Help! Can’t charge leisure a battery

Hi, we are in a situation - have Roger’s solar panels fitted on our 6.1 Ocean and the VictronConnect controller says both leisure batteries are fine. But VW control panel thinks they are empty. It tells us to “charge now!” and nothing powered by the batteries is working (fridge, lights). On 240v hookup which we just tried, we couldn’t shift the “charge now!”. So 30 mins or so later we switched to running the engine with the “max charge” button pressed on the touchscreen, but after 45 minutes it still says “0 hours”, still goes to “battery flat, charge now” when we turn off the engine or try again on outlet power.

It is showing voltage as 12.7V but amps going up and down wildly from -18A to +32A over a few seconds, back and forth. I am a bit out of my depth and would love and advice.

How long should we run the engine for to see if the batteries take charge? Or for the control panel decides they have charge?

there a way to “reset” the control panel?

We are on holiday so need to find a fix.

(We have temporarily disconnected the solar to rule out rogue possibilities, but I am at a loss as to what else to try.) Thanks in advance!

Thanks! I have done that as per your previous post but those fuses only seems to affect the roof function? Anyway it hasn’t helped unfortunately!

If your IBS sensors have become confused by your solar setup you may be able to reset them by disconnecting and reconnecting a two pin plug on the sensor. Each leasure battery should have a sensor on its negative post.

The docs I've read suggest this could take around 4 hours for sensors to recalibrate.

The good news is that if your batteries are 12.7v at rest they are close to full.

Edit: the rear sensor is more likely to be the culprit than the front.

It worked! Disconnecting and reconnecting the read IBS sensor immediately showed full battery, 60+ hours on the panel. We have full control again and can continue our holiday worry free. THANK YOU!
Just to add you probably need to move the negative lead of your solar charge controller from the battery to the chassis ground.

Anywhere downstream of the sensor. It's well documented on here although the sensor arrangement has changed.

Yes - thank you. Figured it out. Without this forum and specifically @yosssarian we’d have been up the creek! Thanks again:)

I had exactly the same issue with errors last night after installing my solar, not reading the instructions, and connecting the cable to the negative battery post rather than directly to earth.

Anyway this morning I disconnected the IBS cable and all the errors on the camper control panel have cleared. Very grateful for the info here. :thumb
