DCR are approved Solar Edge, Tesla and Sonnen battery installers. We have fitted lots of batteries in London over the years and have many customers who are storing and re-using their surplus Solar PV Electricity every day.
Solar batteries reduce your reliance on the grid by storing your generated solar electricity for use when the sun is no longer shining and your Solar PV system has stopped producing electricity.
DCR are approved SolarEdge battery installation specialists. We receive regular training and product updates and work closely with SolarEdge to maintain the highest standards.
The SolarEdge 10KW Energy Bank sits perfectly alongside any new or existing SolarEdge system. The battery will integrate with the Solar Panels on the monitoring and management platform which can be accessed through a smart phone app or PC.
