hi All,
The moment I add an AC Coupled inverter to the output of a Quattro the ESS doesn't work as desired. It doesn't cycle the batteries at all.
We have enabled frequency shifting and measure the output of the grid tie inverter via a AC current sensor.
There is a grid meter in the setup and comms is OK
I'm on the latest firmware 469, all other devices on the latest firmware as well.
This problem is only with Quattro range of inverters and not the multiplus Inverters.
The Quattro inverter keeps on showing "Bulk" or "Absorb" mode and doesn't discharge the batteries at all. it will use only Grid at night.
ESS Relay test was successfull.
ESS setup is correct.
Parameters from lithium batteries are OK.
