Product Description

The Solis S6-GR1P5K-DC is a 5kW single phase grid-tie inverter for residential PV systems. It combines dual MPPT tracking, IP66 weatherproofing and built-in AFCI arc-fault protection, making it a well-specified option for UK and European rooftop solar installs.

Key features of this grid tie inverter

  • Rated output, 5kW, with 97.7% peak efficiency
  • Dual MPPT, up to 16A input current per string
  • Module compatibility, works with high-efficiency and bifacial panels up to 660W
  • Weatherproofing, IP66 rated for outdoor mounting
  • Safety, integrated AFCI arc-fault circuit protection (activation required)
  • Grid control, zero export power function, G98/G99 compliant

Product overview

The MPPT voltage range runs from 90 to 550V, with a maximum input voltage of 600V and a 120V start-up voltage. Each of the two MPPT trackers takes up to 16A, so it pairs well with current high-output panels.

Power factor stays above 0.99 and THDi below 3%, giving clean AC output to the grid. The transformerless design keeps the unit down to 8.9kg, which helps with wall mounting.

AFCI monitors for DC arc faults in the array. Zero export control lets the inverter be set to stop energy flowing back to the grid, useful where export is restricted or the tariff is import-only.

Applications

  • Residential rooftop grid-tied solar PV systems
  • Small commercial rooftop installations
  • New build and retrofit solar projects across the UK and Europe
  • Systems using high-efficiency or bifacial modules

Installation and safety notes

This inverter must be installed by a qualified electrician or MCS-accredited solar installer. DC wiring, AC connection, grid protection settings and commissioning must follow G98 or G99 requirements as applicable, alongside IET Wiring Regulations and DNO notification procedures. This is not a DIY installation.
