Does anyone have this exact model and can check something for me please.
What is the lowest absorbsion voltage you can set in the custom battery setting?
At £999 I need to know that the item will work with my set-up.
I have selected this same item from the product demo library in Victron Connect and by going into the charger settings it will allow me to select an Absorbsion voltage of 12v.
11.5v would be better, but if it is indeed 12v it’ll work and I’ll buy it.
Hm. OK, so if you put 4 in series, with the max operating voltage of 15.5v (lead equalisation) that gives 3.875V per cell, or approx 75% soc on charge. Looks like the 15.5 could be pushed to 16v, so that would get you to 80%. That gives you a choice of 3 or 4 cells.
Hi Mike, they are sealed units from an EV. No opportunity to change to 4S.
To be honest everything works great, it’s just that for some odd reason the solar MPPT and Orion XS will allow much lower Absorbsion V than AC chargers.
The Orion XS has a minimum of 10V
The Smart Solar has a minimum of 9V
My IP22 won’t go lower than 12.8V (thus I can only use it for my chassis battery and then I charge the house battery from the chassis battery with the XS)
The Muliplus will go as low as 12V (I think) hence the original post.
I have several charge profiles. 11.5V for long term storage. 12V for daily use and 12.5V for long weekends away with no sun expected.
