SMARTFORMER for SUNNY ISLAND

SMARTFORMER for SUNNY ISLAND

Set up split-phase grids – easier than ever

The Smartformer is the complete solution for off-grid and backup plants of up to seven kilowatts. At the same time, it acts as a AC distributor and a 120/240-volt autotransformer. The transformer provides step-up and step-down options to supply loads with 120 V and 240 V using a Sunny Island and a Sunny Boy – with a high level of efficiency over the entire power spectrum. Thanks to the pre-wired bypass function, the PV plant can be bridged without problems via a robust switch for maintenance work. The optimized transformer overload protection and a load-shedding contactor provide extra protection to the system. The Smartformer makes the stand-alone power supply simple and reliable.
