Battery Voltage

Hey guys&galls,

will my system run with batteries at 56V? Even if this is is a general system-question, but would my choosen components from Victron Energy work together in this order?

I'm a newbie, coming from IT and interested alot in this subject, made my research, just checking back with a community and looking for crowd opinion and experience.

It would be a PV expansion and extension with battery; my main concern is the battery voltage; Nissan Leaf Gen I Modules /8V, connected 7Series, giving me 56V but the inverter/charger is running on 48V.

I was elaborating this with some help of the yt video of an nz-guy and a redditor who already build his battery.


Curious what you say to the total system? The idea with used car-batteries vs LifePo4 cells?


Best regards,

Max

I also am using car batteries for my ESS. I have 4 Tesla 22.2v (25.2v max) batteries in a 2S2P arrangement giving me a 44.4v system, 50.4v max. Schematic & photos on the below link if it helps.

You will be fine at 56V. If I remember correctly Victron can go up to small bit above 60V.

Thank you Louis!


As you're an expert, could you maybe answer me if the devices will work together? I did my research, I read the FAQ and know there shouldn't be general system questions, just that my dealer is on such high demand that he just sent me an offer for the components for 11k and before pulling the trigger I'd like to be sure the devices at hand work together / if there could/should be exchanged something?


Thanks for your time!


Best regards,

Max
