Solis S6 50kW Quad MPPT 3-Phase Grid Tie Inverter

Product Overview

The Solis S6 50kW Quad MPPT 3-Phase Grid Tie Inverter converts solar generation into three-phase AC power for grid-connected commercial, agricultural and industrial premises. Four independent MPPTs and support for up to eight PV strings provide flexibility when designing an array, while the IP66 enclosure supports demanding installation environments.

Key Features

• 50kW three-phase output for larger grid-connected solar power systems.
• Four MPPTs with up to two strings per tracker support flexible array layouts.
• Up to 42A input current per MPPT and 21A per string, as specified in the South African flyer, accommodate higher-current PV modules within the inverter limits.
• Maximum efficiency of 98.6% helps reduce conversion losses.
• Integrated DC switch and Type II surge protection on both AC and DC sides simplify system protection planning.
• Intelligent string monitoring and I-V curve scanning assist with performance checks and fault diagnosis.
• Dual independent RS485 ports support communication with multiple monitoring devices.
• LED indicators, Bluetooth and app access support local commissioning and status checks.

Applications

• Commercial rooftop solar installations with a suitable three-phase grid connection.
• Farm and agricultural premises using daytime solar generation.
• Industrial premises and larger grid-connected solar arrays.

Why Choose This Product?

This Solis S6 inverter combines a 50kW output with four independent trackers, high-current PV inputs and integrated monitoring. It is a practical option for professionally designed three-phase installations where array flexibility, conversion efficiency and accessible diagnostics are priorities.

Important Notes

• This is a grid-tied PV inverter. It has no direct battery connection and does not provide standalone backup power during a grid outage.
• Installation and commissioning must be completed by a qualified installer or electrician. Confirm local utility requirements and approval for the exact model before connection.
• PV string voltage and current must remain within the supplied inverter's limits across the expected operating conditions.
• AFCI and nighttime PID recovery are marked optional in the South African technical table. Confirm the supplied configuration before relying on these functions.
• Wi-Fi and GPRS monitoring are optional. Confirm the required communication accessories separately.
• Specifications below follow the South African flyer V2.1. The older European manual lists different enclosure dimensions and lower DC current limits. Verify the supplied hardware revision and nameplate before finalising mounting, cabling or string design.
• Standard warranty is 5 years; any extension is subject to supplier availability, registration and applicable terms.
