Hello everyone,
I have created a small Node-RED flow to control the switch of the Multiplus II to avoid worrying about the "issues" of reinjection regulation:
The hysteresis function gives:
If SoC < X% then Switch to position 3 (ON mode, I prepare the inverters to require the grid)
If SoC > Y% then Switch to position 2 (Inverter only mode, no need for the grid)
My problem:
When I keep the Node-RED interface open, the flow works very well (yes, the flow is deployed), but as soon as I close the Node-RED interface, the flow no longer acts on the inverter.
I have the impression that my flow is overridden by the Victron configuration as soon as I close the interface.
The hardware setting of the system:
3 MPPTs 150-60 / 2 Multiplus 2 5KVA in parallel / Cerbo GX / Home-made 10kWh LiFePo battery (no communication with my BMS yet)
The setting of the Multiplus 2:
No virtual switch / ESS Assistant installed and configured correctly.
A small explanation to know where I am going wrong would be appreciated.
Thank you,
Best regards,
Patrick.
