Smart BMS 12/200 Questions (the NEW one not the standard BMS 12/200)

My Equipment so far..

Cerbo GX

SmartShunt 500

Smart BMS 12/200

Smart Lithium 100

Smart IP65 Charger 10A

Some questions I have

1. Where should a Smart MPPT 75/10 be connected to charge the lithium battery with the correct voltage.

System+ has a voltage drop of about 0,2 V compared to the lithuim +

2. How does the MPPT stop charging when the VE.direct port is connected to the Cerbo.

3. Where is the Smart IP65 charger connected to charge with the correct voltage and how does it stop charging.

Thanks,


Peter

Wenn ich das richtig verstehe, kannst du den Solarregler als auch das Ladegerät an System+ anschließen. Das BMS trennt dann intern die Verbindung, wenn die Batterie voll ist.

Alternativ kannst du beide Ladegeräte auch direkt an der Batterie anklemmen.

Dann musst du aber für den Solarregler das Zusatzkabel kaufen, mit welchem der Regler über den Charge disconnect Ausgang des BMS kontrolliert wird.

Ob der IP65 Charger einen entsprechenden Eingang hat, weiß ich nicht.

You'd better connect both directly to the battery and use for both separate BatteryProtects controlled respectively by "allow to charge" and "allow to discharge" outputs of the BMS. Mind the 10mV source current limit of the BMS. One BatteryProtect consumes 1,5mA.
