Product Description

The Solis S5-GR3P17K-DC is a 17kW three-phase grid-tied solar inverter built for commercial installations. It reaches 98.7% maximum efficiency and uses two independent MPPT trackers spanning a 160V to 1000V range, with a 180V startup voltage that lets it begin generating earlier in the day.

Key features of this solis 3 phase inverter

  • Rated output, 17kW, three phase
  • Maximum efficiency, 98.7%
  • MPPT trackers, 2 independent, 160V to 1000V range
  • Startup voltage, 180V
  • String input current, 16A maximum
  • Enclosure rating, IP66
  • Standby consumption, below 1W

Product overview

The natural convection cooling design removes the fan failure risk associated with active-cooled inverters over long service life. In dusty environments such as agricultural buildings or industrial sites, fans accumulate debris and need regular cleaning; a fanless approach avoids that maintenance entirely.

A 180V startup voltage lets the inverter begin generating at lower irradiance than many comparable units, extending effective generation time either side of peak sun. On a UK site this can add useful output during spring and autumn mornings.

Applications

  • Commercial and industrial rooftop solar systems
  • Agricultural buildings and farm solar installations
  • Sites requiring low-maintenance fanless inverter operation
  • Installations with export limitation requirements

Installation notes

Three-phase grid connection requires G99 compliance and DNO notification in the UK. Installation must be carried out by a qualified MCS-accredited installer, and string voltage should be calculated under cold conditions to stay within the 1000V maximum input.
