If I have an existing inverter (6KW) which is a grid tie system, can I add another inverter to the system, say a balcony system? Is it just like two pumps, and both will push to the grid any excess electricity? We have west facing solar panels and just a few east or south facing ones would cover our morning usage of power. Thinking of adding another 1KW, although maybe even stick to 600w if there is some advantage (Germany).
