@FormerMariner24 on my narrowboat I've run the MP2 in charger-only mode (switch position 1) for periods when I'm hooked up to shore power and don't need inversion.
Had this exact situation on my narrowboat last winter — BMV-712 reading 67% whilst the BMS was showing 54%.
@RustySkipper narrowboat here too — had this exact headache when I first fitted my 200Ah Fogstar bank.
One thing worth checking that nobody's mentioned: make sure your BMV-712 has the correct...
Bit of an odd one for me to weigh in on given I'm on a narrowboat in Yorkshire and you're talking Fresno, California — fairly different contexts!
That said, a dual Quattro 10k setup is serious kit...
Been seeing these Vatrer packs pop up on a few threads lately and I'm genuinely curious whether anyone's had long-term experience with them.
Running a narrowboat over winter and trying to work out if my setup is going to be viable without running the engine every couple of days just to top things up.
Currently got a single 100Ah AGM...
@TracyAllen nailed it on the sun angle — I ran the numbers on my narrowboat setup last December and was genuinely shocked.
@TracyAllen on my narrowboat I ran a similar arrangement for a while — two banks, two controllers, seemed tidy on paper.
Main thing I'd add that hasn't been covered: if you're ever tempted to...
@BirchTrevor had almost identical behaviour on my boat last winter — Fogstar Drift 200Ah with a Multiplus 12/3000.
Worth checking whether your BMS is sending a DVCC signal via VE.Bus or if it's...
Good point from @ExPostie there. One thing worth adding — the load output on the 100/20 is also temperature-limited in practice.
Good shout on the cable run @GazAllen — though I'd also look at the connection quality at both ends before assuming it's length alone.
On my narrowboat I had cycling behaviour that turned out to...
Bit of an odd one this, and curious whether others running Pylontech with a Multiplus-II have seen similar.
On my narrowboat I've got a Multiplus-II 48/3000 paired with 4x Pylontech US3000C...
Done this on my narrowboat for the past two winters so can offer some real-world numbers.
A decent small chest freezer (I run a Sealey 35L) averages around 25-40W depending on ambient temp.
Worth checking your ESS assistant configuration specifically — if you're AC-coupled and running ESS, the frequency shifting behaviour can cause the Multiplus to oscillate when the BMS is...
Good points from both above, and @DownsCruiser is right that capacity alone doesn't tell the whole story.
Worth adding: depth of discharge matters enormously here.
