Inverter not charging when on grid/generator

So i recently upgraded from Tubular batteries to Lithium ion. I noticed after installing the lithium batteries, my inverter down not charge when ever am on grid or generator. only charges via solar. what could be wrong? i have updated all the firmware.

You must update the configuration after a firmware update.

A firmware update sets the battery charge voltsge to 12V for a 12V system. It is all detailed in the firmware update documentation how you save the settings, update the firmware then reload the settings.

this is the current status.

my inverter is a 48V system, how does the firmware update or upgrade to lithium affect this?

See below my current setting as downloaded.





I can not see any issues with the settings.

The only one I do not know about is the grid code other, is this what you had before the upgrade. Are you feeding back into the grid or just consuming from the grid. Some firmware updates have grid code changes.

@stephenstiga After the first reply, I recalled something else, the V556 version of the firmware improved charging and was meant to reduce the need for the weak ac setting. Remove the tick from the weak ac setting in the charger page and try again. That setting does not affect the MPPT charger.

Another question, do you have Victron batteries with a VE Bus BMS, if you do then tick the configured for VE Bus BMS box. That setting does not affect the MPPT charger.

@pwfarnwell, i dont not feed into the grid. I only consume from grid/generator. Also, in my country (Nigeria) we do not have applicable grid codes

OK, I will remove the tick from the weak ac setting in the charger page.
I do not have Victron lithium battery but battery is compatible on JK-BMS

I have an update for my Color Control GX but unable to update


You might have an earlier firmware stored as a backup on your device. V3.60 has been causing some problems with CCGX. Go into settings, general, firmware, stored back up firmware or try the update from the CCGX rather than through VRM.

i dont see any grid imput current.

I just tried from Local and it still showed error during installation of V3.55 on color control

On the Charger page remove the tick from weak ac input.

No idea about the firmware problem, several recent issues are covered on here re the CCGX or start a new question.
