[QUOTE="johnb2713, post: 535700, member: 35153"] Theres some room for losses and inaccuarcy here, what was the DC voltage at the inverter under these conditions? Thats a good move, it will be interesting to hear what they say / find. You will never get it to zero especially with zero export set. They always hover around zero but due to the digital nature of inverters each change is a step. It's possible that at one point to have 5w of import and when it adjusts it's voltage the next step gives it 10w of export. It may not have a step where it can hit zero. By setting export to zero, the inverter will always stay on the side of import so cant average out the export and import (well thats how the Growatt logic seems to work). [/QUOTE]
