Overview
Solis PrimePower (109 kWh / 50 kW) is a highly integrated all-in-one commercial energy storage system (C&I BESS) developed to solve on-site energy challenges for small and medium-sized businesses. A single cabinet houses a 50 kW three-phase inverter (PCS) and a 109 kWh battery array, simplifying design, transport and installation.
The battery pack is built around premium Grade A+ LiFePO₄ cells distinguished by long service life (over 6,000 cycles), high chemical stability and thermal resilience. The system features intelligent climate control to keep battery temperature stable, plus a self-contained multi-level fire suppression system for maximum site protection.
Solis PrimePower 50 kW/109 kWh guarantees a rapid switch to backup mode when the grid fails, supports peak shaving and Zero Export, and integrates fully with PV modules and diesel generators. Convenient monitoring, diagnostics and parameter control are handled remotely through the SolisCloud platform.

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.
