Overview
Solis S6-GR1P (2.5–6 kW) is a single-phase grid-tied inverter for residential and commercial solar power plants running on self-consumption or the feed-in tariff. It is the optimal choice for cottages, houses, offices and small businesses with standard daytime energy consumption.
The device operates without batteries, directing the generated solar energy straight to your equipment. This significantly reduces grid electricity costs and ensures a fast return on the system without investing in expensive batteries.
The inverter has 2 independent MPPT trackers supporting input currents up to 14 A per string. This makes it easy to place PV modules on two different roof pitches (east–west, for example) and guarantees full compatibility with modern high-output PV modules.
Solis S6-GR1P features a low start-up voltage, so generation begins early in the morning and continues late into the evening. The unit uses silent passive cooling, includes arc-fault protection (AFCI) and supports Wi-Fi monitoring and grid export limitation.

Frequently asked questions
-
Start from the site's average daily consumption and the peak load the inverter has to carry in off-grid mode. The power range of each modification and the recommended PV array size for it are listed in the product card under "Key specifications" — for a precise selection, contact a Solis dealer or use the form below.
-
The list of validated batteries is published on the product page — in the compatible-equipment section, where one has already been compiled for that model. The voltage range (LV or HV, depending on the series) is stated in the technical specifications either way. If there is no list, or the battery you need is not on it, contact the Solis Ukraine technical department — compatibility should be confirmed separately.
-
Most Solis hybrid and off-grid inverters support connecting a generator with automatic start-up when the battery is discharged. Whether a specific model has this function, and how it is wired, is stated under "Key features" and in the "Technical specifications" table of the product card.
-
It depends on the series: single-phase models are designed for a 220 V grid, three-phase models for 380/400 V. The exact connection type for a given product is stated in the "Grid phases" card under "Key specifications".
-
Solis equipment carries the manufacturer's warranty, which in Ukraine is administered by official dealers and authorised service centres. The exact term and conditions are stated on the warranty card and on the device's rating plate — for registration and the claim procedure, see the Support section.
