Overview
Solis S6-GC3P (40–60 kW) is a new-generation three-phase grid-tied inverter (sixth S6 series) for large-scale commercial and industrial solar power plants. The model optimises business energy costs by offsetting self-consumption or selling energy under the feed-in tariff. It is an effective solution for plants, factories, logistics terminals, agricultural complexes and retail and entertainment centres.
The device feeds solar generation directly into the site's three-phase network without using batteries, offsetting daytime consumption peaks and ensuring a fast return on investment.
The S6 series stands out for its expanded number of independent MPPT trackers (up to 5-6 MPPT depending on the power rating) with increased current capacity per string. This guarantees full compatibility with today's high-power bifacial solar modules and allows PV arrays of complex geometry to be built across roof planes with different angles and orientations.
Solis S6-GC3P (40–60)K achieves efficiency of up to 98.7%, carries a high IP66 ingress protection rating for outdoor installation, and features arc-fault protection (AFCI) and Type II surge protection on the DC and AC sides, along with Zero Export (grid feed-in limitation) and remote monitoring via SolisCloud.

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.
