Hi,

It works well with the Deye, I have a string of 8 panels connected to MPPT. On cloudy days with sunny spells, I sometimes have current peaks at 16.7A and that doesn't seem to pose any problems.

That said MPPT Deye are not perfect, especially when there is shadow on the panels, see the subject below. I noticed the same problem at home. This may be resolved with new firmware.

Another criticism, Deye 6K has a large self consumption of 70~80W. This consumption is lower in battery-free mode.

That said, it is a very good hybrid inverter.

Curious MPPT behavior

Dear Powerforum community members. I recently installed a Deye 8kW inverter with 10 x JA 540W panels and a couple of batteries. Panels are two strings of 5 each facing the same direction and having the same slope. Works like a charm except a curiosity that I picked up. In the morning one string i...

Thank you, i saw the picture with the new menù with multi point scan but never immagined that doesn't work...
I have some shadow in morning but on all the panels so maybe this kind of shadow doesnt trigger the problem.

Self consumption is from grid?
I made some search on consumption and an installer told me 30-40 watt and that if is higher its because there is floating enabled in battery settings

I don't see any relationship with floating.
Off-grid it can be 80W consumed from the battery.
On-grid it is 40W from the battery and 40W from GRID.

There is a Low Power mode (only for on-grid) and a Shutdown mode only for off-grid with lower consumption but with the inverter output OFF.
