Posted March 19, 20231 yr Hi all, I've got my solar system installed for a week now. Specs are: 8x455w Canadian solar panels, 1x hubble lithium 6kw battery, 1x 5kw Deye inverter. System is working as expected, however the past 3 days my panels will start to generate power in the morning, supplementing the demand to my house, and charging the battery. It then suddenly stops, and drops to 10w, until the next morning. The time period when the panels produce power is sporadic. I tested by using my airfryer, the grid still supplies the demand from Eskom, and not the panels during the day, which previously the inverter pulled the power from the solar panels. No changes were made to the settings of the inverter, the zero export to CT settings were not changed and priority to grid is selected. I did a bit of research and came across thos forum, and seems like a common issue due to firmware of the inverter? Just want to know if this is the case or if something else could be possibly wrong? I did attache my demand and production graphs from the past 2 days and the realtime view of what is happening. I did contact Deye support, still awaiting feedback. Any support and feedback will be appreciated.
March 19, 20231 yr Just stating the obvious that you are activating grid-charge in every time slot whenever the battery gets to 95% SOC. Try removing that grid-charge tick box during the day when you want to run from solar. Hope it helps.
March 19, 20231 yr Author Hi Greenfields, Ok, I chaned it now. Odd that is started doing it only a few days ago. Thank you for the help. Hope it will sort out the issue. Kind Regards,
March 20, 20231 yr Author Hi all, Still the same issue. Still only generating 10w of power. The only thing that now could be an issue is the firmware.

March 20, 20231 yr Author Its currenly sunny, no clouds. I've got 8x 455 Canadian solar panels, which I'm assuming was installed in serie by my installer. It was working fine, until a few days ago, when it just suddenly stopped.

I think you need to call the installer. On a system this new it's not unreasonable to be dissatisfied and ask for some support.

March 20, 20231 yr 20 hours ago, pswanepoel1 said: Specs are: 8x455w Canadian solar panels Are they genuine brand panels? There are a ton of fake Canadian solar panels being sold all over SA. If they are the real deal panels then something is not quite right with your setup. Like @Bobster. mentions get the installer to assist or clarify.

It was working fine, until a few days ago, when it just suddenly stopped. Something changed drastically. 8x455W even on a cloudy day cannot give only 119V. There might be very low amps but not cause a low voltage As others said get the installed out before tampering for warranty purposes.
