Thanks for the response. I'm no expert in this so I guess terminology could be an issue. Let me rephrase the question; Leading from the discussion in this thread, I would like to know if the Growatt can supply excess power generated from the solar array, back to the DB board so that this power can be used for none essential loads. My supplier stated that all bi-directional inverters perform this function and that was the definition of 'bi-directional'. I was under the opinion that the Growatt SPF 5000 ES 5kVA inverter was actually an off grid system and therefore did not feed back excess power to the DB board. I just would like to know if the Growatt can feed excess power back to the DB board.

It's where the inverter will supply excess power from you solar panels back to your DB board. In this situation, your none essential loads can receive power from the grid and the inverter.

Hi Everyone. I'm now really confused. I own a Growatt SPF 5000 ES 5kVA inverter and my understanding is that it's not a bi-directional inverter. I contacted my supplier and they told me it is! Could someone with more knowledge please confirm this. Thanks everyone.
