I have completely forgotten everything about setting the Victron Smart Shunt and app I fitted quite a few years ago but its readings never seem to make sense. Compared to the Schaud DT203 display in the Hymer.

For example at the moment with the solar producing 5amps the DT203 says 74% at 13.8volts which is probably about right.

But the Shunt App is saying 52% which is of course near danger level with lead acid although I believe GEL’s can go to 40%.

The Hymer display I understand shows usable % zero being roughly 50% actual.

The problem is that I am very rarely on hook-up so the batteries 3x78ah Sonneschein GEL’s never reach 100% so the shunt never, or rarely synchronises unless I am there to do it manually so presumably steadily drifts. The app is set for manual synchro and I can’t see how to set it to auto so that when I am driving and the correct parameters are reached it will automatically synchronise.

Sorry if this is a bit garbled.

Any suggestions?

OK, nobody reacted to this. Today the Victron has got so out of kilter that it is alarming thinking that the battery is too low. I have looked on the app but can’t see how to take it off manual sync so that it will auto sync when we go for a long enough drive. I know that Lenny HB knows a lot about these but can’t find our conversations from about 5 years ago on here. It is not a game changer because I have turned the alarm off. But I have an expensive piece of kit which has become totally useless and I wonder why I bothered when the Schoudt kit seems so reliable.
 
I think you can set the Victron manually to any percentage? So if the Schaudt is showing 50% and you think that agrees with the voltage then go with that.

Thanks Paddy I can’t see where to do that. The trouble is that the Schaudt I think shows relative percentage, (50% being zero) whereas the Victron shows actual. I think my problem is that the batteries never get to 100% so I can synchronise them. Especially as the mppt controller switches the fridge to battery when there is enough sun. I think I need to wait until I get home so I can re-connect the charger.

Can you post screenshot of the current settings in the connect app? The shunt should sync to 100% when the charged voltage is reached and the charge current is less than the tail current setting for the time set in "Charged detection time". The batteries will have lost some capacity in the last five years, so to give an accurate SOC the app needs to know the current capacity so it can calculate the soc. Your batteries are very good quality though. This may help https://www.victronenergy.com/media/pg/SmartShunt/en/operation.html

Thanks for this. I found that my app was out of date as was the firmware on the BMV. Updated it and the ability to set the state of charge appeared so I could set the approximate level as on the panel calculated by the Schaudt. I am now on hook up for the night so I can charge the batteries fully so the BMV can set the 100% SOC. unfortunately as I am very rarely on hook-up it has drifted way out.
 
Hopefully you won't need to synchronise it too often. Sounds like you may have it sorted
