2 SmartSolar parallel MPTT 150/60 + MPTT 150/85

I have 1 x SmartShunt 500A/50mA + 1 x SmartSolar 150/85 (6 Years old) + 1 x SmartSolar MPTT 150/60

I want to syncronisize all 3 Devices over Bluetooth

The new SmartSolar Device + the SmartShunt I can connect with the Menu Point "VE.Smart Networking"

The older SmartSolar has this Menue Point not. What can I do?

The Firmware of the older SmartSolar 150/85 is the newest 1.61

@Funkboje Some older Smartsolar 150-85 mppt ore not compatible with Smart Networking.

Check your model against the table Limitations in this document.

@Funkboje While nice for synchronization to work, it is not required.


It would be more important for voltage compensation to ensure that the mppt sees the actual battery voltage. Voltage drop between the mppt and battery will result in mppt's switching charge states at slightly different times.

Keep the cable between your mppt and batt short and thick to reduce voltage drop.

Keep an eye on the voltage drop, and how quickly the charge states match.
