Good Day,
I have been trying to figure out which device is limiting charging current in below setup. There is some magic 3700 watt somewhere hardcoded or configured in my setup but so far I could not yet find it.
status during scheduled charging:
Device list:
Byd 4x2.5kw B-Box device parameters
I face this 3700 magic number limit everywhere....
1. during sunny day PV max output seen as ~3700watt in MPPT 150/100 (despite panels are rated as ~5kw).
2. Multi compensates rest of the consumption from grid when energy usage (output inverted) is higher than 3700kw despite the battery is full and rated as 140A.
3. At last today I realized that when I schedule a charging in ESS setup, to fill the BYD 10kw cells in early morning, again the system transfers only ~3.7kw max to the battery .
I upgraded all components to latest version in last couple of weeks (multi to v460, ccgx v2.33, mppt v1.42, also using updated version of ESS assistant ) but nothing changed.
Battery and system is located quite cool dry environment with max temp of batteries goes up to 29C and its 230V system. Any guess?
