Charger bluesmart ip22 12/20 charges

Hi everyone

I m facing a problem with m’y charger bluesmart ip22 12/20

Well connected
Close to the 104Ah gel battery (50cm)
The battery is 15 months old and has always been connected with 250 watts solar pannels

I disconnected the solar pannels to change them so i plugged the charger and there it is

The charger gives me 14.4 V but my battery is still going low (dropping from 84%to 62% within 2 days)

I turned all the fuses off (lights,pump,…)so nothing should consume energy




Any ideas?

Thank you

Update : i reconnected the solar system and the mppt is on float,
Battery 100% straight after connection
13.78 V

Can someone explain that to me ?

Thanks again

My initial thought is that if the shunt says the state of charge is down to 68% then something is pulling power out of the battery and through the shunt.

Did you connect the IP22 at the battery or on the load side of the shunt?

Hey
I Connected direct to the battery

I read on a forum i should have Connected the electrical mass onto the shunt

Shall i do that?

Yes please, the current has to run over the shunt to be measured.

Hey
Seems to be this apparently

Thank you very much
