German and Dutch Installation Manuals still pending from the manufacturer. UK: Please note that a slight adjustment was required on the G99 report which has resulted in S5-GC range temporarily losing their G99 approved status. The updated form has already been resubmitted to the ENA and is currently awaiting assessment.
The Solis 50kW S5 3 Phase 5x MPPT – DC is a powerful and flexible grid-tied solar inverter designed for medium-to-large commercial solar installations, offering advanced performance, multiple MPPT tracking, and robust protection features. Built to deliver up to 55 kW AC output power while handling up to 75 kW of DC input, this inverter is ideal for businesses, warehouses, and larger rooftop photovoltaic projects where reliability and efficiency are paramount.
One of its standout features is the five independent MPPT (Maximum Power Point Tracking) channels. Each MPPT supports two string inputs, which helps reduce mismatch losses and improves energy harvest when solar arrays face different orientations or shading conditions. This design gives installers greater flexibility when laying out panels and maximises overall system efficiency.
The Solis 50kW S5 inverter boasts excellent conversion efficiency, with a maximum of about 98.7 % and strong European efficiency ratings, ensuring the majority of captured solar energy is converted into usable grid power with minimal loss. Its wide DC input voltage range — from an ultra-low startup voltage of 195 V up to a maximum of 1100 V — supports various PV configurations and enhances performance across diverse weather conditions.
Durability and safety are core aspects of the design. The unit carries an IP66 ingress protection rating with C5 anti-corrosion level, making it suitable for harsh outdoor and industrial environments. Built-in protections include Type-II surge protection on both DC and AC sides, AFCI (arc-fault circuit protection), and DC reverse-polarity protection to safeguard both the inverter and connected solar equipment. An integrated DC switch provides simple and safe PV disconnect for maintenance or emergency shutdown.
For monitoring and system communication, the inverter supports PLC, GPRS, and Wi-Fi connectivity, allowing remote performance tracking, diagnostics, and configuration via platforms like SolisCloud, which simplifies maintenance and improves system uptime.
Overall, the Solis 50kW S5 3 Phase 5x MPPT – DC inverter combines high efficiency, flexible MPPT design, and strong safety protections. It’s a compelling choice for commercial Pv systems that require robust performance, intelligent energy optimisation, and long-term reliability.
