Stable 1200 output?

Boubsy

Hi,
Here is my conf:
Hoymiles 1200 (4xinput)
Kelly3EM (mono phase)

I tried:

1)PVHub output with 3x Splitter and connected to 3 x 400w Input of Hoymiles.
Sync of PVhub 3EM not stable.
Max output 950w

2)PVHub output with 2x Splitter followed by 2x Splitters (equivalent of a 4x splitter) and connected to 4x 400w Input of Hoymiles.
Sync of PVhub with 3EM not stable.
Max Output 60-70w

3)PVHub Output with 2x Splitter and connected to 2x 400w Input of Hoymiles.
Sync of PVHub with 3EM VERY STABLE
Max Output 800w

How do you achieve stable 1200 Ouput?

You should read Hoymiles 1600, not 1200

Try all the wires from the hub to Hoyemiles in the same length.

Tried it, not stable

Did you also tried it without Shelly? Just maximum output?

Boubsy

With 2x 3 way splitters with output set to 1200 it works. I have 1200w out
But when I activate the monitore ct to match the Shelly it becomes unstable and enable to match consumption. It stays at around 50w output

Well…. That looks like a software problem, which could be slowed with some Firmware updates.
You should write a ticket on the developer’s site.

Thas is exactly what I did:-)
Let's hope that I would have an answer soon
