Is this regardless of essential / non-essential? ie. Will it blend all 3 if it's on inverter AC output (essential) or back-fed via AC input (non-essential)?

Still looking? @Muchachos I have 2x US3000B Alternatively, if anyone is selling 2x US3000B, I would expand my system to 4

@Coulomb Thanks, and thank you for your insights to my problem. I'll start investigating what's causing the massive bill increase. I should probably start by getting a proper power meter in the DB lol Not sure if I need to close this thread?

Thanks, I've gone ahead a purchased a Watt meter which goes to 16A for R340. Image attached. The power factor hovers around 0.24 with idle load and drops to around 0.16 with no load. So working with this, the inverter constantly draws around 60W-90W when my loads are idle (~20W). Do these meters and the electrical meter used by the utility company all just measure phase angle with (I would guess) some zero-crossing detection to get the Power Factor and then multiply that with the apparent power (VA = V RMS and A RMS)? Or would there be some more sophisticated way?

@Coulomb I realise perhaps I have been wrong assuming PF = 0.7. How would you recommend measuring the real / active power in this case? I have access to a basic DMM and an entry level Keysight scope. I'd like to confirm the reactive power is as large as you suspect it is. Appreciate the assistance, thank you.

@BritishRacingGreen I have a CT Coil with 7-seg digits displaying the current draw, frequency and voltage of my mains placed in my DB box. The inverter backup UPS is the only thing I've changed and my bill has gone up significantly. Images below show the measurement with the 100% battery inverter connect and disconnected. Minimal load on the inverter. Edit: It may be worth mentioning that my area fortunately does not get loadshedding but I cycle the batteries every 4 days.

I have noticed over the past few months that my electricity bill has gone up significantly since setting up my Kodak Inverter + Pylontech US3000B (x2) setup (no solar). There seems to be a constant 2.6A draw on my mains when the inverter is running (batteries 100% for a long time and no load ~20W). When I disconnect the inverter's AC input from the grid, the current draw is 0.0A on my DB mains - so it isn't something else (like geyser, oven, etc.) drawing this current. Mains have my whole house connected, inverter is used as a UPS for my office setup. Does anyone know about this current draw issue? The constant 400W draw surely can't be normal. This is when everything in my office is off / standby - 20W confirmed by looking at the load on the inverter. Input is around 233V-235V 50Hz, output is 230V 50Hz. I am hoping it is just a configuration that someone can help me out with. Watch Power application Screenshots of configuration attached.
