Overview
Solis S6-EH3P (80–125 kW) is the flagship megawatt-class three-phase high-voltage hybrid inverter for large industrial sites and the C&I sector. The series is intended for large plants, factories, logistics hubs, grain elevators, data centres and hypermarkets with critical power-continuity requirements. The inverter works with powerful high-voltage (HV) battery systems. The high battery bus voltage minimises resistive losses in the cabling, guarantees maximum efficiency and delivers high charge/discharge currents for rapid energy capture during short windows of grid availability or from diesel generators.
The model is built for large-scale PV arrays: 10 independent MPPT trackers with high input current support allow a large number of module strings to be connected on complex roofs or ground-mounted structures using modern bifacial PV modules. A 10 ms transfer to off-grid supply protects sensitive industrial equipment from disruption, while the high overload capability ensures confident start-up of powerful motors, compressors and pumps.
Solis S6-EH3P (80–125)K10 supports extended parallel operation of multiple units, full compatibility with industrial diesel generator sets, Zero Export and peak shaving, plus dynamic reactive power compensation.

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.
