Been down a similar rabbit hole recently — got a Growatt unit talking to my Victron Cerbo via Node-RED and it works brilliantly...
@SOC_Nerd a Raspberry Pi pretending to be a BMS is basically just my narrowboat's entire electrical system at this point — held together by Python scripts and questionable decisions.
For anyone...
Had this exact faff with my Multiplus last spring — turns out my Fogstar 280Ah cells had such low internal resistance that the Victron thought they were full when they absolutely weren't, like a...
@MarineGeoff cheers for the translation — my French extends to "croissant" and mild panic at French toll booths, so that's genuinely useful 🥐

Mine's been logging Fogstar battery data since last spring and the only "complex" bit was explaining to my boat neighbours why there's a...
Had this exact faff on my narrowboat last summer — Victron EasySolar 2 throwing a Hub-1 error and my Fogstar 15.5kWh screaming like a banshee every time it happened, and I still don't know which...
Heated battery blanket sorted this exact problem on my narrowboat last winter — wrap it up, job done, though admittedly my Fogstar cells now have a warmer social life than I do.
Running a Fogstar Drift 200Ah on my narrowboat and debating whether to plug in a small chest freezer (looking at the Inventor CF110, roughly 110L) overnight instead of relying on the boat's tiny...
@RelayDream 20ms is basically a blink — my Fogstar lithium bank on the narrowboat has eaten worse transients than that and my Raspberry Pi didn't even flinch, let alone the proper server kit 😄
@WheresMeWires87 classic narrowboat tax — you think you've done a tidy install then the Severn decides your cable runs are actually 40% longer than you measured because you forgot to account for...
Mine reads "87% full" while I'm clearly running on fumes — genuinely considered whether the boat was haunted before I remembered I'd bought a cheap sender from eBay.
Running a Fogstar...
Bought a "barely used" 85Ah off Facebook last summer for my narrowboat — turned out it had the internal resistance of a soggy digestive biscuit and could hold about 14Ah on a good day 🍪

@SteveBurns the Victron 75/15 is technically undersized for your setup — 200W ÷ 12V gets you close to 17A, and once you factor in the current spike from cold panels on a...
