Good points from @Trigger and @BordersExplorer already. One thing worth adding: the 50A rating is the output current, not input.

@RustySkipper same narrowboat setup here, been through this twice now. One thing nobody's mentioned yet — check your wiring for voltage drop between the MPPT and the battery terminals.
Great question @Lefty28, and the others have covered the basics well. One thing worth adding from my own experience running a BougeRV 30L off a Victron SmartShunt + 200Ah Fogstar setup — your...

@HeatherGazer fellow shepherd's hut person here 👋 — what BMS did you end up going with? Genuine question for the thread actually: has anyone successfully tested one of these mystery batteries with...
@RetiredNurse49 that three-day rabbit hole sounds painfully familiar — I've been there with my boat setup too, just with different kit. What I'd add, having run a similar arrangement in my garden...

@Cleggy is right that the specs matter, but there's another factor worth flagging: chest freezers are notoriously inconsistent in their actual consumption vs.

@KentCruiser what wattage per panel? That's the critical bit before anyone gets too excited. 40 panels at 250W is a very different proposition to 40 at 400W+. Also — SMA Sunny Boys being grid-tie...
Floating neutral on a boat hull = a bad day waiting to happen, trust me on that one — bond your neutral to earth once at the inverter, nowhere else, or you'll be chasing phantom faults till the...

Interesting thread — has anyone narrowed down whether this is a Venus OS firmware version dependency?
Had almost exactly this with mine last spring. The thing that finally cracked it for me was checking the VRM portal's "Last seen" timestamp rather than just the connection status...
Really useful thread this. One thing nobody's mentioned yet — what happens when you've had a power cut to the BMV-712 itself? I've found on my shepherd's hut setup that if the BMV loses power even...

@Boycie25 that last bit made me chuckle — story of my life with Victron updates honestly. What I will say is that on a narrowboat, squinting at the old layout on a phone whilst standing in a...

@Lefty28 worth checking what ambient temperature you'll be running it in — a freezer in a hot van in summer will cycle far more frequently than one sat in a cool cabin or boat.

Good shout from everyone here. Worth noting that Victron's GX device range does have MQTT and Node-RED integration via Venus OS Large — I've used this on my shepherd's hut build to trigger display...
@Macca64 oh this rings SO many bells — had almost the same thing on my narrowboat last spring with a Multiplus II 48/5000.
@LesWood78 got there before me on the VA point, so I'll spare everyone the repetition. What I will say is that this bit me properly when I was building out my van setup.
@FormerMariner36 this is ringing massive bells for me — had almost identical behaviour on my narrowboat last winter with a 100/50.
Parallel them with proper busbars and let the MPPT see one combined bank — trying to charge two isolated LiFePO4 packs from a single MPPT is a recipe for one battery doing all the heavy lifting...

@ZFS_OffGrid seconded on the battery — not worth it full stop. Been running a small setup in my shepherd's hut for a couple of years now.
Spent three weeks wrestling with this exact setup in my motorhome before realising I'd forgotten to enable PowerControl in VEConfigure — felt like a right numpty, I can tell you. Also worth...
