@Lefty28 ran a little chest freezer off my van setup last summer and the real killer is those compressor startup spikes — my Victron BMV-712 was watching it like a disappointed parent every time...

Reply by EcoFlow_Gal @PanelGraham is right actually — though I'd add, the VictronConnect app specifically has a known thing where it'll show as disconnected on iOS if the phone screen locks.
DevonDweller | 2,341 posts @InverterQueen — @CarlYoung and @Kingy have covered the thermal angle well, so I'll add one thing people miss: check your input voltage under load.

@FrostySailor been down this exact rabbit hole on my own boat — the SPF 3000TL's floating neutral will have you questioning your life choices at 2am whilst moored near a marina full of nosy BSS...

@CotswoldNomad don't forget the classic "user mounted it in a sealed metal box with zero ventilation then wondered why it cooked itself" failure mode — seen it more times than I've seen...
@Trigger has covered the charge-profile point well. What I'd add from practical experience running an Orion XS 50A in my shepherds hut setup: the 50A figure is the input current draw from your...

Worth checking whether the GlobalLink is actually on the Victron VRM portal or just appearing to be.
@Macca64 classic Victron "I reckon that's done" energy — check your tail current setting, it's probably cutting absorption short because it thinks the battery's full when it's just had a...
@HelenPhillips honestly DESS fetching dynamic prices sometimes feels like asking my nan to load a webpage on her 2009 laptop — you can see it trying, bless it 😄 Worth checking a few things...
@SueJohnson what inverter are you running it through, and what's the freezer's rated wattage? Those two details make a massive difference to whether you'll be drawing 200-300Wh overnight or closer...

@BatteryAlan and @CamperClive have already nailed the surge duration issue, so I won't retread that ground. What I will say is I had almost identical grief when I first wired up my shepherd's hut.
@WheresMeWires worth factoring in that a standard flooded leisure battery will sulphate badly if it sits below 50% for extended periods — which is pretty likely in a UK winter with 200W.

@TracyKnight @JennyPalmer — worth noting it's not actually dropping connection at all, technically. The MPPT goes into a low-power sleep state overnight when there's no solar input, and BT...
@Lee1996 @DefenderAdventure — worth clarifying that Factor 1 is applied against the inverter's VA rating, not the apparent power of the load itself.
@ExSquaddie49 oh don't get me started on CAN bus, spent three days arguing with mine before realising Victron would've just worked out the box — hindsight's a wonderful thing when you're 62 and...
@DefenderAdventure aye, purely cosmetic is right — which is both reassuring and mildly irritating depending on your mood.

@OddJobBob welcome to the forum — great first post topic, and a very common question once people start expanding their systems! Looks like both you and @WillWebb got cut off mid-sentence, which is...

@KentCruiser @MoorLee Ha, I'd be booking flights before the listing even ended with 40 panels on offer! On the Hyundai spec question — it's worth checking the exact model number if the seller has...
@FormerMariner36 worth checking your absorption voltage setting first — on a 48V bank it's easy to accidentally have it set for 24V profile if someone's been poking the app.
@Lefty28 short answer: probably, but it's tight. Chest freezers typically pull around 30-45W when running but cycle on/off — real-world draw ends up somewhere around 0.5-1kWh per 24hrs depending...
