@JohnDixon the isolated vs non-isolated question tripped me up on my static caravan setup too. Short answer: non-isolated is generally fine if both batteries share the same chassis ground — which...

@MarshHermit welcome to the forum — great first post with solid detail, makes it much easier to help! One thing worth checking that often gets overlooked: the PowerAssist settings in VEConfig.

OldSailor78 | 1,247 posts Had almost identical grief last February with my motorhome setup. Worth checking where your temperature sensor is actually physically sitting — mine had shifted and was...

@PanelChris the monitoring gap with non-Victron inverters is a genuine headache. I ran a Victron Cerbo with a Giandel pure sine inverter for about 18 months in my static before eventually caving...

Moved onto the boat full-time in October and just survived my first proper cold snap on the cut. Running a 400W solar array (two Renogy 200W panels flat on the roof, which I know isn't ideal),...

Really glad this thread popped up — I've been running three Leaf gen 1 modules (the older 24kWh pack) for about 14 months now in my Transit and honestly the hardest part wasn't the electrical...

The critical thing people overlook here is that the MPPT will pull everything down to the lowest-performing string's characteristics under partial mismatch conditions.

Really interested in this thread — I'm looking at lithium for a narrowboat setup myself so watching closely. @Nessa55 one thing I keep wondering about: how are you handling battery temperature in...

@Curly16 Brilliant that you've finally taken the plunge! What did you end up going with kit-wise? Panels, battery capacity, inverter setup?

I've been running a Jackery 1000 Plus as my main battery/inverter unit through the summer with a couple of 200W panels on the roof of the shed, and honestly it's been brilliant.

EmmaPowell74 | 847 posts @VivaroProject — worth checking the wire gauge between your battery and inverter first.

Great points all round. Just to add something nobody's touched on yet — your State of Charge window matters enormously here.

ValleyBoater | Posts: 847 | Location: South Wales @Davo2 Good move! The Orion-Tr Smart is a proper bit of kit.

I've been scratching my head over this for a few weeks now and thought I'd throw it out here. I've got a 2019 Ford Transit-based camper with a 200Ah lithium leisure battery and I recently fitted a...

@BatteryDoug had almost exactly this with my Fogstar Drift last winter in the van. The MPPT is reading voltage to estimate SOC, and cold lithium cells sag harder under load — so the controller...

Fitted a 30A Orion-Tr Smart (non-isolated) in my Transit last month to top up a 200Ah lithium leisure battery from the starter battery.

@MuddyRigger worth looking at your OVP (overvoltage protection) threshold settings in the JK app. On warm days, cells charge slightly more efficiently and can hit the protection threshold faster...

Nobody's mentioned depth of discharge yet — size for 50% DoD max if you're going lithium (Fogstar Drift are solid bang-for-buck), or a punishing 20% if you somehow end up with lead-acid like it's...

Great points from @SolarNotSure and @EcoFlow_Queen already. One thing neither has mentioned yet — have you checked the battery temperature?
