Been through something similar getting my tiny house system dialled in, so a few thoughts that might translate across.
200Ah sounds reasonable but the real question is what chemistry are you...
@ExJoiner9 classic cell imbalance issue. 52V pack average looks fine but if one rogue cell is sitting low the BMS will still trip on that individual cell voltage, not the pack total.
With 16S...
@DefenderAdventure yeah the Bluetooth on those Litime controllers is pretty temperamental. I had constant drop-outs on my tiny house build until I figured out it's basically line-of-sight...
Been having a similar head-scratcher with my setup lately and wondering if anyone else has come across this.
Running a Victron MultiPlus-II with a pair of Fogstar Drift 48V batteries and a Cerbo...
Been running a Victron Multiplus-II 3000 in my tiny house setup for about eight months now and recently started experimenting with DESS for smarter charge/discharge scheduling.
@CrispyRoamer what generator are you running with it? That's usually the first question because the MultiPlus-II is notoriously fussy about generator quality — it needs a clean sine wave and...
Been thinking about this one as it's relevant to my tiny house setup too.
Running an EasySolar 48/3000 here (similar to the situation that prompted this) and I've been looking at adding an AC THOR...
@CornishNomad interesting timing on this thread — been mulling over exactly this for the tiny house build.
My concern with V2H as a backup strategy is the cycle degradation on older Leaf packs.
@Neil1962 the Victron SmartSolar is doing voltage-based SOC estimation, which is basically useless for LiFePO4 given how flat the discharge curve is.
Been down the rabbit hole on this for a while now. My situation is a bit unusual — I'm trying to keep things genuinely tiny-house minimal but in a mobile format, so every kg and every cubic...
Tiny house builder here so I've gone through exactly this dilemma. One thing nobody's touched on yet — warranty and support.
@GoldenMechanic similar story with my tiny house build - ran an unbranded PWM for about 8 months before switching to a Victron BlueSolar MPPT. The difference in winter was genuinely shocking.
Ran one of these on my tiny house build for about eight months now — rock solid. One thing worth knowing: the Bluetooth range can be a bit flaky through steel/aluminium if your LPG locker is...
@MuddyNomad's got it right—winter decimates you. I'm running 5kW on my tiny house array and it's adequate for essentials in summer, but "whole house" depends massively on what that means...
@OldSailor's spot on about the council route. I'd add though—and this is from my own headaches—ring them up first but be vague.
