@OddJobBob looks like your post got cut off mate — what's the second battery?
That said, charging two separate batteries from one MPPT is doable but gets messy fast.
Ran two Victron 75/15s on my shepherd's hut rather than one bigger unit — mainly because my panels are split across two roof pitches facing different directions.
The east/west split means they're...
@BoatFinn yeah the built-in MPPT on these cheap all-in-ones is often the weak link. Rated wattage means nothing if the controller's voltage window is too narrow or the max input current is...
@HeatherChild the RS parallel setup docs are notoriously rough — Victron's own community forum has a few threads that are actually more useful than the official manual tbh.
One thing that tripped...

@SparkyCaptain the 100/30 to 150/45 jump is significant on paper — that extra headroom on the input voltage matters if you're ever running panels...
Honestly, January is rough. The shepherd's hut project has basically stalled because every time I go out to do something useful it's either horizontal rain or I just can't face it in the dark at...
Been running a Victron MultiPlus in my shepherd's hut for about 18 months now and recently added a second array for the garden office.

Did exactly this for my shepherd's hut last spring — two 100Ah Fogstar Drift LiFePO4s replacing a knackered 200Ah AGM bank.

@MandyMorris had a similar scare with my shepherd's hut setup last winter. Turned out my battery was sitting at a low state of charge going into the outage — BMS tripped on...
Finally got the hut wired up properly last month. Running a 400W Renogy panel into a Victron SmartSolar 100/30 MPPT, with a 200Ah Fogstar Drift LiFePO4 as the battery.
@Neil1962 yeah this caught me out with my shepherd's hut setup. LiFePO4 voltage curve is basically flat across 20–80%, so voltage-based SOC is pretty much useless in that range.
What actually...
Got a shepherd's hut with a Multiplus 24/3000/70 myself @MarineAlan — almost identical setup to yours.
One thing nobody's mentioned yet: if you're using VE.Configure to set up the unit, there's an...
Had exactly this with mine in the shepherd's hut setup — turned out to be thermal shutdown. The Orion 30A runs hot and if it's in an enclosed space without airflow it'll cut out to protect...
Got a frustrating one here and wondering if anyone's been through similar.
Picked up three Victron AGM Super Cycle 12V/100Ah batteries from an authorised UK dealer about seven months ago for my...
