BYD B-BoxPro, BlueSolar 150/85VE.CAN, and SmartSolar150/85

Good day,

We have an existing system with 3 MultiPlus 48/5000/70 (in parallel), 4 BlueSolar 150/85 VE.CAN, 2-BYD B-Box Pro 10 kWh, 1-BYD B-Box Pro 7.5kWh, and a Color Control GX.

One of the 4 BlueSolar had a 0 current reading, so we requested for a replacement. Since, BlueSolars are not anymore available in the market, they sent us a SmartSolar 150/85 as a replacement unit.

1.) How can we synchronize the SmartSolar to the existing 3 BlueSolars and what will be its connection to the CCGX? What are the needed accessories and upgrade to sync the charge controllers if it is possible?

2.) Can the BYD BMS communicate with the BlueSolar 150/85 VE.CAN?


Thank you.

Hi @Harry Chavez,

Interesting timing on this one @Jan Brix Castillo - in his post is in the equal, but opposite situation that you are in.

Would you both be interested in a trade?

Harry needs Jan's (now discontinued) older model VE.Can MPPT,

Jan needs Harrys replacement Smart Solar 150/85 which is not easily compatible with his current system.

If you are both willing to swap MPPTs, then this would be the EASIEST solution for you both.

If you are both unwilling, or unable to do this swap trade, then I will write up longer solutions for you both, but they will not be as cheap or as easy.

Thanks for the quick response @Guy Stewart.

@Jan Brix and I are colleagues.
We have crossed out the idea of trading/swapping the units as we thought that the BlueSolar from the system that I was talking about was ruled out as defective, since it shows 0 current reading.

Also, In Jan's case he needs 2 SmartSolar since he has 2 BlueSolar.

We would like to know the solutions so we could correct the systems and it can work properly.

Thank you.

Do you have a wiring diagram of the system, specifically how the comms cables are currently connected between GX, MPPT and Battery?

Currently, the MPPTs are daisy chained and connected to the GX VE.CAN port also the BMU of the BYD is connected to the VE.CAN port.

GX only displays the Battery.

We just found out lately that BMU and MPPT should be on a different CAN Port and CCGX has only 1 VE.CAN port the the port is for RJ45 terminator.

Hello Harry,

for some reason I received a reply for your post. I’m writing to let you know that you may be missing a response.

Strange thing is I have a smart solar mppt 100/30 that just became available because I had to upgrade to a 100/50. I increased the size of my solar array which exceeded the 440W and 30A ratings. It’s about 6 months old
