Yeah, we do that. Given that most home appliances use more than 800W (even in Eco modes) we often use more than our production. E.g. our washing machine uses 1000W over a prolonged period of time which would be perfect to run on a sunny day. But it does so by switching the 2000W heating element so it averages to 1000W ... So we repeatedly export 800W (without any form of reimbursement) and import the missing 1200W back. And that is the case for all of our appliances. (I have a sensor to monitor that) Don't know if more modern machines are better in this regard, our machines are about 5 years old now. edit: I don't want to sound bitter about it. The Balkonkraftwerk works perfectly fine to power our base energy load.
