Homeowners looking to minimize their carbon footprint and reduce their energy costs often buy plug-in electric vehicles (PEVs) in tandem with solar panels. In most instances, any excess solar power produced is sent to the grid at a fixed price per kilowatt-hour or subtracted from the households’s overall power demand via net metering.
However, new residential chargers from electric vehicle (EV) charging equipment manufacturers Etrel and Circontrol have advanced load monitoring features that enable EV charging to automatically be timed with residential solar power production. Both companies exhibited their products at the recent eCarTec conference in Munich, Germany, which featured automotive companies, Tier 1 and Tier 2 suppliers, and EV charging hardware and software companies from across the globe.
Etrel, which hails from Slovenia, continues to impress me with its ability to stay at the forefront of EV charging management technology. When I first met with them nearly 2 years ago, the company had the most sophisticated backend EV software platform.
