Double Femtogrid Milestone for partner FocuS-E 28.05.2013 l Press Release FocuS-E BV, part of GE4ALL Nederland BV, has recently reached a double Femtogrid Milestone. So far, FcouS-E has sold 1250 pieces of the Femtogrid Solar Power Optimizer PO300. These units have been utilized in installations in the Netherlands, Belgium, Germany, France, the United Kingdom, Slovenia, and Turkey. The majority of these 1250 pieces have been used for installations in the Netherlands with 8, 9, 10, 11, or 12 modules. For 50 installations in the Netherlands FocuS-E used Femtogrid Monitoring to monitor the performance of the total installation. My Femtogrid shows the energy generated per module, per inverter, and for the total installation and therefore offers full visibility about the overall performance of the installation for care-free service.
