I don't have that issue. Can you describe your brown out?

Luxpert @Luxpower USA Team
is it configure as parallel?
Agree that the web interface and app are lacking.
For the "Home" page I'd like to see all inverters within reason (PV1,2,3 status on each), battery bank(s) status, etc.... High level stuff.
Then give me a page or two to "nerd out" on - each battery status down to the cell level (volts, amps, temps....) - off in the weeds data. Truly know what's going on.
Charts with configurable time frame monitoring every 30 seconds would work, prefer every 10 seconds-
It is pretty.

More charts and options are coming soon. It is all being worked on at the moment.

Well, I pulled the trigger and hooked up my 18KPV to the grid. (Running some test). It's currently setup like a critical load panel. I have the CTs hooked up (not sure if the CTs are required in this setup, since I'm not attempting to "upfeed" to the main panel)

Even in that case, the inverter prefers the CT’s hooked up just to monitor the bypass usage. That’s my understanding of it anyway.

install inside the inverter to the grid input wires, this will help if you don't want to export power from the inverter..

What I learned: updated 23 July
- Force Discharge (update 22 July not necessarily for my setup...may be useful for TOU)
- AC Charging (time, SOC, current)
- Limiting Force Discharge Current is neat
- I'm 90% certain that Reverse CT is flipping the CTs 180 degrees and not a left to right swap.
- No issues with voltage sag when connected to grid. (Firmware updates made grid disconnected improvements)
- Learned how to read the Smart Meter outside and verify flow direction. (Small arrow pointing right and little squares that travel right to left...)
- Peak-Shaving, I need to learn more -may not need since I'm using Force Discharge.
- Turning on StandBy allows grid to bypass inverter.
- Wondering If I need AC Charging enabled? It seems to bypass Force Discharge settings when times overlap.

That's exactly how I have it. At the moment.

the grid is acting like a big transformer..
also you can use Charge First (PV) time when you don't want to discharge your battery during the night or when there's not enough solar production.
when using other feature beside self-consumption, any time setting must not overlap with others, except charge first(pv) and AC Charge (these two features can time setting overlap).
Are you saying there is voltage sag expected if you are off grid?

when i did all the test with or without the grid the inverter work as expected and didn't notice any flicker with my led lights. any HF inverter will sag but its in the range where most electronic will work, and it recover fast.

Of course... That brings up another annoyance. Why don't the settings syncronize between the invertters? Some do, like if you kick standby it turns everything off. But like threshold settings for battery discharge do not. Also the book states that you should be in standby mode to make changes in parallel mode. This is totally unacceptable... Now you have to be in standby to take it in or out of parallel, that would make sense.

it must set correctly on the setting, to synchronize both inverter.dm with your inverter SN ot Dongle Sn and i will look into your setting. with that being said the parallel communication cable and dip switch is set and installed correctly

It happens whenver it crosses the I need/don't need battery threshold. Again I have TWO inverters in parallel. The lighs in the house all DIM then recover. By DIM I mean almost but not quite turn off. I've got a sensor samplng every 5 seconds, I could make it a bit more agressive. This happened about every ten minutes or so until the dryer was done. Glacing at the sensor data:
myhouse=> select pwm_volts,pwm_stamp,pwm_sensor,pwm_amps,pwm_frequency from power_monitor where pwm_stamp > '2023-07-08 12:00:00' and pwm_volts < 113 order by pwm_volts

Just give it a few days, these two issues are currently being addressed and there will be a firmware update very soon.

I'm sure there is a language gap, and I asked specifically about this to support. I have a single cable connected, and I believe the DIP switches are up on the primary. The manual had a continuous loop, daisy chain with the switches up on two devices. MMMV.

@GRV0423 ... And while you are at it I'd love some insight on getting a modbus call to work. I've a computer (Now an Orange Pi 5) with an 8 port RS-485 relay and 3 AC/AMP sensors monitoring my load. Based on time/current thresholds Im toggling some relays to turn off/on the EV charger. I'd like to add some of the numbers from the inverter to the mix:
