All operators of private photovoltaic systems are familiar with the situation: The solar power produced during the day is fed unused into the public mains and expensive power must be purchased from the power supply company in the evening because there is no solar power available.
Energy management systems like the SOLARWATT EnergyManager offer solutions for this problem. It monitors, controls and regulates all energy flows in a household. The EnergyManager ensures that a maximum amount of solar power is consumed within the household in order to reduce the amount of mains power that must be purchased, thereby reducing energy costs.
