I have the following victron devices MultiPlus 24/3000/70-50 (Product ID 2610 with firmware 159), Blue Solar Charger MPPT 150/85 (VE.Can) with firmware v2.05 and a colour control GX with firmware v2.31. on my color control GX, i noticed when i cutt-off AC-in supply to multiplus , the battery monitor doesn't show progressive rise in percentage when there is solar charge during the day rather there is a progressive decrease in battery monitor percentile on the CCGX. Meanwhile on the CCGX, i selected connected Multiplus as the source of battery monitor. Will updating my multiplus firmware to 459 resolve this issues or is there something i'm not doing right?
