@gtsquires I saw that they're indoor batteries, but plenty of people install those in unheated sheds so it seemed like a reasonable question. The 224 ...

How cold are these batteries? My first guess is that this is caused by heater discharge. FYI, the 18Kpv EPS standby consumption won't look like this...

What does your vBat graph look like?

  You are mixing AC amps and DC amps. Look at the specs again and then re-state your question. 90 amps AC @ 240VAC = 21,600 watts. 50 amps DC @...

@dtbaker61 If you have WiFi at the sites, you could place wireless temperature sensors that you can monitor remotely. This isn't a product plug, but...

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...
