Hello Victron community,
I’m putting together a system for a motorhome and I have three (3) questions
-
First one is concerning the current rating of the Lynx BMS :
I have a 12V Victron Smart battery 330AH and might be adding another one in parallel down the road. I’m planning to use a Multiplus 12/1600/70 as an inverter/charger.
What value should I look for when deciding between a Lynx BMS 500 or 1000 ? Is it just the power draw of the inverter ? (And that would mean I must not exceed 6kw as stated in the doc of the BMS).
Or should I also consider the max discharge value of the battery which is 400A (800A with two 330AH in parallel) ? What if I have a 12V AirCo pulling 1000W ? What if I bump up to a 12/3000 inverter ? This is not clear for me as you can see. -
Second one is the fusing of these 330AH :
I might be wrong but is the ICC of a single 330AH exceeding any mega fuse ICC rating ? What would you recommend in the single and parallel config ? The single can accommodate a ANL fuse as the fuse casing is external, but what about the parallel setup with the fuses in the Lynx Distributor ? Do I already need to go with the Class-T Power-In ? -
And last one is the Battery Protect :
What is the use case of the Battery Protect on the 12V loads line, That looks redundant to me looking at the BMS features, but I’m sure I’m missing something.
Here’s some diagrams to illustrate my setup :
With one battery :
With Two 330ah in parallel :
Thank you very much to anyone taking a look at this, I stay here to answer anything if I wasn’t clear.
Cheers !
