Mes chargeurs Victron démarrent en float / my victron chargers start in float mode

Q&A and troubleshooting

Bonjour
J’ai 2 chargeurs, Victron Multiplus et Skyla, sur des Lithium avec un BMS REC.
Depuis un certain temps, même avec des batteries à 30%, les chargeurs démarrent en absorbtion, puis depuis quelques temps en float. Et ce qu’ils soient alimentés par le générateur ou par le quai.
Quelqu’un aurait il des pistes de diagnostic ?

Hello
I have 2 chargers, Victron Multiplus and Skyla, on Lithium with a REC BMS.
For some time now, even with batteries at 30%, the chargers start in absorption, then for some time in float. And this whether they are powered by the generator or by the dock.
Does anyone have any diagnostic leads?

Bonjour,
If the battery voltage is high enough, OR the chargers are incorrectly set, then they will start in float.
Also to check that the REC BMS is allowing charge to the batteries, including any charge disconnection relay.
With the Skyla, you have to remove the cover and set the ABS and FLOAT voltages with the output disconnected from the battery. There is also a dip switch to force the unit into bulk charge.
The Multi needs to be programmed with VE configure, using a Mk3 and a laptop.
