The efficient energy management system from Bosch allows solar power to be used to its optimum
potential for own consumption – this creates independence from electricity purchased from the public
power grid, thereby significantly reducing the electricity bill. The combination of inverter, storage solution and heat pump maximises own consumption, as PV power supports the heating of hot water.
