Hi All,
I am wondering that ESS feature does not properly respect the deactivated "Grid feed-in" option.
In following screenshots you can see that the grid power flow deviates roughly between -2.000W and +2.000W, although it is not expected to feed-in anything.
Since I am not allowed to feed into the grid, I am forced to move away from ESS to actually deprecated HUB-2 application.
I would highly appreciate, if Victron could consider
- a HUB-2 equivalent feature in ESS solution again and
- assure that relevant energy is used mainly from battery and not from grid
Examples
- grid power changing from +1.447W to -1.756W
- grid power changing from +2.006W to -1.709W
Configurations
Both configuration options aren't successful.
My environment
- 3xMultiPlus-II 48/5000/70-50 in 3-phase (firmware 477) with a
- ESS zero feed-in configuration
- Multiphase regulation on single phase
- Grid setpoint defined at 80W
- ESS zero feed-in configuration
- Fronius Symo 6.0-3-M (firmware 3.16.7-1) – connected to AC-OUT1 (critical loads) – no additional smart meter - sunspec activated
- Victron MPPT VE.can 250/100 rev2 (firmware 3.02)
- PV modules all with absolutely identical direction and no shadowing
11kWp in total: 6kWp on Fronius and 5kWp on MPPT - BYD LV 15.4 (allowed charging and discharging current during the test procedure 243A) - BMS connected via CAN-bus (firmware 1.16)
- VenusGX (firmware 2.60) - currently 2.62-beta5
- Any component with latest firmware as of today
