Based on the weather forecast and consumption analysis, the Solar-Log energy management system determines the most effective charging times for the battery storage system. The battery charging is automatically controlled by the Solar-Log with the goal of preventing generated energy from being wasted and of having the battery 100 percent charged by the end of the day, says SDS.
Unmanaged battery systems check the energy flow direction at the feed-in point and start charging the battery when power is being fed into the grid. In this case, the Solar-Log visualizes and documents the battery system's charging processes, explains SDS. The new forecast-based charging means that battery storage charging can now be intelligently controlled by the Solar-Log for more effective use of the PV plant's power curve. This function is especially important for subsidized plants.
In addition to the weather forecast data, the local consumption data is incorporated into the battery control management. The Solar-Log knows the typical past consumption data and checks if the calculated charging times are enough to charge the battery to capacity, SDS says. The charging times are adjusted as needed.
