Siemens, in partnership with 1st Light Energy, has installed its M250 solar microinverters and VersiCharge universal electric vehicle (EV) charging unit for residential use, resulting in a zero-emission home energy environment.
The company says the advanced microinverters are its most efficient and improve the effectiveness of the residential PV solar installation. In conjunction with the solar array installed by 1st Light Energy, the system can deliver enough electricity for a home to achieve net-zero energy consumption. Net-zero energy consumption means the total amount of energy used in the home is equal or less than the power generated by the on-site renewable sources.
“Siemens microinverters paired with intelligent EV charging infrastructure, like the VersiCharge universal unit, is a powerful combination for today’s zero emission households,” says Barry Powell, head of Siemens Low Voltage and Products.

Siemens M250 solar microinverters are installed beneath each PV solar panel and convert dc to ac power. Each microinverter ensures the maximum power available from each PV solar module is transferred to the home or back to the utility grid regardless of shading or orientation of specific panels. The microinverters can be installed in multiple orientations with different module brands and wattages. The new M250 microinverters feature integrated grounding, saving money on labor and raw material costs, and also come with free monitoring, which allows both the contractor and homeowner visibility to the array, saving money on annual maintenance.
The installation also included the first residential demonstration of Siemens VersiCharge universal unit for electric vehicle (EV) charging, a unit that features shorter EV charging times that result in greater energy savings. The VersiCharge universal unit also includes a delay feature allowing homeowners to charge at off-peak utility rates. The unit can be installed either indoors or outdoors by a simple, removable bracket for use in multiple locations.
“The microinverters have given us more flexibility in our designs that we cannot normally get with string inverters,” says Justin Krum, CEO of 1st Light Energy.
