The Solis S6-GR1P5K-S is a 5kW single-phase on-grid solar inverter with two MPPT trackers, 97.7% maximum efficiency, and an 8-year warranty. It accepts up to 7.5kW of PV input at a maximum 550V and weighs just 8.9kg.
5kW single-phase is the top of the home range, and the PM Surya Ghar subsidy applies. This is the rating larger homes settle on a house with air conditioning, a villa, or a family whose daytime consumption has outgrown a 3kW system. The subsidy is what makes the numbers work: tell our team your consumption and we will show you the net cost after subsidy and the payback period, not the sticker price.
How an on-grid system works. No batteries, nothing to replace in five years, nothing to maintain. The inverter converts DC from your panels to AC, powers your home through the day, and exports the surplus through net metering so your meter runs backward the credit offsets your night and monsoon consumption. It is the simplest solar configuration and the shortest payback.
7.5kW of PV input on a 5kW inverter. That 1.5:1 ratio lets you build a larger array than the nameplate suggests. Panels rarely hit rated output in real conditions, so an oversized array generates through more of the day more in the early morning and late afternoon, and better under monsoon cloud. On a home roof with the space, that headroom converts into real extra units across the year.
At 8.9kg, the lightest inverter in the Solis range. That matters more than it sounds for a home installation: a light wall-mounted unit needs no special provision, mounts on an ordinary utility or external wall, and is straightforward for an installer to handle alone. Compare that to the 21.6kg of the equivalent 5kW hybrid the on-grid unit is less than half the weight because it carries no battery management.
Two MPPT trackers. Each handles 16A operating current (22A short-circuit) across a wide 90-550V range, so a roof facing two directions, or with afternoon shading from a water tank or parapet, still generates properly each string managed independently rather than dragged to the weakest. Most 5kW home inverters run a single tracker; two is a genuine advantage on the irregular rooftops most Indian homes have.
The 8-year warranty. Most inverters in this class ship with 5 years standard. Eight years is three additional years on the component most likely to fail before your panels do.
500W. Tell our team your monthly bill and roof layout and we will confirm 5kW is right, or point you to the 3kW below it.
SolarClue is India's managed solar marketplace. Our team confirms this inverter matches your panel array, your single-phase supply and your DISCOM's net metering requirements before you order, and handles your PM Surya Ghar subsidy application end to end so the 5kw solar system price you pay is the net figure after subsidy, not the sticker. If you are on three-phase supply, the three-phase 5kW Solis is the unit you need instead; tell our team your connection type. You book with a token payment rather than the full amount upfront. Supply and installation are coordinated through verified partners, and we handle Solis warranty support afterwards.
