Below a schematic diagram (system architecture) of our semi off-grid solar system. Specific for the system is the management part
From all relevant components data is collected and transformed into statistical data and reports. A second function is the:
=> on/off switching of the outsite lights based on solar elevation (sunrise and sunset)
=> the electric boiler based on charge level of the batteries or aremote swicht to force the boiler on and
=> Swicht on/off the addional charger from Grid or Generator.
The charge level of the batteries is based on real amount of charge and discharge versus the capacity of the battery instead of voltage (not correct). Additional information can be downloaded from the download page.
