Overview
Solis S6-GC3P (25–36 kW) is a new-generation three-phase grid-tied inverter (sixth S6 series) for building commercial solar power plants. The model is designed to cut electricity costs by offsetting a company's self-consumption or by operating under the feed-in tariff. It is ideal for medium-sized production sites, warehouse complexes, vehicle service stations, hotels and commercial buildings.
The inverter converts generation from the PV modules directly into the site's three-phase grid without any battery bank. This makes the system exceptionally reliable and shortens the return-on-investment period.
The S6 series features an improved architecture: 3 or 4 independent MPPT trackers supporting increased input current per string, enabling operation with the most powerful modern solar modules (600+ W) and efficient PV array layouts on complex roofs with mixed orientations.
Solis S6-GC3P stands out with maximum efficiency of up to 98.5%, a low start-up voltage for a longer working day, IP66 ingress protection, integrated arc-fault detection (AFCI), Type II surge protection on the DC and AC sides, Zero Export to limit generation fed into the external grid, and intelligent SolisCloud monitoring.

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.
