Data loggers
Solis S3-Logger data logger
Solis S3-Logger (S3-Logger / S3-Logger-EPM) is a new-generation industrial data logger for centralised monitoring and management of commercial and utility-scale solar power plants. It supports up to 80 inverters and includes an integrated EPM (Export Power Management) function for precise grid export limitation.

Overview
Solis S3-Logger is a high-performance system data logger and energy management controller engineered for commercial (C&I) and industrial photovoltaic plants. It is available as the standard S3-Logger and as the S3-Logger-EPM with extended export power control functions.
The device supports group connection of up to 80 Solis inverters over an RS485 bus (Modbus RTU/TCP) and guarantees uninterrupted data transfer to the SolisCloud platform via Ethernet (LAN), 4G or Wi-Fi. The EPM version enables effective real-time export limiting (Zero Export), reacting to changes in site load within fractions of a second.
The S3-Logger supports open industrial protocols (SunSpec, Modbus), making it easy to integrate into external SCADA supervisory systems and energy management systems (EMS). The logger is housed in a rugged enclosure for DIN-rail or wall mounting, offers ample internal memory for log storage and supports over-the-air (OTA) firmware updates for every connected inverter.

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.
