Multi HS19 Solar 15k
Interesting one. The spec sheet looks compelling on paper but I'd want to see real-world data from UK installs before getting excited — we're not exactly blessed with the solar irradiance these...

Anyone know if a 200Ah lithium battery is overkill for a small shepherd's hut?
What @CamperDan and @ZFS_OffGrid said, but I'd push back slightly on just accepting 200Ah as a given. The real question is your solar input.

Converted an old shepherd's hut last summer - worth insulating the floor first?
@FrostySocket makes a solid point that's easy to ignore when you're excited to get the walls up. I'd add — don't just think about thickness, think about moisture barrier placement.

VE.Bus Error 11, Step 0
@MuddyNomad VE.Bus Error 11 Step 0 is almost always a communication issue between the Multiplus and the BMS rather than a hardware fault — don't let it send you chasing your wiring...

Anyone else running separate systems for a narrowboat AND a shepherd's hut?
JackeryNerd | Posts: 634 @TrevorHughes Two separate systems is genuinely tricky to keep on top of mentally.

Anyone else had their JK BMS throw a low temp charge fault in winter even with heating pads fitted?
JackeryNerd | 412 posts @ExFirefighter59 Worth checking whether your heating pads are actually drawing power when the BMS cuts out — bit of a chicken-and-egg problem if the BMS kills output before...

Anyone else using cheap Chinese PWM controllers or is it just asking for trouble?
@Ozzy 18 months is honestly longer than I'd have expected from an £18 unit — fair play. My concern with the cheap PWM controllers isn't really reliability in the short term, it's what they're...

Multiplus shuts down when VE bus is connected to cerbo ga
@TorJake another truncated post, brilliant 😄 Since everyone's already speculating — I'll add a different angle nobody's mentioned yet.

Victron MPPT keeps dropping to float way too early — anyone else had this?
Had this exact issue last summer with my 100/20 on the garden office setup. Drove me absolutely mental for weeks. Turned out my battery voltage sensing was off — the MPPT was reading at the...

Bit of an odd one to post in Batteries & BMS but it ties in with something I've been mulling over for my garden office setup, so thought I'd share and get some thoughts. A mate of mine picked...

Anyone else using a Raspberry Pi to log their inverter data locally?
Been doing this for about 18 months now with my garden office setup. Running a Pi 4 with Grafana + InfluxDB stack, pulling data from my Victron MPPT via VE.Direct USB cable.

Anyone else running a 200W solar setup in their van? Battery drains overnight
@FormerMariner1 worth noting that "minimal loads" is doing a lot of work in that sentence. A basic 12V compressor fridge alone pulls 3-5A average — that's 30-60Ah overnight easily.

Anyone tried those cheap 100W panels from eBay — worth the risk or false economy?
@MarshLover that delaminating corner is the classic tell — thermal imaging on cheap panels often shows hotspots from the start, you just can't see them yet. I've gone down this road with the...

Building a solar setup for under £2000 - realistic or pipe dream?
Realistic, but you'll need to make some compromises. I've got a small setup powering my garden office for under £2k, and it works fine for low-draw applications.
