Overview
Solis S5-GC (25–40 kW) is a commercial-class three-phase grid-tied inverter for solar power plants built for self-consumption or the feed-in tariff. It is the optimal choice for enterprises, warehouse complexes, shopping centres, vehicle service stations and private households with high consumption.
The device operates without batteries, converting solar energy directly into three-phase AC power for the site. This substantially reduces daytime grid electricity costs and ensures a fast payback without investing in expensive batteries.
The inverter has 3 or 4 independent MPPT trackers (depending on power rating) supporting input currents up to 32 A per MPPT. This ensures compatibility with large-format high-output PV modules and allows flexible module placement on roofs with complex geometry or mixed orientation.
Solis S5-GC offers efficiency of up to 98.5%, a low start-up voltage and a high IP66 ingress protection rating. It features arc-fault protection (AFCI), surge protection on the DC/AC sides, and supports Wi-Fi/GPRS monitoring and export limitation (Zero Export).

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.
