It is available via Victron Professional. You can register there for free and download it.

Alternatively, I put it in a ZIP file, attached to this post.

looking for that program I found:

THIS PAGE IS DEPRECATED: Use VictronConnect instead of mpptprefs

We recommend to use VictronConnect instead of mpptprefs. Much simpler and faster to use. Also it includes automatic firmware updates.

********************************************************************************

I use some hand crafted code running with my BMS system to dynamically limit the charge current from the Blue Solar charge controller. With lithium batteries this is required - or you need a disconnect relay in the PV side of the MPPT. Thus when a cell achieves maximum charge, the charge current is reduced. Trying to do this with a voltage set point won't work well, as a single cell will reach maximum voltage first. Calculating the maximum pack voltage by n X max cell voltage can lead to an over voltage situation.

Je sais cela mais pour l instant je n ai que un bluesolar 70/15 non peis en charge par victron connect je vais augmenter mes panneau pour mes lifepo4 elle ne sont pas communicante je voudrais juste limiter la tension de charge a 13.9 et le floating a 13.2 vivant sur mon bateau je peu couper mes pv quand je suis a 100% ou avant sur les nouveau mppt on peut couper l absorption lorsque le courant absobez diminue a 2 A je pense que ca peut remplacer le relais votre solution est bien mieux mais avec des baterries sceller MOIns facile a moins de les ouvrir le bms a une interface de communication can merci de vos renseignement avez vous un gitub pour votre bms bonne soiree
