System monitoring at a glance Informative, compact and easy to operate: the Sunny Beam with Bluetooth looks good and is packed with innovative monitoring technology. The large graphic display shows you all the essential data at a glance: daily profile, current output, daily and overall energy yield. But there's more to the Sunny Beam than meets the eye: at the flick of a switch you can retrieve the performance data of up to 12 inverters, a monthly summary, the energy yield in euros or dollars or the saved quantity of CO2. The data from a minimum of 100 days' performance is stored within the device and can be uploaded to a PC via USB interface – no additional software is required. And in case of plant disruption, the Sunny Beam can be programmed to emit an audio signal.
