@SomersetVanLifer that distinction tripped me up with my shepherd's hut setup too. Worth adding — if you're running a Cerbo with a manual generator (no auto-start relay wired in), the Generator...

Been wrestling with exactly this kind of headache lately for the shepherd's hut build, so figured it's worth opening up the discussion here. I'm running a string of 400W panels that push Voc up...
Hamish1980 | 134 posts | ⚡ Member @OffGridDawn totally with you on this. What frustrates me is the IP65's weather resistance actually makes it ideal for outdoor or semi-exposed installations —...
Had this exact issue last summer with my Multiplus 12/3000. The spin cycle creates a massive inrush current spike that the inverter sees as an overload, even if your steady-state draw is well...
@EcoFlow_Master the suspense is genuinely killing me, but I'll carry on regardless. Did my van conversion two years back and wrestled with exactly this decision.
Been wondering about this myself — currently mid-build on my Transit and I've got the Orion-TR Smart sitting in a box waiting. @DefenderAdventure makes a good point about cross-sectional area that...

SimonThompson | Posts: 489 | ⛵ Boat & Backup Tinkerer Worth considering what you're actually running before jumping to a MultiPlus — brilliant bit of kit but serious overkill if you just need...
So I've been down a bit of a rabbit hole this week and wondered if anyone else has had a similar head-scratcher with their setup... My van's roof-mounted 200W array (two 100W panels wired in...
Been running a cheapo PWM controller on my shepherd's hut build for about 18 months now and honestly… it's fine? 😅 Not great, but fine. Cost me about £12 off Amazon and it's still chugging away.

Had this exact argument with my boat setup — spoiler: trust the Victron. The Daly BMS is great at protecting your cells but its SOC estimation is basically a rough guess dressed up in electronics...
@FellGraham good shout on the Gumout. I'd also check the fuel tap is fully open and the choke isn't stuck — sounds obvious but caught me out once with my old Kipor. If the carb's properly gummed...
Hey @Cerbo_Geek, great question. Worth thinking about usable capacity too — with lithium you're realistically pulling 80-90% of that 200Ah, so closer to 170Ah in practice.

Had this exact issue last summer with my 100/30 on the motorhome. Drove me absolutely mental for weeks. Turned out my battery voltage sense was way off — the MPPT was reading voltage at the...
Spot on from everyone here. One thing worth mentioning that hasn't been covered yet — if you're dead set on getting your grid-tie inverter visible properly in VRM, have a look at using a Fronius,...
@StormyWelder same story with my garden office setup — went 24v and the difference on surge loads was night and day. One thing nobody's mentioned yet: cable losses.

Good catch @LesWood78 — that distinction matters when you're planning cable runs and port counts on the Cerbo. Worth adding: once both the BMV-712 and MPPT are connected to the Cerbo via...
@BerlingoConvert I've not seen one opened up but if you dig around on the Photon forums and YouTube there are teardowns of suspiciously similar units under different badges — same PCB layouts,...

Has anyone checked whether the BMS is actually cutting out entirely overnight, or just throttling? On my shepherd's hut build I had a similar voltage drop and kept blaming the BMS, but the Victron...

Been lurking on this thread with interest — I've been toying with this for my cabin setup but haven't pulled the trigger yet. Quick question for those running it: how much of a faff is the initial...
Bit late to this thread but it's relevant to my static caravan setup so jumping in. @RKE_Builds that 6-8x figure is eye-opening — I'd always assumed my occasional trips on startup were a battery...
