Been running a MultiPlus 12/3000/120 for about eight months now in a static off-grid setup — 400Ah of lithium, 800W of panels, and a Cerbo GX managing the lot.
LizWalker | 312 posts @T6Project Congratulations on making the switch! One thing worth doing early on is spending a day photographing your roof at different times — you'll quickly spot where...

HamishLee | 312 posts @Ben1973 One thing I'd add to what the others have said — these cheap units often have absolutely terrible temperature compensation, or none whatsoever.

Good timing on this thread — I've got a static caravan running almost exactly this kind of load and went through the same head-scratching about 18 months back. One thing nobody's touched on yet:...

Running a 200Ah Fogstar Drift lithium in my garden office, currently charged via a small Renogy 200W solar setup on the office roof.

Really good points already from @PanelLouise and @Chopper84. One thing I'd add that often gets overlooked at the planning stage — think carefully about your winter usage pattern, not just summer.

@Chippy33 Sounds familiar! I've got three of those mystery eBay panels running a similar setup. Honest numbers from last summer: on a decent July day I was seeing about 85-90W peak from each...

@MasterCamper Worth looking into a self-heating LiFePO4 if you plan on upgrading down the line, but for now a practical workaround is to keep a small 12V heating pad (the sort sold for reptile...

Ended up with a bit of a mongrel setup in my shepherd's hut — 400W of panels split across a Renogy Wanderer 40A and a Victron SmartSolar 100/20.
Interesting thread — I've got similar sizing questions but for a static caravan rather than a shepherd's hut.

Fitted a Multiplus-II 12/3000 in my Transit last spring alongside a 200Ah Fogstar Drift LiFePO4 and a 400W Victron MPPT setup.

Been putting off properly sorting the power for my 8x4m garden office for the best part of two years.

DownsCruiser | 847 posts | 🏕️ Motorhome/Cabin Had two of those mystery panels on the motorhome roof for about 18 months. Started delaminating at the edges by month 14.

Great thread @UWW_Power — I had almost identical behaviour with my Orion-Tr Smart before I sorted the wiring. Worth checking your voltage drop between the starter battery and the B2B input.

Sitting here in my static on the moor watching the Victron BMV-712 slowly weep as three consecutive grey days have hammered my 400Ah Fogstar lithium bank down to 38%.

TimGreen | 847 posts @RobWebb59 Classic cold weather LiFePO4 issue, unfortunately. The Daly's low-temperature charge protection kicks in somewhere around 0-5°C depending on the firmware — it's...

Something worth adding to the excellent points above - have you set up the battery profile correctly in the Victron Connect app?

Nice one @Gazza82 — love the commitment to going properly off-grid rather than just running a cable! What are you actually running in there? That'll make or break the system sizing conversation.

@RetiredNurse43 interesting setup to inherit — shore power dependency on a narrowboat is a real pain once you start wanting to cruise properly. I'm motorhome rather than marine, but the principles...
