Solis Single Phase Grid-Tied Inverter: S6-GR1P(1-3)K-M

Small homes and compact rooftops don't need an inverter built for a load they'll never draw. The Solis S6-GR1P(1-3)K-M inverter is built specifically for this end of the market, a single-phase, grid-tied unit covering 1kW to 3kW, designed for straightforward, no-fuss solar on a small home or apartment rooftop. This page covers what the Solis S6-GR1P(1-3)K-M inverter actually offers, which model variant fits which home, and where to get current pricing.

Key Features

The Solis S6-GR1P(1-3)K-M inverter is built around a small set of design choices that matter more at this scale than a longer spec sheet would suggest:

• Max. efficiency of 97.1%, converting the large majority of DC input into usable AC output, which matters directly for how much of your panels' generation you actually get to use

• String current up to 16A, sized appropriately for the panel configurations typical of a small rooftop array without unnecessary headroom you're paying for and not using

• Super high frequency switching technology, part of what keeps the Solis S6-GR1P(1-3)K-M inverter compact without sacrificing conversion performance compared to bulkier legacy designs

• Wide voltage range and low startup voltage, meaning the inverter begins generating earlier in the day and continues later, rather than waiting for strong, consistent sunlight before it starts contributing

• Precise MPPT algorithm, tracking the optimal power point on the connected string even as conditions shift through the day, including partial cloud cover

• Compact and lightweight housing, straightforward to mount and handle during installation, which also keeps installation labor time down

• Friendly and adaptable grid connection, designed to work smoothly with standard grid-tied setups without complex configuration on the installer's end

Taken together, these features make the Solis S6-GR1P(1-3)K-M inverter a genuinely low-maintenance choice for a small system, there's less to go wrong mechanically, and the efficiency and MPPT design mean you're not leaving meaningful generation on the table just because the unit is entry-level in capacity.

Choosing the Right Model: 1K, 2K, or 3K

The Solis S6-GR1P(1-3)K-M inverter isn't a single fixed unit, it's available in three individual models within the same series: S6-GR1P1K-M, S6-GR1P2K-M, and S6-GR1P3K-M. The right one depends on your actual panel array size and expected daily consumption, not just your roof area or a rough guess.

A 1BHK apartment with light daytime load, lighting, fans, a refrigerator, typically fits the 1K or 2K variant of the Solis S6-GR1P(1-3)K-M inverter comfortably. A home with slightly higher consumption, an extra AC unit or a home office running through the day, is usually better matched to the 3K model in the same series. Your installer should confirm the exact fit based on your specific panel wattage and string configuration rather than sizing on square footage alone. It's worth resisting the temptation to just pick the largest variant in the Solis S6-GR1P(1-3)K-M inverter series on the assumption that bigger is safer, an oversized inverter relative to your panel array doesn't generate more power, it just means you paid for capacity you're not using.

Who This Inverter Is Built For

The Solis S6-GR1P(1-3)K-M inverter suits a specific, well-defined segment rather than trying to cover every home size:

• 1-2 BHK apartments and small homes with modest daytime consumption, lighting, fans, a refrigerator, and occasional AC use during the hottest parts of the day

• First-time solar buyers wanting a straightforward entry point without oversizing their first system before they have real generation data to plan a future expansion around

• Small offices or single-room commercial spaces looking to offset a light daytime electricity bill without a full commercial-scale installation

• Homes prioritizing partial bill offset rather than covering their entire consumption from day one, with room to add capacity later if needed

If your home regularly runs multiple ACs or heavy simultaneous appliance load, the Solis S6-GR1P(1-3)K-M inverter will only offset a portion of that, worth knowing before sizing your system around price alone rather than your actual consumption pattern. For that kind of higher-load home, a three-phase or higher-capacity residential model is usually the better fit, and your installer can help confirm which range your specific consumption profile actually calls for.

Pricing and Availability

Pricing for the Solis S6-GR1P(1-3)K-M inverter depends on the specific model variant you need, current input costs, and installation scope, so we don't publish a fixed number on this page. What we can tell you is that all three variants carry genuine manufacturer warranty support when sourced through an authorized channel, which matters more over a 25-year system life than a small difference in upfront price. Buying the Solis S6-GR1P(1-3)K-M inverter through an unauthorized reseller can put that warranty coverage at risk even if the unit itself is genuine, since manufacturers typically require a traceable, authorized purchase history to honour a claim.
