I have a Cyrix-Li-Charge which I am trying to get working with a VE Bus BMS charge disconnect, and a Victron SmartSolar MPPT 75/10 solar controller. I also have an alternator I want to connect through the Cyrix-Li-Charge, but I am just trying to get the solar working first.
This is all exactly as these components are shown deployed in the example system diagram here:
That diagram was the basis on which I designed my implementation. I assumed it was all supported as depicted.
I can't get the Cyrix-li-charge to close the connection and allow the charge current to flow.
I had thought that the li charge unit just did what the BMS charge disconnect wire told it to do, but on reading the documentation more closely I see there are other conditions, such as over or under voltage. It says it won't connect if voltage is less than 13.7. Is this the cause of my problem? At the start of bulk charging, it takes a long while, definitely more than 10 minutes, to ramp up over 13.7v. But if it isn't connecting with the battery, I think it never ramps up the voltage. Correct? Seems like a potential chicken and egg catch-22.
When I contacted my Victron distributor from whom I purchased the Cyrix-li-charge for help with my installation, he told me he has never been able to get it to work and does not recommend or support them. He just sells them I guess. He says when he has asked Victron about this, they just say to use a Battery Protect in the reverse configuration (solar as "IN" and battery as "OUT"
This is a little frustrating to hear from the dealer who sold me the product that it won't work and he won't help me to get it working.
Should it work?
What support or warranty recourse do I have given that the dealer won't support it?
