I assumed the same thing at first, but the operation makes sense - the inverter powers itself from DC (battery) all the time, so if there is an AC gri...

@bobinforest To answer the question "where did the 30kWh of power go"... the 18Kpv consumes 1.8kWh per day in EPS standby energy (i.e. 6% of your 30...

@bobinforest I have an identical system - one 18Kpv and six LL-S batteries used as EPS standby - there is no PV. This is a battery backup system on...

Thanks, @eg4eric. Looking forward to seeing if Engineering can finally resolve this.  

The "regular" state of my 18K system is this: Normal LCD screen indicator is "On". Normal LED indicator is "Off". In this state my system is sit...

Perhaps this is a "huge security issue", but for a normal house that does not have these systems at all, with the main service disconnect for the hous...

I have an 18Kpv installed as a whole house backup (entire 200A service runs through the 18K). RSD shuts of all power to the house. This is expected si...

For calculating charging power it's better to use a nominal charging voltage of 56VDC, so charging power at 60A and 140A would be 3,360 watts and 7,84...

  You may have reached a 100% charge but did you reach a full charge? One easy way to know if you actually fully charged your battery (and thus...

  Yes, that's exactly what I do. I use a small 2,000 watt 120VAC generator through a Chargeverter. This is a manual start/stop solution and bat...

  Your batteries are all balanced, indicated by the voltages being the same, and guaranteed by the fact that you have them all tied together in...

Here is a video that does a pretty good job explaining the "SOC drift" that you are experiencing. It's a very common behavior - my system does this to...

@eg4eric OK, thank you for the clarification.
