@JackeryGuy I run a Jackery 500 alongside my 24V Victron setup specifically for EV trickle charging experiments — it's surprisingly useful as an isolated circuit for testing without touching the...

@BoxerDream this happened to me last winter when I was parked up in Scotland for three weeks running purely on solar.

There's a chapter in my narrowboat conversion where I agonised over exactly this. Went 24v, thought I was saving money and complexity — spent the next six months replacing undersized cable runs...

Moorey13 | 312 posts All good points above. One thing nobody's mentioned yet — insulation around the fridge matters nearly as much as the fridge itself.

HalfAJob53 | 312 posts @Charlie1981 @BurnKen The wire gauge thing is obviously a big deal but what sold me on 48V was the efficiency losses at higher currents on 12V.

RetiredChef | 847 posts @LazyWarden the elephant in the room nobody's poked yet — your Peukert exponent in the SmartShunt defaults to 1.25, which is a lead-acid assumption; LiFePO4 chemistry is...

Good shout from @WonkyWarden on the BMS side — worth adding that if you're using DVCC in VenusOS, make sure the CVL (Charge Voltage Limit) coming from your BMS isn't intermittently dropping below...

BigAl31 | Posts: 2,156 Good shout from @GafferTapeKing on transfer switching — worth adding that transfer time matters more than most people realise.

The DCC40S has a peculiar behaviour when the alternator output drops during low-RPM idling — it can cause the charger to cycle in and out of bulk mode repeatedly, which shows up as erratic voltage...

LazyFisher | Posts: 203 | Narrowboat My Fogstar pulled the same stunt moored up near Foxton last winter — turns out the bilge was colder than the ambient air temp the BMS was "reading,"...

Del6 | Posts: 847 @T6Project Congratulations on the boat! Good starting point is working out your actual daily consumption before buying anything — narrowboaters often underestimate how much a 12V...

@CamperRachel the SmartSolar's SOC estimation is genuinely unreliable without a dedicated battery monitor — it's essentially inferring state from voltage curves and charge current, which is...

@NickThompson65 Here's the thing nobody tells you until you're already disheartened and knee-deep in VRM data: a single 200W panel in the Peak District in December is essentially a very expensive...

@EllaDixon71 ran a similar "solar + genny as backup" combo in my van for 18 months and the honest truth is the generator mostly just sat there looking smug until January arrived and...
Great thread. @WonkyDrifter makes a fair point about the SmartShunt carrying some of the load here. One thing worth considering is setting up a custom VRM dashboard widget to track your battery...

Running a Victron SmartSolar 100/30 with a 200Ah AGM bank and a single 200W panel on the roof of my Transit conversion.

48VGal | 412 posts | Regular Member My garden office setup runs a Pi 4 with Venus OS and I've piped everything into InfluxDB + Grafana — the historical graphs are what sold it for me.

RM_Marine | 89 posts @SOCGal Solid choice with the Fogstar Drift — decent cells in those. Just to add something neither @Gibbo39 nor @MarineFrank have touched on yet: have you sorted your transfer...

Been running a 200W panel setup on my Transit conversion for about eight months now — two 100W Renogy panels in series feeding into a Victron SmartSolar 100/20, with a 100Ah lithium (a Fogstar...
