Hey @Smithy51, looks like your post got cut off mid-sentence there! What were you going to say about the absorption cutoff behaviour?

My van's MultiPlus threw a tantrum over a 900W microwave until I bumped the overload trip delay up a notch in VictronConnect — buys it just enough time to survive the startup surge without nuking...

Started out with a 12V system in my shepherds hut — 200Ah Fogstar Drift LiFePO4, couple of 175W panels, Victron SmartSolar 100/30.

Smudge_6508 | Posts: 89 @Midge worth noting that the 200W panel will almost certainly have a different Voc and Vmp to your 175W ones, so in series your string voltage will be slightly...

@LesPhillips that "worked fine until it didn't" is exactly what worries me with these units.

@VivaroProject one thing nobody's mentioned yet — the Victron SmartSolar 100/30 has a relatively narrow MPPT tracking range.

Sam1985 | 578 posts Good thread this. One angle I'd add — if you're planning to use the Victron app to monitor everything, the SmartSolar already gives you really granular data on what's going in...

Interesting move @SilverSpanner — did you upgrade the external regulator at the same time, or are you running it on the internal one? Reason I ask: I've been weighing up a similar swap for my...

IanStevens | 67 posts | Regular Member Really interested in this thread — been thinking about doing something similar in my motorhome.

@JakeLee worth checking whether the Renogy is thermally throttling itself rather than the alternator being the bottleneck.

DalesSolar | 847 posts @ForestBoater good setup! One thing worth flagging with parallel Victrons into lithium — make sure you've got them networked via VE.Smart Networking (Bluetooth mesh) so...

Something nobody's mentioned yet — if you ever want to charge an EV at the cabin (even just a slow overnight top-up via a 3-pin), your battery sizing calculation changes dramatically.

Last summer I rewired my Transit-based camper and fitted a Victron Orion-Tr Smart 12/12-30A DC-DC charger to handle alternator charging properly.

So I've been scratching my head over this for a few weeks now. I've got a Renault Master (2019, Euro 6) with a 200Ah lithium leisure battery and a Sterling BB1230 B2B charger already fitted.

EdKelly | 1,203 posts @Curly — just to add to what @AndyReid is getting at, the startup surge is the killer here.

Looking at adding EV charging to my existing setup — currently running a 48V system with 15kWh of Fogstar Drift LiFePO4 and about 4kW of panels through a Victron MultiPlus-II.

@TH_OffGrid the missing piece nobody's mentioned yet is temperature compensation — a decent controller adjusts the charge voltage setpoints based on ambient temp, typically around -3mV per cell...

@VivaroNomad the narrowboat is where I've done most of my long-term testing, so slightly different use case to yours, but the principles stack up. Ran a Renogy 200Ah for about eighteen months...

EV charging from a 200Ah bank is essentially asking your system to donate a kidney every afternoon — done it in the van conversion and learned quickly that a dedicated EV charging buffer (I run a...
