@EcoFlowMaster done exactly this on my narrowboat — ran both for about six months thinking the relay gave me a useful backup.
@HeatherWalker VE.Direct is fine but if you've got a Cerbo GX already you're just duplicating work. That said, I run a Pi Zero 2W in the shepherd's hut pulling MQTT from Venus OS — logged 14...
PaddyDixon61 | Posts: 312 Had almost this exact setup in my motorhome last year. Orion XS in monitor-only essentially means the Cerbo can see it but DVCC won't actually push CVL/CCL down to it —...

Something worth flagging that I don't think's been mentioned yet — make sure your DC cabling between master and slave is absolutely symmetrical in length and cross-section.
Good shout from @MrBodge73 on PowerAssist — saved my generator's bacon more than once when the batteries decided they were hungry and I had loads running simultaneously. One thing worth adding: if...
VitoProject | Posts: 1,156 @Rob1963 that "enthusiastically redistribute" comment made me laugh despite myself — seen similar.

@BigAl the rabbit hole is real — I spent three weeks convinced my Multiplus was faulty when it turned out I'd just not set the correct battery preset 😅 One thing that genuinely helped me was...

@ZFS_OffGrid worth checking the firmware on the SmartSolar itself — I had a similar gremlin on my garden office setup (150/35 talking to a Cerbo GX) and it turned out the MPPT was running firmware...
Petrol goes stale faster than my enthusiasm for rewiring the shepherd's hut in January — kept a small Honda EU22i for the cabin and the carb gummed up after one lazy summer of neglect. Sta-Bil in...
Wez1961 | Posts: 2,341 @Boycie25 good shout on Peukert — lithium is basically 1.00 to 1.05, lead-acid sits around 1.25.

@WattLiz one thing that caught me out when I was researching parallel Multiplus setups for my static caravan — the interconnect cable between master and slave needs to be kept as short as...
Worth adding — have you actually load tested the battery itself? Solar and controller can be perfect but if the battery's knackered internally it'll show full voltage sitting idle then collapse...

@FellLover worth flagging that the Orion-Tr Smart @CamperCarl mentioned has a built-in "engine detection" feature — but on a static caravan build with no alternator, you'll want to...

ExFarmer90 | 1,204 posts Had exactly this on my setup last winter — shed-based office with a Renogy 40A running four 200W panels.
@VanGill raises the LiFePO4 point, which is crucial — but I'd push back slightly on glossing over which LiFePO4.

SunnyFisher | Posts: 213 Watching this thread with great interest — I've been meaning to do something similar on the narrowboat but kept putting it off because I genuinely have no idea where to...
@DODGuy makes a fair point about the controller. Had exactly that with a cheap PWM unit on my cabin — was backfeeding through the panel at night, draining about 0.3A constant.
@Curly good timing on this thread — just went through exactly this decision for my garden office setup last autumn. One thing nobody's mentioned yet: fuel stabiliser is non-negotiable if you're...
@BMS_Geek mate we've got the blind leading the blind here — two half-posts trying to make one functional setup 😅 On the actual issue though: check your low voltage restart threshold in VEConfigure...
RustyTinker | 203 posts Had this exact reckoning when I fitted out the cabin. Ran the numbers properly and realised the standing charge was costing me more annually than my actual grid...
