Unknown Phoenix multiplus with LifePO4 batteries

Good day


I´ve recently installed 2x 200ah topband (non bluetooth) batteries in my boat and having thought I´ve done my research throughly im having problems figuring out what this model really is. I thought it was a Multiplus with a VE.bus and it apparently is not. Then thinking it was a Phoenix Multiplus from the olden days where I could change the dipswitches and thereby program an absorption time; i find the googled manual says i should use the Push buttons...which this model does not have.

I´ve attached images to clarify.

It seems to be a Phoenix Multiplus 12/1600-70 but no manual i´ve found fits its interior buttons. Now im wondering if there is any way I can get it to effectively charge and maintain my Lifepo4 batteries.

Can someone help me out?

Multiplus compact as stated in model number CMP shows. Manual is that one https://www.victronenergy.com/upload/documents/Manual-MultiPlus-Compact-800-1200-1600-EN-NL-FR-DE-ES.pdf">https://www.victronenergy.com/upload/documents/Manual-MultiPlus-Compact-800-1200-1600-EN-NL-FR-DE-ES.pdf


If voltages from DIP-switches are not correct for your battery then you need MK3-USB programming device. Looks pretty old so might be good idea also update firmware.

Probably an mk2, not mk3 usb adapter. Hopefully you get the correct manual and can check there.

There's a section for old manuals

Good luck.
