I have a FoxEss T5 G3 solar inverter equiped with WiFi and External power meter (DTSU666). I am using the information from the DTSU received through T5 WiFi in my Home assistant. My problem is that when T5 goes to sleep mode after the sun goes out, I cannot receive the Grid consumption Power and the Load Power anymore. How can I keep the wifi and meter functions on during night hours ? I checked the parameters in the FoxEssCloud and there is an inverter parameter named Night Mode but it is already set to Disable.

I didn't think you could with the T series inverters, they normally go into standby once the startup voltage drops below 140V, and wait in a low power mode until the solar returns.

But you could try Night Mode 'Enable', if it does keep it on at night I would expect the option to be 'enabled to do it - please let us know how it goes so the answer is here for the next T series user.

Hello

I want to ask if you managed to turn on "Night Mode"?.
Because I also have a FoxESS T17 G3 with DTSU666 and I have the exact same problem, but I was on "Night Mode" and still the inverter turns off.
However, I have another problem that every night it turns off and on again 5 times until the PV really has no volts left. Maybe there is some parameter change like "Minimum Volts Start" or something similar.
