Henkg Posted June 9, 2023 Share Posted June 9, 2023 Hi, I just had a Deye 8KW system with 2x5.1 Hubble Lith iron batteries and 14 545/550 W solar panels installed. What is the difference between the Zero export to load and the zero export to CT settings on the inverter? Quote Link to comment Share on other sites More sharing options...
GreenFields Posted June 9, 2023 Share Posted June 9, 2023 The difference between directing power to your essential loads only, versus sending it to the non-essential loads also (CT). Quote Link to comment Share on other sites More sharing options...

They didn't have to but generally they do that to limit the amount of high energy devices on the inverter. Also, it's not clear if he put any devices on non-essentials.. The inverter has that functionality by default Quote Link to comment Share on other sites More sharing options...
Sc00bs Posted June 9, 2023 Share Posted June 9, 2023 So my understanding is that: - If you have Zero export to load ticked it will not back feed any power out through the Grid-Input. - If you have zero export to CT ticked, it will back feed power up to the CT clamp and as such can power the non-essential loads if possible. mzezman 1 Quote Link to comment Share on other sites More sharing options...

This above is correct. Personal opinion, I don't think there's an absolute right or wrong way here about what the installer could/should've done. Just intuitively, the logical default for an installer should be to keep everything on essential loads, nothing wrong with that. Gut feeling is, diverting power to non-essentials could/should only be done after consulting with the owner and educating him about the options. That would be a nice touch, good service, better than to make assumptions about the client's needs, and better than just leaving him to read the manual. mzezman 1 Quote Link to comment Share on other sites More sharing options...
