Page 7: Explanation Of Symbols
Islanding is a condition when grid connected PV/ batteries back feed energy into the Grid when Grid is turned off for maintenance work, putting maintenance personal at serious risk. Flex HV-EU series inverters prevent islanding through Active Frequency Drift (AFD). -
Page 8: Introduction
3.1 Basic features The Flex HV-EU Series hybrid inverters are designed to work with PV modules, battery, mains supply and electrical loads. Hybrid inverter helps to optimize on-site consumption, charge battery with surplus PV energy and supply energy from battery to meet load. - Page 9 On site consumption of PV energy is the highest priority. Excess generation is used to charge batteries, and finally export to grid. Work mode: Feed in Use Priority: PV generated energy to a. Meet load b. Export to grid c. Charge battery Figure 3-3 Feed in Use Mode This mode is preferred for areas with Feed-in Tariff.
