@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...

@ouijifour your reply is completely off-topic for this thread. The issue is faulty charge control by the 12000xp when running "open loop" with user de...

ping. @eg4eric , any word on target date for release of an update to address the "no float" bug with the 12000xp open loop charging?

I finally got a reply today from Support acknowledging this problem, and confirmation that "they are working on it".... but no target for release of a...

the silence from EG4 is deafening.

it looks like ceaa-508 introduced a bug, and did NOT include a fix for open-loop lithium charge control. What will be in 509 ? When ? ...I really ne...

I got a contact from EG4....but there is no fix yet. I still see voltage stuck at end of charge rather than relaxing to float once charge is complete.

A hibernate mode might be interesting for cases that want to minimize AC out to Loads. However, if you have turned off your refrigerator and all hea...

one important consideration is that all the input on each MPPT should be at or nearly at the same string voltage.   for example, you would no...
