Not 100% sue that anything is wrong as such.. but haven noticed since turning my engel fridge off from mains (as its main priority and on an inverted socket) so it is on DC only, that the charge voltage is fairly unsteady in 'float' mode.
Set up is 326ah CALB celled (2p4s) battery - Daly Smart BMS - 250a Raspberry pi 3b+ running Venus OS 2.70~15 - BMV700 connected via victron VE Direct to USB cable, then the multiplus.
Set up is on shore power bulk to 14.2, absorption for as short as possible,. float at 13.5. DVCC Shared Voltage sense is ON
The thing I have noticed is that when the fridge kicks in, the voltage drops eventually 0.1v (over a few minutes) to 13.4v, the multiplus then wakes up and starts adding current, eventually overshooting 13.5v to 13.65, then dropping down slowly again.. and the process continues.
Prior to having the fridge on DC i had a steady draw of about 2.4amps, it took a while to settle but the charge voltage eventually settled at 13.5 and held...
I'm assuming that this is maybe by design... i just dont like the overshoot too much, am I missing a setting somewhere that tells the MP when to kick in (ie 0.1v below and stop 0.1v above?)
