Strange Values and effect loading EV
Posted: Thu Apr 16, 2026 4:35 pm
Hi, specialists,
I'm wondering about strange values when loading my car. Here is my setup:
Inverter: H3 12.0E
Version_Master: 1.98
Version_Slave: 1.03
Version_ARM: 1.78
Batterie: EP11 BMS 1.004
Smart Meter: DSU666
Waveshare RS285 to ETH Adapter
Home Aassistant 2026.4.2 + FoxESS Modbus Integration v1.13.6
My values with car connected and Export Control = 60000kWh
My car it connectet to phase "S" only and takes 3,5kW. 2.5kW comes from the Batterie and the remainig 1kW from the grid. Because the batterie is discharged on "S" the Inverter switch also "R" and "T" to discharge.
The result is that I take 1kW from the grid while on the other hand feeding in 5kW.
So I assumed setting Export Control" = 0 will solve this - which doesnt:
So as you can see it got worse.
Also I'm wondering about "CT S" which - for my understanding should be positiv instead of negativ.
Any insights on this?
Thanks a lot.
