industrial and agricultural environments. NRS 097-2-1 certified for South African grid connection. 5-year manufacturer’s warranty, extendable to 10 years. Operating temperature: -25°C to +60°C. Dimensions: 530×880×290mm, 73kg.
