Which charger is in float?

Do the batteries have a BMS which connects to the Cerbo?

What settings are on the chargers?

Please give us screen shots of these and the main Cerbo screen when in float.

Bonjour, je tiens déjà à vous merci.Le chargeur rs450/100 est piloté par le cerbo. Quand je redémarre l'ensemble du système( rs450/100, multiplus2, et cerbo gx) le soir, le lendemain tous fonctionne normalement, la charge commence en vrac, après absorption et float. Mais le jour après cela recommence directement en float. Il me semble que cela est apparu peut-être de temps après la mise à jour du multiplus en version 506. Les bms seplos ne sont pas connectés au cerbo, juste protections des batteries. Le cerbo est à jour.

Suite valeur aujourd'hui. Dans le cas ou cela serait un problème logiciel est il possible d'installer la version précédente sur le multiplus.
