Differnce between two MPPT 250/100

I need upgrade EasySolar-II 5000 with second MPPT. I see in shop 2 MPPT 250/100. One is SCC125110412 and other SCC125110441. What is the difference between these two models.

As I understand it, you need to use VE.Direct and remote wire in parallel to connect to the existing one.

Thanks.

One is the BlueSolar and one is the SmartSolar. The SmartSolar has built-in Bluetooth.

We only use the SmartSolar in our operation, because the Bluetooth is helpful for troubleshooting and commissioning.

Thanks, got it!

Am I thinking about the connection correctly? VE.Can is not used.

Bluetooth is for configuration / troubleshooting, not for operational communication with the system that includes a GX device.


In the case of a system with a GX device, you can use either VE.Direct or VE.Can.


VE.Can has the advantage of being able to connect many units on a single bus ie. one (GX) to many (MPPTs) wheres each VE.Direct port can only be used for one MPPT (one to one).

I think in EasySolar-II 5000 VE.Can is only for BMS. it is correct to use VE.Direct-USB and MPPT remote switch port wire in parallel to the existing one MPPT?
