The Problem:
- When AC loads => 2300W than BYD doesn't charge.
- When AC loads = 1900W than BYD charges approximately with 300W.
- When AC loads = 600W than BYD charges approximately with 1600W.
Also:
- When change "optimized without BatteryLife" to "Keep batteries charged" there is current flow from battery to loads. And batteries don't charge.
- Time to time I see "Recharge" as state of charge (but actually it is Bulk state).
What we have in system:
- Quattro 48/5000/70-2x100 - 1pc (last firmware).
- Venus GX - 1pc (last firmware).
- BYD B-Box battery - 2.5kWh.
Additional was done:
- We've turned off all loads with motors, inductive and capacitive.
- Ambient temperature was in ranges: 23*C ... 30*C.
- Quattro Input current limit = 25A
- BYD Charge current limit = 35A
- BYD Discharge current limit = 35A
- ESS assistance - last update.
- Also was installed previous firware for Venus GX, after - last version.
- Was reinstalled firmware for Quattro.
- BYD logs were read (all is fine with that).
