Dear Community,
For my campervan I am creating a system of the following products and I have some questions about them, hopefully somebody can help me.
I am going to use the following setup in my t4 California Westfalia from 1991:
- 130wp solar panel (and maybe a second one)
- SmartSolar MPPT 75/15
- BMV 712
- Phoenix 12/1200
- 200 ah Lithium battery (not from victron)
I want to use all Victron products in the victron app if possible.
The first question is, can I connect the Phoenix 12/1200 via VE.Direct to the MPPT or the BMV so that I can use it in the app or do I need the bluetooth dongle? I found the dongle rather expensive for what it can do.
Second question, I maybe want to use an battery temperature sensor that works together with my MPPT, is the only possibility the Smart Battery Sense? Or can I also use the battery sensor from the bluetooth dongle? Or the Battery sensor that can be bought for the BMV? And what is the difference between them?
Third question, do the lithium batteries of victron have a power shut off on a certain temperature that is to low or to high? I read some batteries from other brands do shut of at -7 or something. And what is the benefit from an external battery management system that Victron recommends and sell on top of the internal BMS?
Fourth question, would it be recommended to switch my current lithium charger for one from victron? Or is that useless?
Kind regards,
