What actually determines whether a golf cart pack will play nicely with a standard solar charge controller?
@Chunk48 DESS and a hybrid inverter is either pure genius or a recipe for spending your evenings arguing with VRM at 11pm — speaking from bitter experience with my MultiPlus-II setup in a tin box...
HappyBuilder | 312 posts | 🏡 Tiny House & Boat Nerd @JulieGraham worth adding — the SmartShunt's charged detection settings matter a lot here.
Narrowboat here, Cerbo + Multiplus-II combo. Had something adjacent happen after a firmware push — DESS basically forgot my consumption baseline and started grid-importing at odd times. Worth...

Good shout from @VanGill on the inject node approach. One thing I'd add specifically for the generator auto-start flow — after any firmware update, double-check your AC input current limit MQTT...
@RetiredChef is absolutely right on pre-charge — but I'd go further and say if your inverter doesn't have a built-in pre-charge circuit (looking at you, cheaper units), that inrush current will...
@Cleggy yes, connecting through a Cerbo GX does help here actually. The Cerbo pulls the voltage and current data from the shunt and calculates the watt figure itself, displaying it properly in the...
@Chalky12 completely agree this documentation gap is a real problem. On my static caravan setup with a Quattro 10kVA and Symo 5.0, it took me the better part of a fortnight cross-referencing the...
With the SmartShunt, the golden rule I kept reminding myself when I wired up my boat setup was: everything — and I mean everything — goes through that shunt on the negative side.

Really interested in this thread - been eyeing up OpenEVSE for my setup for a while. @AngliaOffGrid did you find the current ramp rate settings made much difference to how smoothly it tracks solar...

@MountainHermit nailed the core issue but there's another layer worth flagging — golf cart packs are typically configured for 36V or 48V traction applications, so if you're trying to squeeze them...

@Rob1963 had this exact scenario play out in my cabin last spring — Multiplus-II, Cerbo GX, Fogstar Drift cells.

@Boycie25 the suspense is actually painful 😂 Right, I'll take a stab at what you might be referring to — with PowMr units there are a few culprits but the one that catches most people out is...
@ExFarmer90 seen something similar on my cabin setup — MultiPlus-II 48/3000 with Pylontech batteries.
Has anyone tested what actually happens with a floating chassis setup in a motorhome specifically? My situation is slightly different to a van build — the habitation area and cab are somewhat...

@Davo51 the 12/3000 can pull north of 250A at full whack — that's where the real culprit usually hides.
Interesting one this — does anyone know if this changes at all when the SmartShunt is connected through a Cerbo GX?

@PhilJackson been running a similar setup for about a year — Pi 4 with VenusOS pulling data from my Victron MPPT and Multiplus.
@AGM_Geek the Multiplus isn't being dramatic, it's just got better taste in appliances than you do — slap a soft starter on that compressor and watch your inverter suddenly rediscover its...
@HighlandExplorer is right, and honestly in my experience with my boat setup this is where lead acid really starts to show its age as a chemistry. One thing worth considering — active balancers...
