EG4 16kPV. Just connected the dongle to China. How do I disable (preferred) or encrypt (WPA) the factory AP config? I went in via the Android app to Dongle Connect and I see the option to enable encryption but when I type in a password the set button to the right of password does not light up and it asks for some verification code which I have no idea of what that is.
Thanks!
Edit: Dongle firmware 2.06 I believe

"Verification Code Mismatch" message at bottom of the screen when I type in Signature or signature or the AP password I typed in prior.

This is what was set by SS during remote with a tech. I try not to change anything at all. 101% is supposed to keep it fully charged whilst 100% only charges it to 100% once for the day. The SS tech mentioned that even though i had EG4 Life Power 4 which means i could do closed loop, mentioned it was better to keep to open loop and set to voltage instead of SOC due to the battery high voltage i was getting.

I've PM'd. Thanks for responding.

EG4 16kPV specifications (page 1 user manual) state:
Transfer Time 20ms (default), 10 ms (configurable)
Questions:
1. How to configure the inverter for 10ms transfer time?
2. Are there any negatives/ down side to configuring for 10ms transfer time? I assume yes since that is not the default.
Thanks!

Seamless EPS switching. Enable

Appreciate the information. Is this documented anywhere? Are there any negatives/downsides to enabling Seamless EPS Switching? Thanks!
I can’t remember all downsides, but it has been discussed somewhere on the forum. I believe one was that idle consumption increases.
I personally don’t use it because It seems to cause my AC coupled inverter to kick on and off about 20 times a day.

This was previously included in the monitoring system, but I don't see it in the manual or the settings dropdown. I will forward this information to our technical writing team for adjustments.
Regarding drawbacks, there are typically none. However, fluctuations in grid voltage or frequency could lead to issues like intermittent flickering lights when this setting is enabled.

Okay but that information does not reference in any way that it changes the transfer time from default of 20 ms to 10 ms.

Inverter self consumption ?

Why? This thing can't measure its own consumption? Is it using some default value? Is this a known issue?
Inverter is charging battery, not drawing from it.
Is your CT set at negative 40 ish?

CT is set at 0 but I'm not sure how that is relevant. There is no grid voltage or current on the grid terminals.
Correct, in off-grid mode CT doesnt factor. I was curious as for when you are running from grid.
The equation for your scenario would 196 - (169 + 95) = - 68, so it is saying you are over 100% efficient. There is still 68W unaccounted for but am wondering if that is due to the fluctuations in the AC coupled solar and the 18Kpv can not calc that part in real time?
The Power values for anything under 200W, am I told by LuxP to take with a grain of salt.

Appreciate that. I missed that sentence in the documentation. Makes me wonder what else I'm missing/don't know about/not documented.

I’m have the same issues with my 18kPV and 2 indoor wall mount batteries with only AC coupling. What I found during todays testing is with closed loop coms and either charging by SoC or Voltage the inverter will do this bypass mode you are referring to, I’ll call it battery disconnect because that is what is happening as seen on the LCD. When the inverter disconnects the battery it then uses the grid to power your loads even though you have a full battery and it’s in self consumption mode. There is no reason for it to do this but I had it happen during cloudy days. This starts to happen only when the battery is fully charged, once that happens a relay clicks (not the grid contractor) and then the battery stops its charge. Now if the AC coupling power is greater than the loads, then it remains in this state and the excess is exported to the grid, but now if a cloud blocks the sun and the AC couple power is less than your loads demand, then it imports the power completely from the grid and then starts the 300 second grid reconnect timer, problem is during this countdown of the timer the inverter is only using grid power and not discharging the battery as it is suppose to. Also during this timer countdown, if the AC couple power now exceeds your loads, then it will cancel the timer and go back to exporting the excess to the grid. During this series of events the green normal LED is off, but yet the green indicator on the LCD screen is lit, they don’t agree until the battery is back connected and either charging or discharging. Please help as this doesn’t happen on totally clear days as it is either charging most of the day or discharging at night, but once the battery is fully charged this 18kPV goes crazy. EG4 please help!

Does it change anything if you disable seamless switch?
My 1st 18Kpv did this exact thing you are describing. The only way I could avoid the situation was to have the battery always charging. Either by slowing the charge rate. Or set a discharge time around the time the battery is full. So the battery is continuously charging while the sun is out. This is not ideal one reason I sent it back.

Thanks for the info, my 18kPV is currently running Firmware FAAB-1B1C with the LCD running 14/1/1/0. You should have to disable seamless switch in order for this to work properly.
Another thing you want to look at is the battery charge settings.
From the last couple sentences in your initial post, it sounds like the BMS is shutting down the battery due to over V so the inverter is disconnecting it. Can you share your settings?
