The SnapINverter mounting system makes inverter installation and servicing done easily. After fitting the wall bracket and cabling for the device, the inverter is placed in the wall bracket before being swivelled into position and secured. Allows for sustainable service for the lifetime of the system.

This transformerless single phase inverter is ideal for residential applications. Several integrated features, which make it stand out from competitors, include dual powerpoint trackers, high system voltage, a wide input voltage range and unrestricted use indoors and outdoors.
