Smart Solar MPPT 100/50 with VE.Bus BMS. The VE.bus BMS charge disconnect, is wired to the MPPT VE.direct port using the VE.Direct non inverting remote on/off cable.
VE.bus BMS manual says the charge disconnect output becomes free floating in case of cell over voltage or over temperature. But the MPPT manual indicates a free floating condition on the VE.direct RX pin will switch the charger on. This seems to contradict the VE.bus BMS manual.
MPPT manual reference: https://www.victronenergy.com/upload/documents/Manual_SmartSolar_MPPT_100-30__100-50/MPPT_solar_charger_manual-en.pdf section 5.2.5. RX port settings:
- Remote on/off: This is the default setting. This functionality will switch the solar charger on or off via the RX pin.
- - RX pin to GND will switch the solar charger off.
- - RX pin floating or to battery positive will switch the solar charger on.
Is the red text correct?
Appreciate any clarification.
