Maintain your solar energy supply — even when the sun is not shining
Sometimes, the sun delivers more power than you currently need. You would normally feed in the surplus power for a feed-in tariff that is considerably lower than the current electricity prices. Sometimes, however, solar power is not available when you need a lot of power – for example, if you want to charge your electric car overnight. This means that you would normally have to purchase expensive power from the utility grid. The SMA Energy System Home makes it possible to use a greater proportion of your own solar power.
