German startup Wattando has developed a 2.46 kW rooftop PV system that may be straight linked to the house community by way of an present cable with out interfering with present electrical techniques.

“It’s a form of XL plug-in photo voltaic system,” Stefan Ulfert, co-founder of Wattando, mentioned. pv journal. “This is made doable by our Wattster administration system, which ensures safe and wi-fi radio communication on the level of connection to the grid and the house community.”

Boris Klebensberger, managing director and co-founder, mentioned that the administration system adjusts the feed-in in keeping with the requirements built-in with the overload safety of the cable.

The system is costlier than traditional PV installations. However, in lots of circumstances the AC connection will be carried out extra cheaply. For households that may solely profit from PV and residential storage with a non-invasive answer, the corporate believes that its answer is the one possibility.

Wattando recommends implementing techniques corresponding to zero-feed techniques.

“From our perspective, altering the meter is just not actually obligatory when there’s a zero feed-in, as a result of by setting the bodily or arithmetic zero we are able to keep away from feeding behind the meter,” mentioned Klebensberger. “What is vital from the client’s perspective is a balancing meter.”
