sounds like a real load.... 6-7kw would definitely show a little corresponding voltage sag. The heater in the wallmount (280ah) battery is a few hundr...

@jxnhrpr if you are paralleling from existing..... I *think* the "master" settings are all copied over to the slave... but maybe not the underlying fi...

@jxnhrpr if you are bringing the inverter back to a shop to update.... why not hook up to AC-in ?  

unfortunately, firmware updates require wifiI am totally with you.... especially for off-grid inverters like the XP series. I do have a number of off-...

why do you shut down when you leave? Why not leave it up so PV can maintain batteries ? how completely do you shut down ? i.e. batteries "off" to mi...

@yooperjay mmmmmm, this is not generator transfer related in this case either as there isn't one hooked up. This blink occurs when charging by regular...

@yooperjay Nope, your setup is not similar.... you have AC in, and my client is off-grid (NO ACin).   The problem she is reporting cannot hav...

@eg4eric News on fix for charging open loop by voltage ? I'd be happy to test. seems like developers should be able to spot the coding difference betw...

@ouijifour most mfg BMS don't start balancing until 56.0 or thereabouts as the current drops during the CV phase of charging. An end of charge voltage...

@ouijifour the time it takes for voltage to rise from 54 to 58 (during the CV portion of charging) is typically plenty for internal top balancing for ...

@eg4eric I find it interesting that the 6000xp apparently has SOME internal temp sensor for ambient, but the 12000xp does not. I do have some temp sen...

@ouijifour As I noted.... this bug does appear to be fixed for the 6000xp.... but not for the 12000xp yet. There is no need for the average user to ...

The 6000xp firmware ccaa-191011 seems to have fixed the bug with open-loop charge control for LFP... mostly. The resulting charge curve is "correct" m...
