I’m a solar newbie and old jack of all trades and master of none guy working a project of adding solar to a retired ambulance I’m converting into an RV.
I was late to the Electrodacus party having purchased most of the equipment before I came upon what is a great electronic BMS and information providing product.
I’ve been reading the forum for a month or so with time off at times to give my head time to quit spinning.
I put together a setup/wiring diagram and if anyone wants to take the time to give it a review I would greatly appreciate any advice and suggestions.Thanks, Greg
I appreciate your rapid responses.
#1, I’m a little slow sometimes and therefore I’m not 100% positive that I understood exactly what the change should be, but I made a change to the drawing of what I think you and the “Beginners” document mean. If correct, the wire to “loads” is no longer connected through the Lynx with the 100A mega fuse, or a Class-T fuse as the “Beginners” guide suggests, but the wire is connected to an 80A breaker. Is this appropriate/sufficient?
#2. Yes my MPPT is the 150/60A model and it has the external Remote H & L connections. Good catch, I missed adding those wire connections. I hope I have their wiring connection documented correctly to those H & L connectors now.
#3. I didn’t realize the DC/DC 24/12 70A converter/charger required a wire from the PVp connection. Makes sense the converter/charger would need to be shut off in the event of a low battery situation. It appears the wire will connect to the green connector. There are two screw connectors on the green connector. Based on the “Beginners” document I assume 9EXTIO+ and 9EXTIO5- would connect to the green terminal. Would you be able to explain to where the wire from PVp should connect?
#4. Had I come across your SBMS0 system earlier I would not have purchased the BMV-712, and now because I’ve had it for several months my window of time to return it has most likely expired. Since I have it, I thought I might as well install it too. If the change in #1 above is correct, it is possible it could infringe on the Lynx area where the BMV-712 shunt would be, so I might not have the necessary space to install it.
Because of space limitations, I had to break up the 2P8S battery into two 8 cell groups.
I also completed the ribbon cable wire diagram with this new version 2 document.
I really appreciate your great guidance and assistance you provide.
