The engage solar kit is perfect for solar/PV installation as it gives you a guide of how your consumption compares with your generation. Efergy's engage hubs are simple to install and use. A small sensor is clipped on to the supply cables in your breaker panel and another onto the cable coming from your solar panel inverter. A lead from the sensor is connected to the efergy transmitters, which then wirelessly sends real time data to the engage hub. The engage hub is connected to your internet router via Ethernet cable. When you go online to Efergy's web portal or onto your smartphone app, the router wirelessly uploads your energy data and converts this data into kilo-watt hours. The web platform or app will then show you how much energy you are using in the same units that are on your bill. You can also see how much energy you are generating compared to what you are consuming.
