Overview
Solis S5-WiFi-ST is a new-generation data logger (S5 series) for wireless collection and transmission of solar power plant operating data. The module is available with two connector types (4Pin and USB), making it a universal solution for the entire Solis inverter range.
The device connects to the inverter on a Plug & Play basis, with no additional signal or power cabling required. The data logger automatically collects generation, voltage, current, battery status and fault data and transmits it to the SolisCloud platform over a home or corporate Wi-Fi network (2.4 GHz).
Solis S5-WiFi-ST features a UV- and moisture-resistant enclosure with a high ingress protection rating, internal memory that retains data if the internet connection drops temporarily, remote inverter firmware updates (OTA) and fast system configuration via the Bluetooth/Wi-Fi mobile app.

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.
