Because of the fundamental uncertainties inherent in microgrid design and operation, researchers have created battery and microgrid models of varying levels of complexity, depending upon the purpose for which the model will be used.
For example, if a battery is replaced when it falls to 80% of original capacity and microgrid operation requires a certain battery capacity, the battery must initially be oversized by 25% to maintain the desired capacity at the end of the battery’s life.
In such off-grid power systems, battery management is best done through the use of a microgrid controller and an energy monitoring platform. Elum Energy provides a wide range of solar products and ePowerControl MC and ePowerControl PPC along with our monitoring platform ePowerMonitor are best suited to perform these tasks effectively.
