Please check the blinking against the codes in the Victron toolkit (download if needed). Then update us with more details (such as which LED(S)?).

As usual manual and Victron tool kit give no sensible answers.

bulk led blinks every 4 secs in bulk phase

absorb led blinks every 4 sec in absorb phase

float led blinks every 4 sec in float phase

so seems to be operating as it should, voltages and amperages are as they should be, just seems strange that after a few days of operating as normal it now decided to blink

@Robin

Are you sure that this is not happening?

  1. The bulk LED will blink briefly every 3 seconds when the system is powered but there is insufficient power to start charging.

  2. The LED(s) might blink every 4 seconds indicating that the charger is receiving data from another device, this can be a GX device (ESS) or a VE.Smart Network link via Bluetooth

Is it not because of the following:

no. i have no Bluetooth or gx. no other add ons

just to confuse the issue . i noticed this just after i used a mk3 usb interface with telephone type plug. when accessing ve config on multiplus. Hard wired.

the mppt has been turned off since this time and still does it. as stated charging in bulk, absorption and float as should

Do you have this MK3-USB interface connected permanently (hard wired)?

@Robin

Can you clarify what you mean by this statements?

the mppt has been turned off since this time and still does it. as stated charging in bulk, absorption and float as should
the mppt has been isolated from bat and solar several times but still continues to flash

How this MPPT can be "Charging and operating as normal. Solar voltages in range of mppt" when it "has been turned off since this time" .
