The site mapper allows SolarEdge installers to streamline the registration of a new system by mapping its physical layout in the SolarEdge cloud-based monitoring platform. This application is integrated with the SolarEdge monitoring platform and enables the following functionality: • Simple onsite registration of new systems. • Creation, editing and on-site verification of system physical layout. • Scanning and assigning SolarEdge power optimizer serial number to the right location in the system physical layout. • The scanning can be done by utilizing the mobile device’s integrated camera or with an external Bluetooth connected scanner. • Working off-line with no data connection. The data is stored locally on the mobile device and allows data synchronization with the SolarEdge monitoring platform when data connection is available.

PV Optimizer & Solar compass is a tool intended to maximise the output of your solar panels. To use the optimiser you only need to choose between one of the 4 time frames available (if you pretend to adjust your panels for the moment, every 3 months, 6 months or yearly), place your device above your panels, and adjust its azimuth and tilt according with the values given by the app. PV optimizer's algorithm will make sure you get the most from your panels and don't waste any opportunity to increase your output. This app also comes with a solar compass which you might find useful for optimizing your panels or for other activities, with plenty of real time data regarding solar position and radiation. In version 2.0 we are proud to present you a forecast for your solar panels output. Just input your panel capacity, tilt and azimuth angles, and you'll get a forecast for the monthly energy you might generate in theory. All the functionalities of this app are completely free.
