Sofar 4.0KTLM-G3: The connected solar inverter for a smart home
The new G3 single-phase inverter with 2 MPPT trackers for residential PV systems
SOFAR 3K...6KTLM-G3 is the upgraded version of SofarSolar's residential inverter series. With its elegant IP65 design and natural cooling for silent operation, the inverter is perfectly suited to small residential installations.
The inverter is also equipped with two MPPT trackers and an integrated I-V curve scanning function, making it possible to realize more complex installations, for example those with shading problems or different roof orientations.
A WiFi key is supplied with the inverter, for easy connection to the SofarSolar monitoring portal.
