Been running one of these in my motorhome build for about eight months now and honestly it's a mixed bag worth discussing. The price-to-watt ratio is ridiculous — you simply cannot argue with it...
Really useful thread — just what I needed as I'm in the middle of planning a similar setup for my static caravan. Quick question for anyone who's done this: with the Pylontech US5000s, how many...
Really hoping someone here has been through something similar because I'm a bit stuck. Had my shepherd's hut system installed about 18 months ago by a local solar company — Cerbo GX, Multiplus,...
Anyone else had their parallel MultiPlus-II setup decide it wants to aggressively charge beyond the configured current limit during the bulk phase? Running two 48V/5000 units in parallel on the...

Had almost the exact same head-scratcher on my narrowboat last summer. Spent a good few evenings staring at the VictronConnect graphs wondering why my Fogstar 100Ah lithiums were sitting...
Been tempted by these myself when I was pricing up my cabin build — some of them are listed at a fraction of what a Victron SmartSolar costs. Did a fair bit of digging before I pulled the trigger...

@BoxerProject welcome to the forum, great first thread! 🙌 Loads of solid advice already above. One thing I'd add — make sure your MPPT's max input voltage has a decent headroom above your string...
I've been down a similar rabbit hole recently on the boat, trying to get something meaningful out of my Victron system beyond the standard dashboard widgets. The idea of creating a virtual battery...

Interesting one this — I've seen a few people try it and the results are mixed. Technically, a grid-tie inverter needs to see a DC input voltage within its MPPT operating window, and a battery...

Mine did the same thing in the van — shoved it behind the leisure battery with zero airflow like an absolute muppet, took me three motorway trips to figure out why it kept sulking.

Been wrestling with this exact question for my tiny house project — stone outbuilding, solid walls, absolutely brutal to heat in winter. Did a fair bit of research and landed on internal...

Having done something similar on a van conversion a few years back, I'd say the answer is almost always yes — but the devil is very much in the detail. The key thing people overlook is...

Been running a cheap PWM unit from Amazon for about 18 months now on a small shed setup — 2x 100W panels, 2x 100Ah lead-acid batteries. Paid about £18 for it.

Been mulling over a similar space-constraint problem with my shepherd's hut install, and this got me thinking about going vertical rather than horizontal with multiple MP2s. For anyone unfamiliar,...
@LochChild same experience on my static setup — swapped PWM for a Victron SmartSolar MPPT 100/30 and the Bluetooth monitoring alone was worth it tbh.

ExFirefighter42 replied: Worth checking your DVCC settings in VE.Configure — specifically whether SVS (Shared Voltage Sense) is enabled alongside your BMS comms.
@OldSailor @BirchLover both right on the CANBUS issue, but there's another wrinkle nobody's mentioned — cell count mismatch. Pylontech runs 15S internally (nominally 48V), same as your DIY pack,...

On my narrowboat the starter battery just... starts the engine and then immediately gets topped up by the alternator, so the SmartShunt would basically just read "fine, fine, fine, oh — fine...
@MoorSeeker had almost identical grief with my setup last winter. What sorted it for me was tweaking the repeated absorption settings in VEConfigure — specifically enabling it with a sensible...

@Jock30 with a shepherd's hut you've got such limited wall depth to play with, so every millimetre counts.
