Solis 100kW 3-Phase Grid-Tied Solar Inverter | 5G Pro

The Solis 5G Pro 100kW is a transformerless three-phase grid-tied solar inverter built for commercial and industrial PV installations. It runs at up to 98.7% maximum efficiency (98.3% EU efficiency), using 6 or 8 MPPT trackers to handle up to 16 string inputs across large, high-density arrays.

Grid tied solar inverter features

• Rated output, 100kW, with a peak of 110kVA
• Efficiency, 98.7% maximum, 98.3% EU
• MPPT design, 6 or 8 trackers with up to 16 string inputs
• String input current, 36A maximum per string
• DC/AC ratio, above 150% for dense array layouts
• Enclosure, IP66 rated with intelligent redundant fan cooling

Night SVG lets the inverter supply reactive power compensation to the grid outside solar generation hours, which matters on sites with grid operator power factor requirements. AFCI arc fault protection and PID recovery are available as optional functions.

Why the 36A string current and 150% DC ratio matter

A 36A maximum string input current suits current high-output bifacial modules, which often produce string currents above 20A in real conditions. The 150% DC overloading allowance means a larger PV array can be connected against the inverter's AC rating, improving how much of the inverter's capacity gets used across the day.

Applications

• Large commercial and industrial rooftop solar systems
• Ground-mounted solar farms and utility-scale arrays
• Installations using high-output bifacial modules
• Sites with grid reactive power compensation requirements

Installation notes

Grid connection at this power level needs G99 compliance and a formal DNO application in the UK. Installation should be carried out by a qualified electrical engineer with commercial solar experience, with string design, array layout and protection coordination finalised before commissioning.
