i want to control a EasySolar-II 48/3000/35-32 MPPT 250/70 GX over modbus, i have read about the ESS modes. I want to use Ess mode 2 or 3. but i do not know how i can set those modes.
I am able to read and write all data though modbus. i just dont know how i can see in what ESS mode the device is.
How do i set the ESS mode on the device ? perhaps via remote console, modbus or VE-configure ?
Thanks in advance,
R
Hi @rensW,
Changing the mode setting is described in the ESS Mode 2 and 3 manual, in section 3.3.
On the GX device, Settings→ESS→Mode to external control.
How can mode 2 be set? It is not possible from the GUI? The dbus setting "Settings/CGwacs/Hub4Mode" is always 1 on the first three settings and 3 on the last (External Control).
What is actually the difference between these two modes? Is the only difference that Settings/CGwacs/MaxChargePercentage is honored?
Did you figure this out?
Posting via MQTT to Hub4Mode set it to '2' correctly.
The AcPowerSetPoint now is no longer valid for all 3 phases and needs apparently to be set for each multi separately, compared to Mode 1, which would try to implement the setpoint on the meter.
