You can also make a meaningful upgrade to your PV system by adding other power generators. In addition to small wind farms or hydroelectric power plant, diesel generators ensure that your energy demand is covered in the event of poor weather or if your stores are empty. Energy control plays a key role when it comes to an off-grid energy supply. SMA technology therefore ensures that all components are compatible with one another and that the storage system is optimally used. If more solar power is available than needed, then the batteries will be charged. If demand is greater than production, it is covered by the electricity stored in the batteries.
