Fronius Symo 15.0-3-M Lite is a three-phase string inverter designed for commercial and larger residential photovoltaic systems . This “Lite” model offers the core high-performance features of the Symo series while providing flexibility for communication setup, as it comes prepared for but does not include the pre-installed WLAN communication module .
Key Features:
-
15 kW Three-Phase AC Output: Ideal for commercial applications and larger residential self-consumption installations .
-
Dual MPPT Trackers: Two independent Maximum Power Point Trackers provide design flexibility for complex roof layouts with different orientations or partial shading .
-
SuperFlex Design: A wide DC input voltage range (200 – 1000 V) supports high-voltage PV strings and allows for significant oversizing of the PV array .
-
SnapINverter Technology: A modular design separates the connection compartment from the power unit, enabling faster installation and easier servicing .
-
Robust Build for Outdoor Use: With an IP66 protection rating, the inverter is built to last and is suitable for both indoor and outdoor installation .
-
Flexible Communication Ready: The “Lite” version is prepared for the addition of a WLAN module and includes other interfaces like Ethernet (LAN), USB, and RS485 for monitoring and integration .
