A while back, I bought a BlueSolar 100/50 with the old style VE.Direct Bluetooth dongle (ASS030536010.) All new and boxed.
I have now decided to upgrade my system with much more stuff...
- a new SmartSolar 100/50 to swap for the BlueSolar 100/50 + VE.Direct Bluetooth dongle
- a second SmartSolar 100/50
- Winston LiFePo4 700Ah battery bank
- MultiPlus 12/3000/120-50
- REC Active BMS though VE.CAN interface
- CCGX acting as the SOC% meter with DVCC from REC and interfaced to MultiPlus VE.Bus
- USB Bluetooth dongle for CCGX
My questions are:
1. I have read on this forum, that I can expect the REC ABMS to monitor the LFP battery bank, and transmit SOC% via VE.Can to MultiPlus and SmartSolar which will stop charging at my defined limits.
2. Should I buy 2x SmartSolar 100/50 and sell the BlueSolar on eBay? I think I need the VE.Direct to interface to CCGX, rather than connecting a Bluetooth dongle. And I very much want to connect to both controllers via Bluetooth with the Victon Connect app. (The VRM looks very nice, but I prefer seeing the info direct on a native App without all the WiFi browser stuff.)
3. In other words, am I right that the CCGX does not transmit over bluetooth the information it receives on VE.Direct from the SmartSolar / BlueSolar - as a native device for viewing and configuring on VictronConnect?
4. But the CCGX does receive full data and configuration from the MultiPlus's VE.Bus and shows this on Bluetooth? Or do I need to buy the Smart Bluetooth dongle to achieve that?
5. I don't plan to buy BMV-712, as the REC BMS sends SOC% data direct to CCGX using DVCC. Will this be visible on Bluetooth somehow from a Victron device? I think I am correct in thinking that the REC BMS is more likely to get an accurate count of SOC% than BMV712, as it is counting Amps / Coulombs and resetting SOC% according to cell voltage heuristic. (If that sentence makes sense!)
5. I don't think I need Ve.Bus USB MK3 adaptor (ASS030140000) as I can use the web browser interface to CCGX to make initial configuration / download & upload settings and firmware. Or should I buy one just to get things setup?
6. How do I get the CCGX on Bluetooth - is this internal, or should I buy a USB bluetooth dongle. I have seen models recommended in the documentation. Is this the best way to do it for a decent range i.e. 10m? I think I read in the Venus online manual that the range was very disappointing.
7. Am I going about this the wrong way? Is Bluetooth configuration / monitoring reliable enough (on a 14m sailing yacht) to be the fundamental connection monitoring method? I am currently viewing the CCGX as an auxilliary display - I don't plan to 'go downstairs' to touch the buttons very much, as I would rather sit in the cockpit to view the status of the system (on my waterproof Sony Tablet!) Am I dreaming the wrong dream?
Thanks for your suggestions. Andy
