isolated energy system

The FlexCombo-M250 district microgrid solution consisted by isolated energy storage modules, can extend and alleviate or even eliminate the demand for transformation and upgrading of power transmission and distribution facilities due to the sharp increase in the total power load of islands or urban blocks by peak load shaving. It allows users in islands and blocks to obtain strong voltage support and high-quality power quality at a small cost; it can also improve the local acceptance capacity of distributed energy and support the independent operation of island microgrids with the combination of solar energy technology.
