Reduction in power of solar chargers

Hello,

I just noticed that all my chargers, MPPT and RS, have a power decrease
cyclically on each device, but they don’t synchronize with each other. I don’t know how long this has been happening.

I think I’ve tried everything to resolve this problem.
I’ve turned off all the chargers one after the other, disconnected EVCS, the Lynx shunt, etc.

Restarted the Cerbo, the VE-bus, disabled DVCC, and updated the multis.

I can’t find the reason. You can see the problem in the various photos… Help!
The photos are from Home Assistant; it’s also visible with Victron Connect, but not on VRM.

I’m in ESS mode with two MultiPlus chargers in parallel: one Cerbo, two MPPTs, and one RS solar charger, one EVCS, and one Lynx Shunt.

Thierry

Un MPPT qui cherche régulièrement s’il est bien au point de fonctionnement optimal?

Ok, if that’s correct, I’d like to know if everything is normal… For the MPPT, it’s every ten minutes, yes. But for the RS, it’s every 2 or 3 minutes

peut etre que lla recherche d’ombrage avancé est activé dans les parametre du mppt onglet solaire

Indeed, this was enabled on the RS, but what about the MPPT 250/60 and 250/80? Because there’s no solar parameter. Is their operation normal?
Thanks.

cette option n’est pas disponible sur le mppt blue et smart
mais dans tous les cas pas de probleme, c’est normal.
