Overview
Solis S6-EH3P (60–75 kW) is an ultra-high-power three-phase high-voltage hybrid inverter for industrial and C&I applications. The series is intended for large industrial enterprises, factory workshops, agricultural complexes, data centres, logistics parks and shopping centres with energy-intensive infrastructure. The model is engineered to work with large-capacity industrial high-voltage battery systems. The high battery bus voltage minimises current losses in the cable run, raises system efficiency and delivers extremely high charge/discharge currents for rapid energy capture from the grid or a generator.
The inverter is engineered for large-scale PV arrays: an extended number of MPPT trackers (up to 10 MPPTs) handles high currents and delivers maximum compatibility with modern high-power bifacial PV modules. Switchover to backup power in under 10 ms keeps production processes uninterrupted, while a high overload capability confidently starts powerful industrial motors, pumping stations and refrigeration equipment.
Solis S6-EH3P (60–75)K10 supports cascading, integration with industrial diesel generators, Zero Export and peak shaving, plus dynamic reactive power compensation to reduce grid stress.

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.
